ABSTRACT

La tuberculosis bovina es una zoonosis causada por Mycobacterium bovis. El bovino es el huésped primario. Otras especies pueden ser infectadas (cerdos, cabras y caballos, entre otras). En el ser humano, el contagio puede ser por vía aérea (enfermedad pulmonar), clínicamente indistinguible de la producida por Mycobacterium tuberculosis, o por vía oral o cutánea, (formas extrapulmonares: digestiva, ganglionar, cutánea). Su contagio se ha relacionado principalmente al contacto con el ganado y al consumo de lácteos sin pasteurizar. También se notificó el posible contagio interpersonal.Se describe el caso de una paciente adolescente, proveniente de la provincia de Buenos Aires, con síndrome febril prolongado y conglomerado ganglionar abdominal, con antecedente de ingestión de leche no pasteurizada. Es fundamental alertar acerca de la importancia del procesamiento correcto de los alimentos, sobre todo en esta época en la que las nuevas tendencias alimentarias (ingestión de lácteos caseros o comprados en ferias informales) pueden poner en riesgo la salud.


Bovine tuberculosis is an infectious, zoonotic disease, caused by Mycobacterium bovis. The bovine is the primary host. Other species can be infected (pigs, goats, horses, etc). Man can be infected by air (lung disease), clinically indistinguishable from that produced by Mycobacterium tuberculosis or by oral or cutaneous route (extrapulmonary forms: digestive, lymph node, skin). Contagion has been mainly related to contact with livestock and the consumption of unpasteurized dairy products. It was also reported the possible contagion between people. It is described the case of an adolescent patient, from the province of Buenos Aires, with prolonged febrile syndrome and abdominal lymph node conglomerate, with a history of ingestion of unpasteurized milk. We consider the importance of warning about the correct processing of food, especially at this time when new food trends (homemade dairy intake or bought at informal fairs) could put the health of the population at risk.

ABSTRACT

Bovine tuberculosis (bTB) is an infectious disease caused by Mycobacterium bovis, affecting domestic animals, wild animals and humans. In captivity, for wild animals, bTB represents a risk to animal keepers and zoo visitors, in addition to the possibility of spreading the infection to domestic animals or through the trade of infected wild animals. Sambar (Cervus unicolor), red deer (Cervus elaphus) and fallow deer (Dama dama) from a safari park in the State of Rio Grande do Sul, Brazil, showed a clinical condition of dyspnea and weight loss. Some animals died and showed lesions suggestive of tuberculosis (LST), which were confirmed by histopathology. After the interdiction of the safari park by the state veterinary authorities, 281 deer were euthanized with the authorization of the "Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis" (IBAMA). Retropharyngeal and submandibular lymph nodes and viscera were collected from 21 animals, which were grown in Stonebrink medium for up to 90 days. After DNA extraction from the bacterial colonies, PCR was performed for targets flanking the region of differentiation 4 (RD4). Of the 21 samples, 14 (66.7%) presented LST with a granulomatous appearance, a whitish coloration, and caseous or calcified consistency, and seven samples (33.3%), showed no lesions. In the culture of 14 samples with LST, 13 (92.8%) presented bacterial growth compatible with M. bovis. In the cultivation of the seven samples without LST, four (57.1%) presented colonies compatible with M. bovis. PCR and DNA sequencing of the PCR amplicons detected as positive all the 17 (100%) bacteriological cultures suggestive of M. bovis, thus confirming the outbreak of bTB in deer. Decisions about positive tested and suspicious animals should be taken based on the evaluation of the risk of transmission to the rest of the zoological animals, animal welfare, conservation considerations and, the zoonotic potential of this pathogen.(AU)


A tuberculose bovina (bTB) é uma doença infecciosa causada por Mycobacterium bovis, afetando animais domésticos, animais selvagens e humanos. Para animais selvagens em cativeiro, a bTB representa um risco para os tratadores de animais e visitantes do zoológico, além da possibilidade de espalhar a infecção para animais domésticos ou por meio do comércio de animais silvestres infectados. Cervídeos sambar (Cervus unicolor), veado-vermelho (Cervus elaphus) e gamo (Dama dama) de um parque safári no Estado do Rio Grande do Sul, Brasil, mostraram uma condição clínica de dispneia e perda de peso. Alguns animais morreram e apresentaram lesões sugestivas de tuberculose (LST), as quais foram confirmadas por histopatologia. Após a interdição do parque safári pelas autoridades veterinárias estaduais, 281 veados sofreram eutanásia com a autorização do Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA). Os linfonodos retrofaríngeos e submandibulares e vísceras foram coletados de 21 animais, que foram cultivados em meio Stonebrink por até 90 dias. Após extração de DNA das colônias bacterianas, foi realizada PCR para alvos que flanqueavam a região de diferenciação 4 (RD4). Das 21 amostras, 14 (66,7%) apresentaram LST com aspecto granulomatoso, coloração esbranquiçada e consistência caseosa ou calcificada, e sete amostras (33,3%) não apresentaram lesões. Na cultura de 14 amostras com LST, 13 (92,8%) apresentaram crescimento bacteriano compatível com M. bovis. No cultivo das sete amostras sem LST, quatro (57,1%) apresentaram colônias compatíveis com M. bovis. A PCR e o sequenciamento de DNA dos fragmentos de PCR detectaram como positivo todas as 17 (100%) culturas bacteriológicas sugestivas de M. bovis, confirmando assim o surto de bTB em cervídeos. As decisões sobre animais positivos testados e suspeitos devem ser tomadas com base na avaliação do risco de transmissão para o restante dos animais zoológicos, bem-estar animal, considerações de conservação e no potencial zoonótico desse patógeno.(AU)

