ABSTRACT

Estudo descritivo retrospectivo realizado no Instituto Nacional do Câncer José Alencar Gomes da Silva, HCI-Rio de Janeiro, Brasil, (INCA-HCI-RJ), no qual foram avaliadas infecções relacionadas aos acessos venosos para tratamento oncológico, nos setores Onco-Hematológicos pediátricos. A infecção representa uma importante complicação em pacientes oncológicos em tratamento. Devido ao tratamento oncológico que envolve: procedimentos cirúrgicos muitas vezes mutilantes, tratamento com quimioterápicos que ocasionam períodos de imunossupressão e neutropenia, e tratamento radioterápico com radiação e lise celular. O uso de dispositivos venosos associados a períodos de imunossupressão pode levar a infecção da corrente sanguínea e outras complicações (por exemplo trombose). No presente estudo foram investigados aspectos clínico-epidemiológicos das infecções e da susceptibilidade antimicrobiana em amostras clínicas obtidas de processos infecciosos associados ao uso de cateteres venosos de longa permanência no tratamento oncológico em pacientes do Hospital do Câncer José de Alencar Gomes da Silva, HCI/INCA, Rio de Janeiro Brasil. Foram avaliadas: a) prevalência das espécies diversas relacionadas aos quadros infecciosos identificados nestes pacientes oncológicos; b) prevalência de casos de complicações e outras infecções invasivas relacionadas ao uso de cateteres de longa permanência; c) perfis de susceptibilidade a antimicrobianos e ocorrência de multirresistência. O desenvolvimento deste projeto de pesquisa possibilitou a observação análise e validação da evolução dos processos envolvidos nos quadros de infecções nosocomiais em pacientes oncológicos pediátricos na prevenção de complicações que envolvem todo o sistema de saúde, além de contribuir na escolha de antimicrobianos e estratégias terapêuticas mais efetivas para o tratamento de infecções em cateteres por espécies multirresistentes de Corynebacterium.


Retrospective descriptive study conducted at the National Cancer Institute José Alencar Gomes da Silva, INCA / HCI-Rio de Janeiro, Brazil, (INCA-HCI-RJ). Infection represents an important complication in cancer patients. This group is more prone to infections due to the cancer treatment that involves: surgical procedures often mutilating, treatment with chemotherapy that cause periods of immunosuppression even with neutropenia, and radiotherapy treatment with radiation and cell lysis. The vascular devices associated with these periods can lead to bloodstream infection besides others complication as thrombosis. The number of reports of infections in hospitalized cancer patients increases morbidity and mortality rates. In the present study clinical and epidemiological aspects of infections were identified and antimicrobial susceptibility were investigated in clinical exams and samples from blood patients and venous catheter in children oncological patients at the José de Alencar Gomes da Silva, HCI / INCA, Rio de Janeiro Brazil. It was possible evaluate a) prevalence of various species infections in cancer patients; b) prevalence of cases of complications and other invasive infections related to the use of long-term catheters; c) antimicrobial susceptibility profiles and occurrence of multidrug resistance. The development of this research project in nosocomial infections in pediatric cancer patients was enabled analysis and validation of some process involved to prevent vascular complications that involve entire health system. In addition to contributing to the choice of antimicrobials and the most effective therapeutic strategies for the treatment of multi-resistant Corynebacterium sp.

