First identification of Angiostrongylus spp. in Lissachatina fulica and Cornu aspersum in Antioquia, Colombia / Identificación de Angiostrongylus spp. en Lissachatina fulica y Cornu aspersum en Antioquia, Colombia

Abstract Introduction. Abdominal and neural angiostrongyliasis caused by Angiostrongylus costaricensis and A. cantonensis, respectively, are zoonotic diseases involving snails as intermediate hosts. Colombia has already reported human cases, and the increasing distribution of Lissachatina fulica and Cornu aspersum raises public health concerns due to the potential risk of disease transmission in areas where parasites and hosts coexist. Objective. To identify the presence of Angiostrongylus spp. in snail species L. fulica and C. aspersum in Antioquia, Colombia. Materials and methods. This prospective cross-sectional study had a population of 5,855 L. fulica and C. aspersum snails captured in the ten towns of the Valle de Aburrá (Antioquia, Colombia), 169 samples were collected in 28 sampling points. Lung tissues of the collected snails were dissected and analyzed to detect Angiostrongylus spp. through molecular techniques. Results. Angiostrongylus spp. were identified in both L. fulica and C. aspersum. Angiostrongylus costaricensis was detected in 18 pooled prevalence of 30% (95% CI = 19.2-43.3), and Medellín was the municipality with the highest number of positive samples (33.3%). Seventy-two-point-two percent of the positive places reported the presence of rodents. None of the tests were positive for A. cantonensis. Conclusion. Our findings provide important insights into the epidemiology and distribution of Angiostrongylus spp. in Antioquia, Colombia. The identification of these parasitic nematodes in L. fulica and C. aspersum highlights the potential role of these snails as intermediate hosts in the transmission of Angiostrongylus spp. infections in the Valle de Aburrá, with implications for human and veterinary health.

An interesting case of dengue masquerading a splenic brucellosis

Mixed infections or co-infections are not uncommon in dengue fever which can occur as a result of transient suppression of host immunity by unknown mechanisms or as a part of its complication. Brucellosis co infection or post dengue complication can occur due to the indigenous practice of consumption of raw unpasteurized cattle milk. Here is a case report of a 14-year-old girl who presented with dengue fever but then continued to have persistence of fever spikes with abdominal pain requiring administration of antibiotics as well as upgradation, on evaluation was found to have splenic abscess with prior history of ingestion of raw goat抯 milk with serology suggestive of Brucellosis. This case report was done to elucidate the likelihood of co infection of zoonoses like dengue and brucellosis and the importance of consideration of brucellosis as a differential in cases of unresolving pyrexia post dengue fever especially in countries with wide prevalence of this practice of consumption of unpasteurized cattle milk.

A inserção da Medicina Veterinária em uma Residência Multiprofissional em Saúde da Família e Comunidade: um relato de experiência

Objetivou-se com o presente trabalho descrever a experiência vivenciada por residentes da Medicina Veterinária (MV) durante pandemia da COVID-19. Trata-se de um relato de experiência sobre a inserção de residentes da MV no Programa de Residência Multiprofissional em Saúde da Família e Comunidade (PRMSFC) na Atenção Básica (AB) do município de João Pessoa - PB, durante o período de março de 2021 a fevereiro de 2022. Os primeiros desafios encontrados foram atividades concentradas em consultas, testagens e vacinações, e a falta de informação sobre o trabalho da MV. Os territórios das Unidades de Saúde da Família (USF) caracterizaram-se por áreas com desmatamento, urbanização, falta de saneamento básico, acúmulo de lixo, presença de animais de rua, agrícolas, sinantrópicos e peçonhentos. Nas USF foram observados casos de diversas zoonoses, como esporotricose, toxoplasmose e acidentes com animais peçonhentos. Foram realizadas ações de educação em saúde e articulações com outros serviços. Alguns problemas que limitaram a inserção da MV foram ausência de médicos veterinários na AB, dificuldades com a preceptoria e AB centrada no atendimento ambulatorial. A presença da MV na AB mostrou-se importante para o diagnóstico, notificação, promoção e prevenção em saúde de doenças e agravos da interface ambiente-animal-ser humano.