ABSTRACT

Mycobacterium bovis is responsible for bovine and buffalo tuberculosis, an important zoonotic disease with global distribution. The knowledge of the distribution and the precise identification of this disease, including advanced diagnoses such as spoligotyping, allows choosing the best strategies to fight the disease's progress. The present work aimed to investigate mycobacteria's presence, genotype their strains, and evaluate tuberculosis cases' spatial distribution from suggestive lesions in carcasses of bovine and buffalo inspected in slaughterhouses under an official inspection regime in the state of Bahia, Brazil. The study investigated 453,417 animals. Among these, 31 (0.007%) from 17 municipalities were suspected of tuberculosis. Among the culture medium growth, 95% of these were categorized as alcohol-acid resistant bacilli (BAAR). All isolates were subjected to spoligotyping and 95% were confirmed as M. bovis (SB0120, SB0121, SB0852, SB0828, SB0295, SB0881, SB1648, SB6119, SB0140, SB1055). The strain SB0120 was the most prevalent, and this profile has been described in cases of human tuberculosis by M. bovis, highlighting the zoonotic potential of this profile. This study also identified strains never reported in Bahia, highlighting a distinctive pattern from other parts of Brazil, besides mixed infections. Besides, to identify strains never before described in the state, highlighting a distinctive pattern in Brazil (SB6119 and SB0852, respectively). An unpublished profile was identified and inserted in the international database (Mbovis.org), named SB2715.(AU)


O Mycobacterium bovis é o responsável pela tuberculose bovina e bubalina, doença zoonótica importante e com distribuição global. O conhecimento da distribuição e a identificação precisa dessa enfermidade, incluindo diagnósticos mais avançados como o spoligotyping, permite escolher as melhores estratégias de combate ao avanço da doença. O presente trabalho objetivou investigar a presença de micobactérias, genotipar suas estirpes e avaliar a distribuição espacial dos casos de tuberculose a partir de lesões sugestivas nas carcaças de bovinos e bubalinos inspecionadas em frigoríficos sob regime de inspeção oficial no estado da Bahia. Foram investigados 453.417 animais dentre os quais 31 (0,007%) foram suspeitos de doença e provenientes de 17 municípios. Após o crescimento em meio de cultura, 95% foram categorizados como bacilos álcool-ácido resistentes (BAAR). Todos os isolados foram submetidos à spoligotyping e 95% foram confirmados M. bovis (SB0120, SB0121, SB0852, SB0828, SB0295, SB0881, SB1648, SB6119, SB0140, SB1055). A cepa SB0120 foi a mais prevalente e este perfil vem sendo descrito na literatura com casos de tuberculose humana por M. bovis ressaltando o potencial zoonótico deste perfil. Este estudo também identificou cepas nunca relatadas no estado da Bahia, destacando um padrão distinto de outras partes do Brasil, além da existência de infecções mistas. Permitiu ainda relatar linhagens nunca antes descritas no estado com destaque para um padrão novo no Brasil (SB6119 e SB0852 respectivamente). Um perfil inédito identificado foi identificado e inserido no banco de dados internacional (Mbovis.org), nomeado SB2715.(AU)