ABSTRACT

A caprinocultura na região Nordeste do Brasil desempenha importante função socioeconômica e estratégica. A rusticidade desta atividade nesta região, aliada a sua rápida expansão em outros estados, tem gerado perdas na sua cadeia produtiva a nível regional e nacional, causadas por doenças infecciosas, destacando-se a Linfadenite Caseosa (LC), afecção amplamente difundida nos rebanhos caprinos, acarretando sérios prejuízos econômicos à atividade. Embora LC tenha sido detectada como um problema endêmico no nordeste brasileiro, uma análise abrangente e mais recente desta prevalência nos rebanhos caprinos brasileiros se faz necessária. O objetivo desse estudo foi determinar a frequência de anticorpos anti-Corynebacterium pseudotuberculosis em cinco dos nove estados que compõem a região Nordeste do Brasil. Foram processadas amostras de soro de 2571 caprinos provenientes de 218 propriedades rurais oriundas de cinco estados da região Nordeste do Brasil, coletadas entre os anos de 2010 a 2012. O diagnóstico da infecção por C. pseudotuberculosis foi realizado pela técnica de ELISA-indireto. Em 88,5% (193/218) das propriedades investigadas, pelo menos um caprino foi soropositivo para C. pseudotuberculosis, sugerindo que o agente se encontra disseminado nos rebanhos do Nordeste, com a maior prevalência encontrada no Rio Grande do Norte (94,5%) e a menor no estado de Sergipe (70,3%). Foram identificados 783 (30,4%; IC 95%=28,7-32,2%) caprinos soropositivos, com a maior prevalência entre animais encontrada no Piauí (41,4%) e a menor no estado de Sergipe (22,5%). De um total de 279 reprodutores avaliados, 106 (37,9%) resultaram soropositivos, destacando-se o Rio Grande do Norte, com 45,30%, e Piauí com 46,8% dos reprodutores positivos para LC. Das 1420 matrizes testadas, 599(42,1%) apresentaram sorologia positiva para C. pseudotuberculosis. Entre os estados esta distribuição também se manteve semelhante, destacando-se o Rio Grande do Norte, com 47,5% e Piauí com 59,5% das matrizes positivos para LC. Entre os 872 caprinos jovens avaliados, 78 (8,9%) foram soropositivos para LC, observando-se uma diferença estatística na frequência de sopositividade obtidas entre os adultos e os jovens (P<0,001). Reforça-se a necessidade do diagnóstico da enfermidade em rebanhos caprinos da região Nordeste para possível implementação de programas de controle da doença e medidas mais precisas no manejo da LC junto aos criadores de caprinos.(AU)


Goat farming in the Northeast region of Brazil plays an important socioeconomic and strategic role. The rusticity of this activity in this region, allied with its rapid expansion in other states, has caused losses in its production chain in regional and national levels, caused by infectious diseases, especially caseous lymphadenitis (CL), a widespread goat herds disease which has been causing serious economic loss to this activity. Although CL has been detected as an endemic problem in the Brazilian Northeast, a comprehensive and more recent analysis of this prevalence in Brazilian goats is necessary. The objective of this study was to determine the frequency of anti-Corynebacterium pseudotuberculosis antibodies in five of nine states of the northeast region of Brazil. Serum samples were collected from 2571 goats from 218 farms in five states in the Northeast region of Brazil, collected between 2010 and 2012. The diagnosis of C. pseudotuberculosis infection was made using the ELISA-indirect technique. In 88.5% (193/218) of the investigated properties, at least one goat was seropositive for C. pseudotuberculosis, suggesting that the agent is widespread in Northeast herds, with the highest prevalence found in Rio Grande do Norte (94.5%) and the lowest one in the state of Sergipe (70.3%). A total of 783 (30.45%; 95% CI = 28.71-32.26%) seropositive goats were found, and the highest prevalence among animals was found in Piauí (41.4%) and the lowest in the state of Sergipe (22.5%). Out of a total of 279 breeding herds, 106 (37.99%) were seropositive, standing out the Rio Grande do Norte, with a total of 45.30%, and Piauí 46.8% of positive breeding for CL. A total of the 1420 tested matrices, 599 (42.1%) presented positive serology for C. pseudotuberculosis. Among the States, this distribution also remained similar, standing out Rio Grande do Norte with 47.5%, and Piauí with 59.5% of positive matrices for CL. Among 872 young goats evaluated, 78 (8.9%) were seropositive for CL, observing a statistical difference in the frequency of soropositivity obtained between adults and young adults (P<0.001). The necessity to diagnose the disease in goat herds in the Northeast region is reinforced for the possible implementation of disease control programs and more precise measures to manage CL along with goat farmers.(AU)