Vigilância participativa: caminhos para a Saúde Única no Pantanal e na fronteira oeste / Participatory surveillance: paths to One Health in the Pantanal and the western border

RESUMO O projeto 'Saúde Única no Pantanal: participação da sociedade na vigilância de emergência de zoonoses como efeito pós-incêndios no território e formação de estratégias integradas' objetivou integrar representações institucionais e da sociedade local; ampliar o uso do Sistema de Informação em Saúde Silvestre (SISS-Geo) para o monitoramento da fauna; identificar áreas prioritárias para vigilância de zoonoses e construir caminhos envolvendo a Saúde Única (SU). Realizou webinário, apontando a necessidade de eventos mais amplos com a participação de lideranças em cada um dos territórios escolhidos. Foram executados seminários e oficinas nos estados de Mato Grosso do Sul (MS), com a participação de gestores do serviço de saúde da Província de Santa Cruz, Bolívia, e de Mato Grosso. A representatividade dos diferentes segmentos nos eventos possibilitou a articulação de cidadãos e gestores locais. Nas comunidades tradicionais, foi possível abordar os impactos dos incêndios e dar oportunidade para que essas pessoas manifestassem suas prioridades e demandas de saúde, antes e depois dos incêndios. A Oficina Síntese realizada em Corumbá, MS possibilitou a devolutiva dos resultados e a integração com representantes de diferentes instituições do Brasil e da Bolívia, além da prospecção e priorização de enfermidades a serem incorporadas em modelo de SU para o Pantanal e fronteira oeste do Brasil.

ABSTRACT The project 'One Health in the Pantanal: society's participation in the emergency surveillance of zoonoses emergency as a post-fire effect in the territory and the formation of integrated strategies' aimed to integrate institutional representations and local society; expand the use of Wildlife Health Information System (SISS-Geo) for fauna monitoring; identify priority areas for zoonosis surveillance and build paths involving One Health (OH). A webinar was held, highlighting the need for broader events with the participation of leaders in each of the chosen territories. Seminars and workshops were held in the states of Mato Grosso do Sul (MS), with the participation of health service managers from the Province of Santa Cruz, Bolivia, and Mato Grosso. The representation of different segments at the events enabled the articulation of citizens and local managers. In traditional communities, it was possible to address the impacts of the fires and provide the opportunity for these people to express their health priorities and demands, before and after the fires. The Synthesis Workshop held in Corumbá, MS allowed the feedback of results and integration with representatives from different institutions in Brazil and Bolivia, and prospecting and prioritization of illnesses to be incorporated into the OH model for the Pantanal and western border of Brazil.

Deforestation increases the abundance of rodents and their ectoparasites in the Lacandon forest, Southern Mexico

Introduction: Tropical forests provide important ecosystem services, including disease control. However, few studies have focused on how deforestation affects species more suitable to be zoonotic vectors. Objective: To evaluate how deforestation affects the abundance and species richness of rodents and their associated ectoparasites in a tropical ecosystem. Methods: We captured rodents in 6 landscape units, 1 km² each, with 0.7; 5; 40; 46; 78 and 95 % tree cover, in Marques de Comillas, Chiapas, Southern Mexico. In each unit we set 90 Sherman traps that were active 24 hours for 7 days during two sampling seasons (October 2019, and September 2020). We manually extracted ectoparasites from all captured rodents. Results: We captured 70 rodents of five species: Sigmodon toltecus, Heteromys desmarestianus, Ototylomys phyllotis, Peromyscus mexicanus, and Oryzomys couesi. Rodent abundance increased with forest loss (R²= 0.706, P= 0.022). The greatest richness of rodent species occurred in sites with intermediate forest cover (40 and 78 %). The most abundant species were: S. toltecus (N= 45) followed by O. couesi (N= 9), these species dominated in sites with less forest cover. We recorded a total of 23 ectoparasite species, three of them known to be zoonotic vectors: Amblyomma sp., Ornithonyssus bacoti, and Androlaelaps fahrenholzi. Conclusions: The ongoing loss of forests promotes the proliferation of zoonotic disease vectors in this tropical ecosystem, which can potentially increase the frequency of affectation among the local population.