ABSTRACT

The application of spatial and temporal analysis in epidemiology aims to understand the causes and consequences of spatial and temporal heterogeneity in studies of infectious diseases. Bovine tuberculosis (bTB) is a chronic and progressive infectious disease caused by Mycobacterium bovis and is an important zoonosis worldwide. The aim of this study was to conduct spatial and temporal analyses of a secondary database of bTB-positive cases registered by the Federal Inspection Service in two slaughterhouses from the West of Minas mesoregion of Minas Gerais state, Brazil, from 2008 to 2012 and to suggest its use in epidemiological surveillance. The culled cattle with bTB macroscopic lesions during post mortem inspection were considered positive in this study. The data used were the positive cases registered on the "Sistema de Informações Gerenciais do Serviço de Inspeção Federal" (SIG/SIF - Management Information System of the Federal Inspection Service) of the "Ministério da Agricultura, Pecuária e Abastecimento" (MAPA - Ministry of Agriculture, Livestock and Supplies), the number of animals slaughtered monthly and their municipalities of origin, per slaughterhouse. The prevalence (%) of cases per cattle slaughtered was calculated, and the relationship between these cases of bTB and cases of human tuberculosis (hTB) and the GDP per capita of the mesoregions comprising the municipalities surveyed was evaluated. The prevalence was 1,030 cases of bTB (0.28%). The lowest case numbers and prevalence rates were obtained in 2010, while the highest rates were observed in 2011. Slaughterhouse 1 showed stationarity, while Slaughterhouse 2 showed an increasing annual trend for data since October 2009. A statistical correlation between the numbers of cases of bovine and human TB (p=0.006, r=0.148) was observed. The prevalence for Slaughterhouses 1 and 2 were not correlated (p>0.05). The municipalities of origin demonstrated randomness in their spatial distribution. SIG/SIF-MAPA may be used for the analysis of spatial and temporal distribution to contribute to the monitoring of animal health services with information on the prevalence of culling for bTB in the West of Minas, South/Southwest of Minas, Campo das Vertentes and Zona da Mata mesoregions of Minas Gerais, Brazil.(AU)


A aplicação de análises espacial e temporal em epidemiologia visa compreender as causas e consequências da heterogeneidade espacial e temporal nos estudos de doenças infecciosas. A tuberculose bovina (TBb) é uma doença infecciosa crônica e progressiva causada pelo Mycobacterium bovis e uma importante zoonose em todo o mundo. O objetivo deste estudo foi realizar análises espaciais e temporais em um banco de dados secundário de casos positivos de TBb registrados pelo Serviço de Inspeção Federal em dois frigoríficos da mesorregião Oeste de Minas, estado de Minas Gerais, Brasil, de 2008 a 2012 e sugerir sua utilização na vigilância epidemiológica. Os bovinos abatidos com lesões macroscópicas de TBb durante a inspeção post mortem foram considerados positivos neste estudo. Os dados utilizados foram os casos positivos cadastrados no Sistema de Informações Gerenciais do Serviço de Inspeção Federal do Ministério da Agricultura, Pecuária e Abastecimento (SIGSIF/MAPA), o número de animais abatidos mensalmente e seus municípios de origem, por frigorífico. Foi calculada a prevalência (%) de casos por bovinos abatidos e avaliada a relação entre esses casos de TBb e os casos de tuberculose humana (TBh) e o PIB per capita das mesorregiões que compõem os municípios pesquisados. A prevalência foi de 1.030 casos de TBb (0,28%). Os menores números de casos e prevalências foram obtidos em 2010, enquanto as maiores prevalências foram observadas em 2011. O Frigorífico 1 apresentou estacionariedade, enquanto o Frigorífico 2 apresentou tendência anual crescente para os dados desde outubro de 2009. Correlação estatística entre o número de casos de TBb e TBh (p=0,006, r=0,148) foi observada. As prevalências nos Frigoríficos 1 e 2 não se correlacionaram (p>0,05). Os municípios de origem demonstraram aleatoriedade em sua distribuição espacial. O SIGSIF/MAPA pode ser utilizado para a análise da distribuição espacial e temporal a fim de contribuir com o monitoramento dos serviços de saúde animal com informações sobre a prevalência de condenações por TBb nas mesorregiões Oeste de Minas, Sul/Sudoeste de Minas, Campo das Vertentes e Zona da Mata de Minas Gerais, Brasil.(AU)

ABSTRACT

Bovine tuberculosis (BTB) is a zoonosis caused by the bacterium Mycobacterium bovis, which induces the development of nodular and granulomatous lesions in various animal tissues. The recognition of these suggestive gross lesions during postmortem sanitary inspection in slaughterhouses provides a presumptive diagnosis, which requires the use of complementary tests to confirm the disease. This study aimed to verify the occurrence of BTB in cattle slaughtered in slaughterhouses in the state of Ceará, Brazil, using bacteriological and molecular methods. To this end, suggestive lesions were analyzed on carcasses condemned by the "Serviço de Inspeção Estadual" (SIE). The samples were submitted to microbiological analysis using culture media and specific staining followed by spoligotyping molecular technique for identification and genotyping of the mycobacteria. Occurrence of lesions suggestive of BTB was verified in bovine carcasses (0.071%) from different municipalities of the state. These lesions were located mainly in the lung (95.12%), lymph nodes (58.53%), and liver (36.58%). Microbiological culture showed bacterial isolation (17.94%), with the growth of colonies showing morphological and tannic characteristics belonging to genus Mycobacterium spp. Genetic polymorphism analysis identified M. bovis in all isolates, which were discriminated into six spoligotypes (SB0121, SB0295, SB1064, SB0120, SB0870, and SB0852). These profiles have been described in Brazil and several areas of the world, except for profiles SB1064 and SB0852, which were described in the country for the first time. The results show that the association of the diagnostic methods used was the basis for the first study on identification of mycobacteria found in the state, which may provide a database for the epidemiological study of BTB in the state of Ceará.(AU)