ABSTRACT

Corynebacterium pseudodiphtheriticum forma parte de la microbiota normal de orofaringe y de piel. Sin embargo, en las últimas décadas está emergiendo como oportunista causante de infecciones clínicamente significativas en pacientes con algún compromiso previo. Se refiere el caso clínico de una paciente de 76 años con antecedentes de hipertensión arterial, hipotiroidismo, diabetes tipo 2 e insuficiencia renal crónica, que presentó neumonía durante su estadía en terapia intensiva. El examen directo del esputo inducido (coloración de Gram) reveló una muestra representativa con abundante microbiota monomicrobiana constituida por bacilos gram positivos pleomórficos corineformes y el cultivo presencia de C. pseudodiphtheriticum. La paciente recibió medicación empírica con cefalosporina de tercera generación con evolución favorable.


Microorganisms of the genera Corynebacterium, specie pseudodiphtheriticum are a part of the indigenous microbiota of human skin and oropharinx. Nevertheless in recent decades these bacilli are emerging as opportunistic pathogens causing clinically significant infections in patients with previous compromise. We report the case of a 76 years old female patient, with a history of hypertension, hypothyroidism, type 2 diabetes and chronic renal failure, who presented pneumonia during their stay at the intensive care unit. The induced sputum revealed a representative sample with monomicrobial gram positive pleomorphic coryneform rods (Gram stain) and cultures demonstrated the presence of C. pseudodiphtheriticum as the only bacteria recovered. The pacient received an empirical third generation cephalosporin medication with a succesfull recovery.

ABSTRACT

This paper reports the clinical, bacteriological and pathological findings of a thoracic aortic aneurysm in a four-year-old Anglo-Nubian goat buck, related to a framework of visceral caseous lymphadenitis. General clinical examination showed heart rate of 75 beats per minute, respiratory rate of 20 movements per minute and ruminal movements of four movements per minute. Superficial lymph nodes were normal upon palpation. Rectal temperature was slightly high (40.5°C). Blood test showed an intense leukocytosis (54,000/µL), characterized by strong neutrophil shift to the left. At necropsy, a large blood clot was detected in the thoracic cavity. The thickening of the myocardium and dilatation of the aorta in the thoracic portion, presenting a saculiform format was also observed. A large number of abscesses were disseminated in the media and intima layers of aorta. The aorta lumen obstruction by arterial plaques consisting of inflammatory infiltrate, predominantly neutrophilic was also detected. Abscesses were found spread in turbinate, rumen, reticulum, kidneys, liver, spleen, testicles and aorta wall. The microbiological exam of exudate confirmed Corynebacterium pseudotuberculosis as the causal agent.


Este trabalho descreve os achados clínicos, bacteriológicos e patológicos de um aneurisma da aorta torácica em um reprodutor caprino da raça Anglo-Nubiana, de quatro anos de idade, relacionado a um caso de linfadenite caseosa visceral. Ao exame clínico geral observaram-se: frequência cardíaca de 75 batimentos por minuto, frequência respiratória de 20 movimentos por minuto e movimentos ruminais de quatro movimentos por minuto. Os linfonodos superficiais encontravam-se normais à palpação. A temperatura retal estava ligeiramente aumentada (40,5°C). No hemograma completo, observou-se leucocitose intensa, 54.000/µL, caracterizada por um forte desvio neutrofílico à direita. Nos achados de necropsia, observou-se, na cavidade torácica, presença de um grande coágulo de sangue. No coração, foi identificado espessamento do miocárdio. Uma dilatação na porção torácica da artéria aorta foi detectada, apresentando um aspecto saculiforme. Um grande número de abscessos estava presente nas camadas média e íntima da aorta. Observou-se, também, obstrução do lúmen da aorta por placas de infiltrado inflamatório, predominantemente neutrofílico. A disseminação de abscessos nos cornetos, rúmen, retículo, fígado, baço, rins, testículos e parede da aorta foi detectada. O exame microbiológico do exsudato confirmou o Corynebacterium pseudotuberculosis como o agente causal.