Introducción: Un servicio particularmente importante que brindan los bosques tropicales es el control de enfermedades. Sin embargo, pocos estudios se han enfocado en analizar cómo este servicio es afectado por la deforestación. Objetivo: Evaluar el efecto de la deforestación en la abundancia y riqueza de especies de roedores y de sus ectoparásitos en Marqués de Comillas, en el sureste de México. Métodos: Capturamos roedores en 6 unidades del paisaje (UP), cada una de 1 km², con distintos porcentajes de cobertura vegetal (0.7, 5, 40, 46, 78 y 95 %). En cada UP colocamos 90 trampas Sherman, que permanecieron activas las 24 horas por 7 días durante dos muestreos en octubre 2019 y septiembre 2020. Todos los roedores capturados fueron revisados para detectar ectoparásitos en su pelaje que fueron recolectados para su posterior identificación en el laboratorio. Resultados: Capturamos 70 roedores de cinco especies: Sigmodon toltecus, Heteromys desmarestianus, Ototylomys phyllotis, Peromyscus mexicanus y Oryzomys couesi. La abundancia de roedores aumentó con la pérdida de bosque (R² = 0.706, P = 0.022). La mayor riqueza de especies de roedores se presentó en sitios con cobertura forestal intermedia (40 y 78 %). Las especies más abundantes fueron: S. toltecus (N = 45) seguido de O. couesi (N = 9), estas especies dominaron en los sitios con menor cobertura forestal. Registramos un total de 23 ectoparásitos diferentes, identificamos 15 a nivel de especie y ocho a nivel de género. Los sitios con menor cobertura forestal presentaron la menor riqueza de especies de ectoparásitos. Detectamos tres especies de ectoparásitos (Amblyomma sp., Ornithonyssus bacoti y Androlaelaps fahrenholzi) que se sabe que son vectores de enfermedades zoonóticas. Conclusión: Encontramos que la deforestación está promoviendo un aumento en la proliferación de vectores de enfermedades zoonóticas lo que, a su vez, tiene el potencial de incrementar las afectaciones de la población local.

Prevalencia de parásitos intestinales en niños y animales domésticos en dos barrios periurbanos del nordeste de Argentina / Prevalence of intestinal parasites in children and domestic animals from two peri-urban neighborhoods in northeastern Argentina

RESUMEN El objetivo de este estudio fue examinar la prevalencia de parásitos intestinales de niños y animales domésticos en dos barrios periurbanos de la ciudad de Corrientes, Argentina. También evaluamos las características de los humanos, factores socio-ambientales y prácticas de higiene asociadas con la presencia de parásitos. Las muestras fecales fueron examinadas usando técnicas de concentración por sedimentación y flotación. Se detectaron huevos de Enterobius vermicularis en niños utilizando el método de Graham. El análisis de los datos fue univariado y bivariado. En total, 58 viviendas fueron evaluadas, de las cuales se obtuvieron 146 muestras de heces de niños y 101 muestras de animales. Se registró al menos una especie de parásito en 54 viviendas (93,1%). Encontramos parásitos en el 52,7% de los niños, principalmente los protozoos Blastocystis spp. (35,6%) y Giardia spp. (21,2%). Se detectaron parásitos en 67,32% de los animales, principalmente ancilostomídeos (60,7%). En conclusión, es evidente que el ambiente doméstico presenta condiciones favorables para la transmisión de estos parásitos.

ABSTRACT This study aimed to examine the prevalence of intestinal parasites in children and domestic animals from two peri-urban neighborhoods in Corrientes, Argentina. We also evaluated the characteristics of humans, socio-environmental features, and hygiene practices associated with the presence of parasites. Fecal samples were examined using techniques of concentration by sedimentation and flotation. The Graham method was used to diagnose Enterobius vermicularis eggs in children. We carried out the univariate and bivariate analysis of the data. We analyzed 58 dwellings, from which we obtained 146 stool samples from children and 101 from animals. We found at least one parasite species in 54 dwellings (93.1%). We found that 52.7% of children had parasites, mainly Blastocystis spp. (35.6%) and Giardia spp. (21.2%). We found that 67.32% of the animals had parasites, the most prevalent species being hookworms (60.7%). In conclusion, it is evident that the domestic environment can favor the transmission of these parasites.

Acute Febrile Syndrome in an endemic region of Colombia: What is there beyond Dengue? / Síndrome Febril Agudo en una región endémica de Colombia: ¿Qué hay más allá del Dengue?