A tuberculose bovina (TB) é uma zoonose causada pelo Mycobacterium bovis, o qual induz ao desenvolvimento de lesões nodulares e granulomatosas em vários tecidos do animal. O reconhecimento dessas lesões macroscópicas sugestivas durante a inspeção sanitária post mortem em matadouros fornece um diagnóstico presuntivo, sendo necessário a utilização de testes complementares para confirmação da doença. O objetivo deste trabalho foi verificar a ocorrência da TB em animais abatidos em matadouros-frigoríficos no estado do Ceará através da utilização de métodos bacteriológicos e moleculares. Para tanto, foram analisadas lesões sugestivas de TB em carcaças condenadas pelo Serviço de Inspeção Estadual (SIE). As amostras foram submetidas à análise microbiológica, utilizando meios de cultivo e de coloração específicos, seguida pela técnica molecular spoligotyping para identificação e tipificação genética da micobactéria. Verificou-se a ocorrência de lesões sugestivas de TB em carcaças bovinas (0,071%) oriundas de diferentes municípios do estado do Ceará. Essas lesões estavam localizadas principalmente no pulmão (95,12%), linfonodos (58,53%) e fígado (36,58%). O cultivo microbiológico obteve isolamento bacteriano (17,94%), com o crescimento de colônias apresentando características morfológicas e tintoriais pertencentes ao gênero Mycobacterium spp. A análise do polimorfismo genético identificou a presença de M. bovis em todos os isolados, que foram discriminados em seis espoligotipos (SB0121, SB0295, SB1064, SB0120, SB0870 e SB0852), descritos no Brasil e em diversas áreas do mundo, exceto os perfis SB1064 e SB0852 que foram descritos pela primeira vez no país. Os resultados obtidos demonstram que a associação dos métodos diagnósticos utilizados foram a base do primeiro estudo de identificação das micobactérias encontradas no estado do Ceará, o que pode contribuir para a criação de um banco de dados para o estudo epidemiológico da TB no estado.(AU)

ABSTRACT

BACKGROUND Bacillus Calmette-Guérin (BCG) is considered a promising live bacterial delivery system. However, several proposals for rBCG vaccines have not progressed, mainly due to the limitations of the available expression systems. OBJECTIVES To obtain a set of mycobacterial vectors using a range of promoters with different strengths based on a standard backbone, previously shown to be stable. METHODS Mycobacterial expression vectors based on the pLA71 vector as backbone, were obtained inserting different promoters (PAN, PαAg, PHsp60, PBlaF* and PL5) and the green fluorescence protein (GFP) as reporter gene, to evaluate features such as their relative strengths, and the in vitro (inside macrophages) and in vivo stability. FINDINGS The relative fluorescence observed with the different vectors showed increasing strength of the promoters: PAN was the weakest in both Mycobacterium smegmatis and BCG and PBlaF* was higher than PHsp60 in BCG. The relative fluorescence observed in a macrophage cell line showed that PBlaF* and PHsp60 were comparable. It was not possible to obtain strains transformed with the extrachromosomal expression vector containing the PL5 in either species. MAIN CONCLUSION We have obtained a set of potentially stable mycobacterial vectors with a arrange of expression levels, to be used in the development of rBCG vaccines.

ABSTRACT

Bacillus Calmette Guerin (BCG) vaccines comprise a family of related strains. Whole genome sequencing has allowed the better characterisation of the differences between many of the BCG vaccines. As sequencing technologies improve, updating of publicly available sequence data becomes common practice. We hereby announce the draft genome of four commonly used BCG vaccines in Brazil, Argentina and Venezuela.