ABSTRACT

The present work is a large epidemiological study aiming to detect the prevalence of subclinical mastitis and to investigate the major udder pathogens in Jalisco State, western Mexico. For this purpose, 2205 dairy cows, representing 33 Mexican dairy herds, were involved. Of 2205 cows, 752 mastitic animals were diagnosed and only 2,979 milk samples could be obtained for further investigation. All 2979 milk samples were subjected to California Mastitis Test (CMT) to differentiate clinical cases from subclinical ones where 1996 samples (67 %) reacted positively. Of these, 1087 samples (54.5%) came from cows suffering from clinical cases of mastitis. Bacteriological identification of the causative agents revealed the presence of a major group of pathogens including the Coagulase negative staphylococci (CNS), S.aureus, S.agalactiae, Corynebacterium spp. and Coliform bacteria which were detected in 464 (15.6%), 175 (5.9%), 200 (6.8%), 417 (14%) and 123 (4.1%) of the 2927 investigated quarters, 295 (15.4%), 118 (15.7%), 111 (14.8%), 227 (30.2%) and 109 (14.5%) of the 752 examined cows and in 33 (100%), 22 (66.7%), 19 (57.6%), 30 (90.1%) and 27 (81.8%) of the 33 herds involved, respectively. Other pathogens could be detected in the investigated milk samples such as S. dysgalactiae (0.4%), S.uberis (0.37%), Bacillus spp. (1%), Nocardia spp. (0.6%) und Candida spp. (0.1%). Meanwhile, others were present in a negligible ratio; including the Aerococcus viridans, and Enterococcus spp., Lactococcus lactis, S. bovis.


O trabalho atual é um estudo epidemiológico que objetiva detectar a predominância da mastite subclínica e investigar os micróbios patogênicos principais do úbere no México ocidental. Com esta finalidade, foram utilizadas 2205 vacas leiteiras, representando 33 rebanhos de leiteiras mexicanas. Além dessas 2205 vacas, 752 animais com mastite foram diagnosticados, considerando-se que somente 2979 amostras do leite poderiam ser obtidas para a posterior investigação. Todas as 2979 amostras do leite foram submetidas ao teste da mastite de Califórnia (CMT) para diferenciar casos clínicos dos subclínicos, visto que 1996 amostras (67%) reagiram positivamente. Além dessas, 1087 amostras (54.5%) vieram das vacas que sofrem de casos clínicos de mastite. A identificação bacteriológica dos agentes causais revelou a presença dos Staphylococcus negativos para coagulase (CNS), S. aureus, S. agalactiae, outros spp. Streptococcal, Corynebacterium spp., e as bactérias de coliformes foram detectadas em 464 (15.6%), 175 (5.9%), 200 (6.8%), 109 (3.9%), 417 (14%) e em 123 (4.1%) dos 2927 quartos investigados; em 295 (15.4%), 118 (15.7%), 111 (14.8%), 95 (12.6%), 227 (30.2%) e em 109 (14.5%) das 752 vacas examinadas e, finalmente, em 33 (100%), 22 (66.7%), 19 (57.6%), 30 (90.1%), 30 (90.1%) e em 27 (81.8%) dos 33 rebanhos envolvidos, respectivamente.

ABSTRACT

Corynebacterium pseudodiphtheriticum is a well-known human pathogen that mainly causes respiratory disease and is associated with high mortality in compromised hosts. Little is known about the virulence factors and pathogenesis of C. pseudodiphtheriticum. In this study, cultured human epithelial (HEp-2) cells were used to analyse the adherence pattern, internalisation and intracellular survival of the ATCC 10700 type strain and two additional clinical isolates. These microorganisms exhibited an aggregative adherence-like pattern to HEp-2 cells characterised by clumps of bacteria with a "stacked-brick" appearance. The differences in the ability of these microorganisms to invade and survive within HEp-2 cells and replicate in the extracellular environment up to 24 h post infection were evaluated. The fluorescent actin staining test demonstrated that actin polymerisation is involved in the internalisation of the C. pseudodiphtheriticum strains. The depolymerisation of microfilaments by cytochalasin E significantly reduced the internalisation of C. pseudodiphtheriticum by HEp-2 cells. Bacterial internalisation and cytoskeletal rearrangement seemed to be partially triggered by the activation of tyrosine kinase activity. Although C. pseudodiphtheriticum strains did not demonstrate an ability to replicate intracellularly, HEp-2 cells were unable to fully clear the pathogen within 24 h. These characteristics may explain how some C. pseudodiphtheriticum strains cause severe infection in human patients.