Abstract Objective: Evaluate the presence of alternative diagnoses in patients presenting with Acute Febrile Syndrome (AFS) and a negative Dengue IgM test. Methods: A retrospective descriptive study of the clinical records of patients who presented to the emergency department of ESE Hospital Universitario San Jorge from Pereira, Colombia with Dengue-like Acute Febrile Syndrome between January 2014 and December 2017. Results: 561 patients attending to the emergency department of a third level care and referral center in Pereira, Colombia with a Dengue-like Acute Febrile Syndrome. One hundred thirty three (23.7%) patients were included in the analysis. The three most common alternative diagnoses were leptospirosis (7.5%), malaria (3.8%) and bacterial bloodstream infection (2.3%). The main AFS presentations were hemorrhagic (34.6%), exanthematic (21.1%) and undifferentiated (21.1%). A statistically significant proportion were from rural origin and coursed with anemia, leukocytosis, hyperbilirrubinemia, icterohemorrhagic and icteric AFS. Acute kidney injury with serum creatinine >2 mg/dl and blood urea nitrogen >25 mg/dl were associated with the finding of an alternative diagnosis. Conclusions: The low rate of definitive diagnosis, the low request of tests to exclude Malaria, and the significant proportion of Dengue IgM tests requested within the first 4 days of fever, suggests the need to evaluate clinical practice. Training the Emergency Department personnel in the recognition of Acute Febrile Syndrome, as well as the development of prospective investigations, could lead to improvement in the quality of attention, the outcomes, and higher rates of diagnosis.

Resumen Objetivo: evaluar la presencia de diagnósticos alternativos en pacientes con Síndrome Febril Agudo y prueba IgM negativa para Dengue. Métodos: estudio descriptivo retrospectivo de las historias clínicas de los pacientes que se presentaron al servicio de urgencias de la ESE Hospital Universitario San Jorge de Pereira con Síndrome Febril Agudo similar al Dengue entre enero de 2014 y diciembre de 2017. Resultados: 561 pacientes acudieron al servicio de urgencias con un Síndrome Febril Agudo similar a Dengue. 133 (23,7 %) pacientes fueron analizados. Las tres causas más comunes fueron Leptospirosis (7,5 %), Malaria (3,8 %) y Bacteremia (2,3 %). Las tres presentaciones clínicas más frecuentes de Síndrome Febril Agudo fueron: hemorrágico (34,6 %), exantemático (21,1 %) e indiferenciado (21,1 %). Una proporción significativa fue de procedencia rural y cursó con anemia, leucocitosis, hiperbilirrubinemia y síndromes icterohemorrágico e ictérico. La presencia de falla renal aguda con creatinina mayor a 2 mg/dl y nitrógeno ureico en sangre mayor a 25 mg/dl se asociaron con el hallazgo de un diagnóstico alternativo. Conclusiones: la baja tasa de diagnóstico definitivo, la baja solicitud de pruebas para excluir malaria, y la gran proporción de pacientes con solicitud de prueba para Dengue dentro de los primeros cinco días de fiebre demuestra la necesidad de revisar la práctica clínica. El entrenamiento del personal del servicio de urgencias en el reconocimiento del Síndrome Febril Agudo, al igual que la realización de investigaciones prospectivas pueden llevar a mejorar la calidad de atención, los desenlaces y mayores tasas de diagnóstico.

Equinococosis quística peritoneal diseminada en paciente con infección Por VIH: reporte de caso / Disseminated peritoneal cystic Echinococcosis in a patient with HIV: case report

RESUMEN La equinococosis quística es una infección zoonótica producida por la larva de Echinococcus granulosus que es capaz de invadir diversos órganos desde su ubicación en el intestino humano. En los casos de coinfección con el virus de la inmunodeficiencia humana (VIH), existe una diversidad de complicaciones condicionadas por la enfermedad inmunosupresora con pronóstico reservado. El objetivo de este reporte es describir un caso de equinococosis multiquística peritoneal en una paciente en tratamiento antiviral para VIH durante casi diez años, que recibió la combinación de albendazol más cirugía, con evolución favorable. Este reporte sería el primero en el Perú en una persona con inmunosupresión por VIH y equinococosis quística.