ABSTRACT

BACKGROUND: Rapid and accurate detection of Mycobacterium tuberculosis (MTB) is of primary importance for infection control and selection of anti-tuberculosis drugs. However, most clinical laboratories report MTB complex (MTC) without reporting MTB because MTC comprising MTB, Mycobacterium bovis, Mycobacterium africanum, Mycobacterium microti, Mycobacterium caprae and Mycobacterium pinnipedii have 99.9% similarity at the nucleotide level and identical 16S rRNA sequences. This study was conducted to analyze the species frequency of MTC isolates obtained from clinical specimen.METHODS: Of 310 MTC isolates obtained from clinical samples in a tertiary care hospital from February 2017 to August 2018, MolecuTech Real TB-Taq (YD Diagnostics, Korea) real-time PCR was performed, specifically to detect MTB. For DNA showing MTB negative results by MTB-specific real-time PCR or pyrazinamide-resistant strains, PCR-based MTC typing, spoligotyping, and exact tandem repeat D gene sequencing were performed.RESULTS: All the 310 MTC isolates were identified to be MTB. Two MTB strains of East-African-Indian 4-Vietnam genotype, which have not been reported in Korea, were also found.CONCLUSION: There was no zoonotic tuberculosis in this study. Since we investigated only 310 MTC isolates detected in only one medical institution, multi-center study is needed to accurately know the prevalence of zoonotic tuberculosis in Korea.

ABSTRACT

Este artigo tem como objetivo relatar um caso de infecção por Mycobacterium bovis em um gato doméstico, com seis meses de idade, enfatizando seus aspectos clínicos e terapêuticos. O felino apresentava como histórico a ingestão de leite de vaca não fervido e posteriormente desenvolveu sinais de anorexia, tosse não produtiva e linfadenomegalia. Para elucidação do diagnóstico, foram realizados exames complementares de imagem, hematológicos, citológicos e reação em cadeia da polimerase (PCR). Diante da confirmação de infecção por Mycobacterium, o tratamento foi instituído por meio da associação de três antimicrobianos (enrofloxacino 5mg/kg, claritromicina 10mg/kg e rifampicina 15mg/kg), por via oral, a cada 12 horas, aos quais o animal respondeu positivamente, apresentando significativa diminuição dos sinais clínicos; entretanto, após 60 dias de tratamento, foi a óbito devido a um atropelamento. Conclui-se que a realização do tratamento em gatos com tuberculose pode ocasionar melhora dos sinais clínicos e que, embora de ocorrência rara no Brasil, essa enfermidade deve ser incluída como diagnóstico diferencial das enfermidades infecciosas nessa espécie.(AU)


This article aims to report a case of Mycobacterium bovis infection in a six-month-old domestic cat, emphasizing its clinical and therapeutic aspects. The feline presented as history the intake of unboiled cow's milk and later developed signs of anorexia, non-productive cough and lymphadenomegaly. Additional imaging, hematological, cytological and polymerase chain reaction (PCR) tests were performed to elucidate the diagnosis. In the presence of Mycobacterium infection, treatment was instituted by the combination of three antimicrobials (Enrofloxacin 5mg/kg, Clarithromycin 10mg/kg, and Rifampicin 15mg/kg) orally every 12 hours, to which the animal responded positively, presenting significant decrease of the clinical signs, however after 60 days of treatment the cat died accidentally, hit by a car on the street. It is concluded that the treatment in cats affected by tuberculosis can cause improvement of clinical signs and that although rare in Brazil, this disease should be included as a differential diagnosis of infectious diseases in this species.(AU)

ABSTRACT

La vacuna con el bacilo de Calmette-Guérin es una vacuna atenuada utilizada para prevenir formas graves de tuberculosis. Se aplica a los recién nacidos en países con alta prevalencia de tuberculosis. Pueden presentarse, después de su aplicación, complicaciones a nivel local, como supuración o adenopatías regionales. La enfermedad por diseminación del bacilo es infrecuente y ocurre, por lo general, en pacientes con alteraciones inmunitarias subyacentes. Se presenta el caso de un niño de 5 meses que ingresó por un cuadro de 2 meses de evolución con detención del aumento de peso y nódulos subcutáneos. Se sospechó enfermedad por diseminación del bacilo y se diagnosticó por la biopsia de las lesiones. Se realizó el tratamiento con tres drogas antituberculosas, y se recuperó clínicamente. Si bien se realizaron estudios inmunológicos, no logró demostrarse ninguna inmunodeficiencia como afección predisponente.


The bacillus Calmette-Guérin vaccine is an attenuated vaccine historically used to prevent severe forms of tuberculosis. It is applied to all newborns in countries with high prevalence of tuberculosis. Local complications, such as suppuration or regional adenopathies, may occur after application. Disease due to the spread of the bacillus is infrequent, usually occurring in a patient with an underlying immune alteration. We present the case of a 5-month-old child who was admitted due to a 2-month evolution with weight loss and subcutaneous nodules. Disease was suspected to be due to bacillus Calmette-Guérin dissemination, being diagnosed by biopsy of the lesions. Treatment was carried out with three antituberculous drugs, evolving towards clinical recovery. Although immunological studies were carried out, no immunodeficiency could be demonstrated as a predisposing condition.