ABSTRACT

This study aimed to describe an outbreak of bovine mastitis caused by yeast in a dairy herd located in the state of Minas Gerais, Brazil. Microbiological analysis of milk samples (106) of the infected mammary quarters of lactating cows showed that Corynebacterium bovis (43.48%) and yeasts from the genus Candida (29.35%) were the main agents isolated in the herd. C. albicans(33.34%), C. catenulate (22.23%) and C. glabrata (18.52%) were the species most commonly isolated. The high prevalence of yeast mastitis was associated with lack of training formilkers, repetitive intramammary treatment and poor teat hygiene prior to the intramammary infusion. Appropriate management measures, specific treatment with antifungal drugs and removal of chronically infected animals were effective for the control of mastitis outbreak.


O objetivo deste estudo foi descrever um surto de mastite bovina causada por leveduras em um rebanho leiteiro localizado no Estado de Minas Gerais, Brasil. Análises microbiológicas de amostras de leite (106) dos quartos mamários infectados de vacas em lactação demonstraram que Corynebacterium bovis (43,48%) e leveduras do gênero Candida (29,35%) foram os principais agentes isolados no rebanho. C. albicans (33,34%), C. catenulata (22,23%) e C. glabrata (18,52%) foram as espécies mais comumente isoladas. A elevada prevalência da mastite por leveduras foi associada à falta de treinamento dos ordenhadores, ao tratamento intramamário repetitivo e a falhas na higienização de tetas antes da infusão intramamária. Medidas adequadas de manejo, tratamento específico com drogas antifúngicas e descarte de animais cronicamente infectados foram eficazes para o controle do surto.

ABSTRACT

Este trabalho teve como objetivo determinar a prevalência e distribuição de lesões da linfadenite caseosa em ovinos deslanados abatidos no município de Mulungu, Paraíba. Dos 1466 ovinos abatidos, 236 (15,9%) apresentaram lesões macroscópicas semelhantes à linfadenite caseosa. A prevalência foi maior em fêmeas, 17.9% (135/754) que em machos, 13,8% (101/732). As principais lesões estavam localizadas nos linfonodos pré-escapulares em 36,3% (97/268) dos ovinos, nos parotídeos em 22,4% (60/268) e no pré-crural em 20,9% (56/268). Somente 70 (26,1%) de um total de 268 lesões foram detectadas no exame ante mortem. Foram encontradas lesões em todos os lotes provenientes de diversos municípios da Paraíba, Pernambuco e Bahia. Das 51 amostras em que foi feito o cultivo bacteriológico, em 74,5% (43/51) foi isolado Corynebacterium pseudotuberculosis. Em 7,8% (4/51) foi isolado Staphylococcus aureus, em 2% (1/51) Escherichiacoli e 5,9% (3/51) amostras foram negativas. No exame histológico, em 11 linfonodos havia lesões da linfadenite caseosa caracterizadas por área de necrose central formada por lamelas concêntricas, com presença de grandes colônias bacterianas e focos de mineralização, rodeada por uma faixa de infiltrado inflamatório com macrófagos epitelióides e poucos neutrófilos. Na camada adjacente observaram-se linfócitos e plasmócitos e toda a lesão era delimitada por tecido conjuntivo fibroso. Nas outras 32 amostras foram observadas a maioria, mas não todas as lesões características da doença. Em 21 amostras foram encontradas células gigantes. As lesões histológicas dos linfonodos que foi isolado S. aureus foram semelhantes as da linfadenite caseosa. Conclui-se que as lesões histológicas de linfadenite caseosa são características, mas não patognomônicas, pois podem ser confundidas com lesões causadas por outros organismos piógenos e com tuberculose; portanto o isolamento bacteriológico é imprescindível para o diagnóstico definitivo da linfadenite caseosa.