ABSTRACT Cystic echinococcosis is a zoonotic infection caused by the larva of Echinococcus granulosus, which is capable of invading several organs starting from the human intestine. There are several complications in cases of co-infection with the human immunodeficiency virus (HIV), which are conditioned by the immunosuppressive disease and have poor prognosis. This report aims to describe a case of multi-cystic peritoneal echinococcosis in a patient under antiviral treatment for HIV for almost ten years, who received albendazole, underwent surgery and progressed favorably. This would be the first Peruvian report of a person with HIV and cystic echinococcosis.

RESUMEN Objetivos. Determinar la seropositividad a anticuerpos anti-IgG por infección de Echinococcus granulosus, Fasciola hepatica y cisticerco de Taenia solium y describir las características de los infectados en 13 regiones de la sierra peruana entre 2016 y 2019. Materiales y métodos. Estudio observacional transversal, que analizó 7811 fichas epidemiológicas de la vigilancia basada en laboratorio de las zoonosis parasitarias del periodo 2016-2019. El diagnóstico se realizó mediante la detección de anticuerpos tipo IgG anti E. granulosus, F. hepatica y cisticerco de T. solium utilizando antígenos nativos mediante el ensayo inmunoabsorbente ligado a enzimas (ELISA) e Inmunoblot. La diferencia en la frecuencia de casos de estas zoonosis según características identificadas se realizó mediante la prueba chi-cuadrado de Pearson y prueba exacta de Fisher. Resultados. Se determinó una seropositividad de 7,9% para fascioliasis, 4,9% para equinococosis quística, y 2,3% para cisticerco de T. solium. Estas frecuencias fueron mayores en Cerro de Pasco para equinococosis quística (24,5%), en Ayacucho para cisticerco de T. solium (4,5%) y en Puno para fascioliasis (40,6%). Entre las características sociodemográficas, se encontró una diferencia estadísticamente significativa en la frecuencia de casos para todas las zoonosis según grupo etario, ocupación, y región de residencia. Además, se encontró diferencia con el consumo de verduras en emolientes, y entre las características clínico-epidemiológicas con tener antecedentes familiares de las zoonosis parasitarias. Conclusiones. A partir de las 7811 muestras evaluadas, se encontró que estas zoonosis parasitarias están distribuidas en 13 regiones de la sierra del Perú, ocasionando un problema de salud importante, con frecuencias que varían según diversas características.

ABSTRACT Objectives. To determine seropositivity to anti-IgG antibodies against Echinococcus granulosus, Fasciola hepatica and Taenia solium cysticercus infection and to describe the characteristics of the infected patients in 13 regions of the Peruvian highlands between 2016 and 2019. Materials and methods. Cross-sectional, observational study, in which we analyzed 7811 epidemiological records of laboratory-based surveillance of parasitic zoonoses from 2016 to 2019. Diagnosis was established by detecting IgG type anti-E. granulosus, F. hepatica and T. solium cysticercus antibodies using native antigens by enzyme-linked immunosorbent assay (ELISA) and Immunoblot. We evaluated the difference in the frequency of the cases according to identified characteristics using Pearson's chi-square test and Fisher's exact test. Results. Seropositivity was 7.9% for fascioliasis, 4.9% for cystic echinococcosis, and 2.3% for T. solium cysticercus. These rates were higher in Cerro de Pasco for cystic echinococcosis (24.5%), in Ayacucho for T. solium cysticercus (4.5%) and in Puno for fascioliasis (40.6%). Regarding the sociodemographic characteristics, we found a statistically significant difference in the frequency of cases for all zoonoses according to age group, occupation, and region of residence. We also found a difference with the consumption of vegetables in emollients, and between clinical-epidemiological characteristics and having a family history of parasitic zoonoses. Conclusions. From the 7811 samples, we found that these parasitic zoonoses are distributed in 13 regions of the Peruvian highlands, and represent a major health problem, with frequencies that change according to different characteristics.