ABSTRACT

La tuberculosis bovina es una enfermedad infectocontagiosa producida por Mycobacterium bovis, que, junto con otras micobacterias, compone el complejo Mycobacterium tuberculosis. Su prevención radica en detectar la infección en el ganado bovino y pasteurizar la leche. El hombre, clásicamente, ha adquirido la enfermedad por contacto con el ganado, en el contexto de una zoonosis laboral, o por consumo de productos lácteos no pasteurizados. Se describe el caso de un paciente de 10 años, sin actividades relacionadas con animales, que presenta una forma de tuberculosis pulmonar por M. bovis, indistinguible clínica y radiológicamente de la tuberculosis humana. Se destaca la importancia de la detección de la enfermedad, del control sanitario de los alimentos y del primer nivel de atención en lo que respecta al reconocimiento de la enfermedad y a su prevención en la población.


Bovine tuberculosis is a contagious infectious disease produced by Mycobacterium bovis, which together with other mycobacteria makes up the Mycobacterium tuberculosis complex. Its prevention lies in detection of the infection in cattle and milk pasteurization. Man has traditionally acquired the disease through contact with livestock, in the context of an occupational zoonosis, or through consumption of unpasteurized dairy products. We describe the case of a 10-year-old male patient, without activities related to animals, that presents a form of pulmonary tuberculosis due to M. bovis, clinically and radiologically indistinguishable from human tuberculosis. The importance of the disease detection, the food sanitary control, and the first level of attention, with respect to the recognition of the disease and its prevention in the population, is highlighted.

ABSTRACT

A tuberculose continua sendo uma doença relevante no que diz respeito à saúde mundial. A doença é causada pelo bacilo Mycobacterium tuberculosis e a única medida profilática disponível é a vacinação com BCG, uma cepa atenuada derivada de M. bovis. BCG é uma família de diferentes cepas que possuem diferenças genéticas entre si. Pequenas mutações em sequências codificantes podem causar impactos funcionais relevantes, modificando drasticamente a função/estrutura da proteína ou até alterando o nível de expressão, devido à modificação de processos de transcrição/tradução. Para melhor compreender o impacto dessa categoria de mutação na biologia do BCG, identificamos e selecionamos casos de mutação em três loci preditos de estarem envolvidos em processos biológicos importantes para micobactérias, como metabolismo redox (dodecina ­ rv1498A), metabolismo lipídico (homólogo de rv1371/2/3) e respiração anaeróbica (fumarato redutase). Essas mutações foram identificadas pela análise de genômica comparativa entre M. tuberculosis H37Rv e M. bovis BCG Moreau. Análises de RT-PCR e western blotting mostram que a transcrição e tradução desses genes não foram afetadas pelas mutações. Modelagem estrutural das proteínas mutadas indica um drástico impacto na atividade de dodecina, corroborado por nossos ensaios funcionais, diferentemente do complexo da fumarato redutase. Mutantes knockout foram criados e resultados preliminares mostram que o operon da fumarato redutase é funcional em BCG Moreau, já que o mutante frd possui um fenótipo diferencial no crescimento quando comparado com a cepa selvagem


Já para rv1371/2/3 não foi observado tal padrão. Complementação da cepa selvagem com alelos de rv1371/2/3 de M. tuberculosis e BCG corrobora a hipótese de não-funcionalidade da cópia de BCG, já que identificamos lipídeos diferentes quando ambas as cepas foram comparadas. Não foi viável a inativação do gene codificante para dodecina, nem a construção da cepa de knockdown condicional, que seria utilizada para analisar a essencialidade desse gene. Complementação de M. smegmatis com os alelos de rv1498A de M. tuberculosis e BCG mostram que ambas as cópias resultaram em maior crescimento das cepas em meio axênico, em uma magnitude similar para ambos os alelos em comparação com a cepa selvagem. Análises proteômicas revelam que diversos genes com pequenas mutações que possuem diferenças em seu nível de expressão quando comparadas as diferentes fases de crescimento estão envolvidos em metabolismo lipídico, revelando a importância de se investigar tal característica. Nossos resultados mostram que algumas mutações preditas podem não causar o impacto funcional esperado, provavelmente porque forças seletivas podem estar atuando sob esses loci. (AU)