The objective of this paper is to report the prevalence and distribution of lesions of caseous lymphadenitis (CL) in hair sheep slaughtered in an abattoir in the state of Paraíba, northeastern Brazil. From 1,466 sheep slaughtered, 236 (15.9%) had gross lesions similar to that of CL. The prevalence was higher in females, 17.9% (135/754), than in males, 13.8% (101/732). Ninety seven (36.3%) out of 268 lesions were localized in the prescapular lymph node, 22.4% (60/268) in the parotideal, and 20.9% (56/268) in the prefemoral. Only 70 (26.1%) out of 268 lesions suggestive of CL were detected during ante mortem examination. Caseous lymphadenitis-like lesions were observed in all flocks examined from different municipalities in the states of Paraíba, Pernambuco and Bahia. Cultures and histologic examination were performed in samples from 51 lesions. Corynebacterium pseudotuberculosis was isolated in 74.5% (43/51) samples, Staphylococcus aureus in 7.8% (4/51) samples, Escherichia coli in 2% (1/51), and in 5.9% (3/51) samples cultures were negative. Histologic findings in 11 lymph nodes showed all characteristic lesions of caseous lymphadenitis: central area of necrosis formed by concentric lamellae, with large bacterial colonies and mineralization, surrounded by an inflammatory exudate with epithelioid macrophages and few neutrophils; lymphocytes and plasma cells were observed in the next layer, and fibrous tissue was surrounding the whole lesion. Lesions in the other 32 lymph nodes showed most, but not all lesions characteristic of the disease. Giant cells were observed in 21 lymph nodes. Histologic lesions in lymph nodes from which S. aureus was isolated were similar as those of CL. These findings suggest that CL lesions are characteristic, but not pathognogmonic, because they can be confused with lesions caused by other pyogenic bacteria or tuberculosis; therefore bacteriologic examination is necessary for the diagnosis of the disease.

ABSTRACT

A total number of 2102 calves was examined raging in age from one day to nine months. Thirteen cattle and buffalo farms in different areas of Upper Egypt were visited regularly. The common umbilical affections were studied in relation to housing and breeding systems, breed, age, sex and other accompanying diseases. The results showed that umbilical masses should not be dealt with a simple entity, but the different possible etiological factors should be considered. Moreover, surgical intervention proved to be the ensured way to deal with cases of umbilical masses individually

ABSTRACT

Se estudiaron 196 niños escolares, 96 estudiantes de un grupo educativo ubicado en la Urbanización Prados del Este, que representó al nivel socio-económico alto, y 100 de una Unidad Escolar ubicada en la Urbanización Prado de María, que representó el nivel socio-económico bajo. Se demostró la presencia de Streptococcus pyogenes en el 11,0% de los niños escolares de bajo nivel socio-económico y en el 2,1% de los niños de nivel alto. Este germen fue encontrado más frecuentemente en el grupo de 7 a 10. Haemophilus influenzae se demostró en el 9% de los niños de bajo nivel socio-económico y en el 3,1% de los niños de alto nivel. Este germen fue más frecuente en el grupo de 7 a 10 años. Streptococcus pneumoniae se aisló con mayor frecuencia en el grupo de bajo nivel socio-económico y las enterobacterias en el grupo de 7 a 10 años. Staphylococcus aureus fue más frecuente en los escolares de bajo nivel socio-económico y en el grupo de 11 a 14 años. La mayor incidencia de patógenos específicos en la flora normal de la faringe, en niños de bajo nivel socio-económico, parece depender del hacinamiento y las malas condiciones higiénicas que rodean a este grupo de niños