Resumo Introdução A febre maculosa é uma doença infecciosa aguda causada por bactérias do gênero Rickettsia e transmitida por carrapatos que pode levar à hospitalização e, eventualmente, a óbito por causa de quadros mais graves. Objetivo O objetivo deste artigo foi descrever o cenário epidemiológico da doença nas três unidades federativas de maior número de notificações e óbitos pela doença no Brasil entre 2007 e 2016. Método Estudo epidemiológico descritivo com base nos dados das fichas de investigação para a doença, sendo analisados dados demográficos, geográficos, ambientais e de hospitalização, diagnóstico e desfecho dos casos na área de estudo. Resultados Foram confirmados 953 casos da doença, em sua maioria por critérios laboratoriais, sendo observada maior prevalência entre homens com idade média de 35 anos, pouco relacionados ao ambiente de trabalho, mas amplamente relacionados ao meio urbano. Do total de casos confirmados, 64% pacientes afirmaram ter tido algum contato com carrapato, assim como com cães (36%), capivaras (20%) e equinos (19%). Conclusão Existem questionamentos a respeito da doença que não foram elucidados neste artigo, entretanto abordagens criativas, validadas e ancoradas na associação de áreas de conhecimento distintas poderão dar bons resultados se objetivamente aplicadas em ações estratégicas da gestão da saúde.

Abstract Background Spotted fever is an acute infectious disease caused by bacteria of the genus Rickettsia and transmitted by ticks, which can lead to hospitalization and, eventually, death due to more severe conditions. Objective The purpose of this article was to describe the epidemiological scenario of the disease in the three federal states with the highest number of notifications and deaths due to the disease in Brazil between 2007 and 2016. Method A descriptive epidemiological study was carried out based on data from the investigation forms for the disease, with data being analyzed on demographic, geographic, environmental, and hospitalization, diagnosis, and outcome of cases in the study area. Results 953 cases of the disease were confirmed, mostly by laboratory criteria, with a higher prevalence being observed among men with an average age of 35 years, little related to the work environment, but largely related to the urban environment. Of the total confirmed cases, 64% of patients said that they had had some contact with ticks, as well as with dogs (36%), capybaras (20%), and horses (19%). Conclusion We believe that there are questions about the disease that were not elucidated in this article, however, creative approaches, validated and anchored in the association of different areas of knowledge can give good results if objectively applied in strategic health management actions.

Appraising epidemiology data and antimicrobial resistance of urinary tract infections in critically ill adult patients: a 7-year retrospective study in a referral Brazilian hospital

ABSTRACT BACKGROUND: Urinary tract infections (UTI) are highly preventable and have significant clinical and financial impact on the patient and the health care system. OBJECTIVE: To investigate UTIs in critically ill adult patients and the relationship of antimicrobial consumption and multidrug-resistant isolate. DESIGN AND SETTING: A cohort study performed in a Brazilian tertiary-care university hospital in the city of Uberlandia (MG), located at the Federal University of Uberlandia, southeast region of the country. METHODS: We analyzed a cohort of 363 patients with first episode of UTIs from the adult intensive care unit (ICU), from January 2012 to December 2018. The daily doses of antimicrobial administered were calculated. RESULTS: The incidence rate of UTI was 7.2/1000 patient days, with 3.5/1000 patient-days of bacteriuria, and 2.1/1000 patient-days of candiduria. Of 373 microorganisms identified, 69 (18.4%) were Gram-positive cocci, 190 (50.9%) Gram-negative bacilli, and 114 yeasts (30.7%). Escherichia coli and Candida spp. were the most common. Patients with candiduria had higher comorbidity score (Charlson Comorbidity Index ≥ 3), longer length of stay (P = 0.0066), higher mortality (P = < 0.0001) severe sepsis, septic shock, and were immunocompromised when compared with patients with bacteriuria. We observed correlation between antibiotics consumption and multidrug-resistant (MDR) microorganisms. CONCLUSION: The UTIs incidence was high and was mainly caused by Gram-negative bacteria that were resistant to common antibiotics. We observed increase in the consumption of broad-spectrum antibiotics in ICU correlating with MDR microorganisms. In general, ICU-acquired candiduria may be associated with critical illness and poor prognosis.