ABSTRACT

Objetivos: Identificar e comparar grupos de pacientes potencialmente de risco para tuberculose zoonótica (TBz), investigando a existência de fatores associados. Apresentar a distribuição espacial dos casos de tuberculose (TB) em bovinos e dos casos humanos. Método: Trata-se de estudo descritivo de casos confirmados de TB por todas as formas clínicas, residentes no estado de São Paulo, do período de 2006 a 2015. Definiram-se seis grupos potenciais de risco para TBz conforme critérios estabelecidos pela literatura. A análise descritiva foi realizada separadamente para pacientes menores de 15 anos e pacientes com 15 anos ou mais de idade, comparando os grupos identificados com a população de estudo por meio do teste do Qui-quadrado/Exato de Fisher. A existência de associação entre TB intestinal e/ou ganglionar (aceita como proxy de caso suspeito de TBz) e as exposições de interesse foi investigada pelas estimativas da odds ratio bruta e ajustada, com os respectivos intervalos de 95% de confiança, usando regressão logística. . A distribuição dos casos suspeitos foram apresentados em mapas temáticos. Resultados: Aplicados os critérios estabelecidos para o estudo, foram incluídos 190.368 casos de TB por todas as formas clínicas. Dentre estes: 134 tinham menos de 15 anos e residiam em municípios com até 20.000 habitantes (grupo A); os demais tinham 15 anos ou mais, sendo 1.238 trabalhadores rurais (grupo B); 201 magarefes (grupo C); 1.012 residiam em municípios com até 20.000 habitantes e com rebanhos infectados pela TB (grupo D); 2.776 imigrantes sul americanos (grupo E); e 160 imigrantes africanos (grupo F). Os grupos B e F foram os que mais apresentaram características semelhantes à TBz descrita na literatura, destacando-se no grupo B as maiores proporções de casos de residentes em municípios com caso de TB em bovinos e das formas intestinal e ganglionar periférica. Enquanto que no grupo F verificou-se maior proporção de casos com a forma clínica ganglionar periférica e de coinfecção HIV/TB. Os grupos A, C e D também apresentaram características distintas em relação ao total de casos de TB e associadas à TBz segundo a literatura, porém de maneira menos nítida. O grupo E não apresentou características relacionadas aos casos típicos da TBz. Dentre os pacientes menores de 15 anos de idade, após ajustes, destacaram-se como fatores associados à TB ganglionar e/ou intestinal, residir em município com menores índices de urbanização e com casos de TB em bovino conforme registro oficial. Entte os pacientes com 15 anos ou mais de idade, destacaram-se as associações com a ocupação de trabalhador rural e com a de magarefe. A distribuição dos tipos de rebanhos bovinos foi ampla sendo registrados casos da doença em animais em praticamente todas as regiões do estado. Conclusões: Os dados de vigilância da TB humana e animal, permitiram identificar grupos de pacientes com características associadas à TBz, salietando a importância da aplicação da proposta de Saúde Única, além de oferecerem subsídios para o desenvolvimento de um componente para TBz na vigilância da TB no estado de São Paulo, assim como, para pesquisas sobre o tema


Objectives: To identify and compare groups of patients potentially at risk for zoonotic tuberculosis (zTB), investigating the existence of associated factors. To present the spatial distribution of cases of tuberculosis (TB) in cattle and human cases. Method: This is a descriptive study of confirmed cases of TB by all clinical forms, residents in the state of São Paulo, from 2006 to 2015. Six potential risk groups for zTB were defined according to literature. The descriptive analysis was performed separately for patients younger than 15 years and patients 15 years of age or older, comparing the groups identified with the study population using the Chi-square / Fisher\'s Exact test. The existence of an association between intestinal and/or ganglion TB (accepted as a proxy for a suspected zTB case) and the exposures of interest was investigated by the estimates of the crude and adjusted odds ratio, with the respective 95% confidence intervals, using logistic regression. The distribution of suspected cases was presented in thematic maps. Results: After applying the criteria established for the study, 190,368 TB cases were included in all clinical forms. Among them: 134 were less than 15 years old and lived in municipalities with up to 20,000 inhabitants (group A); the others were 15 years old or over, with 1,238 rural workers (group B); 201 magarefes (group C); 1,012 resided in municipalities with up to 20,000 inhabitants and with herds infected by TB (group D); 2,776 South American immigrants (group E); and 160 African immigrants (group F). Groups B and F were the ones that presented the most similar characteristics to the zTB described in the literature. In group B, the highest proportions of cases of residents in municipalities with cases of TB in cattle and of the intestinal and peripheral ganglion forms were highlighted. While in the F group there was a higher proportion of cases with peripheral ganglionic form and HIV / TB co-infection. Groups A, C and D also presented distinct characteristics in relation to total TB cases and associated with TB, according to the literature, but less clearly. Group E did not present characteristics related to typical zTB cases. Among patients younger than 15 years of age, after adjustments, they were identified as factors associated with lymph node and/or intestinal TB, living in a municipality with lower rates of urbanization and with cases of TB in cattle according to official records. Among the patients aged 15 years and over, the associations with the occupation of rural workers and magarefe stood out. The distribution of bovine herd types was extensive and cases of the disease were recorded in animals in practically all regions of the state. Conclusions: Human and animal TB surveillance data allowed the identification of groups of patients with characteristics associated with zTB, stressing the importance of applying the One Health proposal, as well as providing subsidies for the development of a component for zTB in TB surveillance in the state of São Paulo, as well as for research on the subject

ABSTRACT

BACKGROUND: Mycobacterium bovis Bacille Calmette-Guérin (BCG) osteitis, a rare complication of BCG vaccination, has not been well investigated in Korea. This study aimed to evaluate the clinical characteristics of BCG osteitis during the recent 10 years in Korea. METHODS: Children diagnosed with BCG osteitis at the Seoul National University Children's Hospital from January 2007 to March 2018 were included. M. bovis BCG was confirmed by multiplex polymerase chain reaction (PCR) in the affected bone. BCG immunization status and clinical information were reviewed retrospectively. RESULTS: Twenty-one patients were diagnosed with BCG osteitis and their median symptom onset from BCG vaccination was 13.8 months (range, 6.0–32.5). Sixteen children (76.2%) received Tokyo-172 vaccine by percutaneous multiple puncture method, while four (19.0%) and one (4.8%) received intradermal Tokyo-172 and Danish strain, respectively. Common presenting symptoms were swelling (76.2%), limited movement of the affected site (63.2%), and pain (61.9%) while fever was only accompanied in 19.0%. Femur (33.3%) and the tarsal bones (23.8%) were the most frequently involved sites; and demarcated osteolytic lesions (63.1%) and cortical breakages (42.1%) were observed on plain radiographs. Surgical drainage was performed in 90.5%, and 33.3% of them required repeated surgical interventions due to persistent symptoms. Antituberculosis medications were administered for a median duration of 12 months (range, 12–31). Most patients recovered without evident sequelae. CONCLUSION: Highly suspecting BCG osteitis based on clinical manifestations is important for prompt management. A comprehensive national surveillance system is needed to understand the exact incidence of serious adverse reactions following BCG vaccination and establish safe vaccination policy in Korea.

ABSTRACT

With progress in sensors and communication technologies, the range of sleep monitoring is extending from professional clinics into our usual home environments. Information from conventional overnight polysomnographic recordings can be derived from much simpler devices and methods. The gold standard of sleep monitoring is laboratory polysomnography, which classifi es brain states based mainly on EEGs. Single-channel EEGs have been used for sleep stage scoring with accuracies of 84.9%. Actigraphy can estimate sleep effi ciency with an accuracy of 86.0%. Sleep scoring based on respiratory dynamics provides accuracies of 89.2% and 70.9% for identifying sleep stages and sleep effi ciency, respectively, and a correlation coeffi cient of 0.94 for apnea–hypopnea detection. Modulation of autonomic balance during the sleep stages are well recognized and widely used for simpler sleep scoring and sleep parameter estimation. This modulation can be recorded by several types of cardiovascular measurements, including ECG, PPG, BCG, and PAT, and the results showed accuracies up to 96.5% and 92.5% for sleep effi ciency and OSA severity detection, respectively. Instead of using recordings for the entire night, less than 5 min ECG recordings have used for sleep effi ciency and AHI estimation and resulted in high correlations of 0.94 and 0.99, respectively. These methods are based on their own models that relate sleep dynamics with a limited number of biological signals. Parameters representing sleep quality and disturbed breathing are estimated with high accuracies that are close to the results obtained by polysomnography. These unconstrained technologies, making sleep monitoring easier and simpler, will enhance qualities of life by expanding the range of ubiquitous healthcare.

ABSTRACT

Although intravesical instillation of Mycobacterium bovis bacillus Calmette-Guérin (BCG) is the most successful cancer immunotherapy for superficial bladder cancer, the serious side effects are frequently arisen by using live mycobacteria. To allow less toxic and more potent immunotherapeutic agents following intravesical BCG treatment for superficial bladder cancer, noninfectious immunotherapeutic drug instead of live BCG would be highly desirable. Recently, immune-enhancing adjuvants are considered an effective vaccine immunotherapy for cancer, providing enhanced antitumor effects and boosted immunity. The BCG-cell wall skeleton (BCG-CWS), the main immune active center of BCG, is a potent candidate as a noninfectious immunotherapeutic drug instead of live BCG against bladder cancer. However, the most limited application for anticancer therapy, it is difficult to formulate a water-soluble BCG-CWS due to the aggregation of BCG-CWS in both aqueous and nonaqueous solvents. To overcome the insolubility and improve the internalization of BCG-CWS into bladder cancer cells, it should be developed the lipid nanoparticulation of BCG-CWS, resulting in improved dispensability, stability, and small size. In addition, powerful technology of delivery systems should be applied to enhance the internalization of BCG-CWS, such as encapsulated into lipid nanoparticles using novel packaging methods. Here, we describe the progress in research on effects of BCG-CWS for cancer immunotherapy, development of lipid-based solvent, and packaging method using nanoparticles with drug delivery system.