Associação entre determinantes em saúde e ocorrência de casos humanos de leptospirose em Minas Gerais: um estudo ecológico 2010-2019 / Association between health determinants and the occurrence of human cases of leptospirosis in Minas Gerais: an ecological study 2010-2019

Introdução: A leptospirose é considerada um problema de saúde pública com grande impacto social e econômico. A doença foi citada como duplamente omissa, uma vez já classificada na literatura internacional como doença tropical negligenciada (DTN), ainda conta com a baixa atenção governamental. Tal fato, pode estar associado ao adoecimento por essa enfermidade atingir majoritariamente a porção pobre e marginalizada da sociedade. Objetivos: O presente estudo objetiva avaliar a associação entre determinantes em saúde e adoecimento por leptospirose nos municípios do estado de Minas Gerais no período de 2010 a 2019. Metodologia: Trata-se de um estudo ecológico, no qual as unidades de análise foram os 853 municípios do estado de Minas Gerais. Foram utilizados dados secundários agregados não nominais entre os anos de 2010 e 2019. Foi utilizado o Modelo Binomial Negativo com Inflação de Zeros como técnica de análise multivariada, considerando a incidência por leptospirose em 2016 como desfecho e os indicadores do Índice Mineiro de Responsabilidade Social de 2016 ou em data mais próxima disponível como variáveis explicativas Resultados: Os resultados do modelo múltiplo demonstraram que os fatores que permaneceram associados à incidência de leptospirose foram os índices de Saúde, Educação, Renda e Emprego e a variável Infraestrutura Urbana. Segundo os coeficientes estimados, o índice de saúde do IMRS foi associado a um aumento da incidência de leptospirose. Por outro lado, os demais fatores ­ índice de educação, renda e emprego e a variável infraestrutura urbana ­ estiveram associados a menores taxas da doença, agindo assim, como fatores de proteção ao adoecimento. Conclusão: Há uma forte associação da leptospirose com a pobreza no estado de Minas Gerais. O investimento em infraestrutura urbana e garantia de condições sanitárias favoráveis para a população, bem como melhora da propagação de informação e educação reduziria o impacto da doença na população pobre e desassistida.

Introduction: Leptospirosis is considered a public health problem with great social and economic impact. The disease was cited as doubly omitted, since it is already classified in the international literature as a neglected tropical disease (NTD), it still has low government attention. This fact may be associated with the illness caused by this disease, which mostly affects the poor and marginalized portion of society. Objectives: This study aims to evaluate the association between health determinants and the illness from leptospirosis in the municipalities of the state of Minas Gerais from 2010 to 2019. Methodology: This is an ecological study and the units of analysis were the 853 municipalities in the state of Minas Gerais. Non-nominal aggregated secondary data between the years 2010 and 2019 were used. The Negative Binomial Model with Zero Inflation was used as a multivariate analysis technique, considering the incidence of leptospirosis in 2016 as the outcome and the IMRS indicators of 2016 or on a date closest available as explanatory variables Results: The results of the multiple model showed that the factors that remained associated with the incidence of leptospirosis were the Health, Education, Income and Employment indexes and the Urban Infrastructure variable. According to the estimated coefficients, the IMRS health index was associated with an increased incidence of leptospirosis. On the other hand, the other factors ­ education, income and employment index and the urban infrastructure variable ­ were associated with lower rates of the disease, thus acting as protective factors against illness. Conclusion: There is a strong association between leptospirosis and poverty in the state of Minas Gerais. Investment in urban infrastructure and guaranteeing favorable sanitary conditions for the population, as well as improving the dissemination of information and education would reduce the impact of the disease on the poor and underserved population.

Detection of Bartonella bovis DNA in blood samples from a veterinarian in Mexico

ABSTRACT The genus Bartonella encompasses 38 validated species of Gram-negative, facultative intracellular bacteria that colonize the endothelial cells and erythrocytes of a wide spectrum of mammals. To date, 12 Bartonella species have been recorded infecting humans, causing diseases of long historical characterization, such as cat scratch fever and trench fever, and emerging bartonellosis that mainly affect animal health professionals. For this reason, this study aimed to report a documented case of Bartonella bovis infecting a veterinarian from Mexico by the amplification, sequencing and phylogenetic reconstruction of the citrate synthase (gltA) and the RNA polymerase beta-subunit (rpoB) genes, and to report the natural course of this infection. To our knowledge, this work is the first to report the transmission of B. bovis via needlestick transmission to animal health workers in Latin America.
