Cysticercosis in free-ranging agoutis (Dasyprocta leporina) in the Eastern Brazilian Amazon.

The study describes the occurrence of cysticercosis in liver of 22 wild agoutis (Dasyprocta leporina) in the Brazilian Amazon. The phylogenetic analysis and microscopic characteristics of metacestodes in liver tissue sections, associated with the geographic distribution of the intermediate hosts indicated that a possibly novel Taenia sp. metacestode caused the parasitism. Additionally, two cases of hepatic co-infection by Taenia sp., Calodium sp. and Echinococcus oligarthra were also observed among the analyzed animals. The results point to the need for a better understanding of hepatotropic parasites among wild rodents in the Brazilian Amazon.

Survey of euthanasia methods used in neotropical chiropterans in São Paulo State, Brazil: critical analyses and proposal for standardization of bat euthanasia methods / evantamento dos métodos de eutanásia utilizados em quirópteros neotropicais no estado de São Paulo, Brasil: análise crítica e proposta de padronização de métodos de eutanásia em morcegos

Zoonotic Surveillance Divisions (ZSDs) rescue and euthanize bats in contact with humans. The euthanasia procedure should be conducted safely for the animal and caretaker and minimal stress for the animal is important. The objectives of this study were: i. evaluate the methods of euthanasia used by ZSDs in the State of São Paulo; ii. compare the methods with national and international guidelines for animal euthanasia practices; iii. assess the methodologies considering taxonomy and eating habits of the main bat species, and iv. propose standardization of euthanasia procedures. Sixty-five ZSDs locations received an online questionnaire or were contacted by telephone and 33 ZSDs (50.8%) responded and are distributed in 11 mesoregions in the state to remain anonymous. The euthanasia methods were divided into chemical (injectable or inhalation), physical, or mixed methods. Bat specimens (n = 550) were identified and classified to evaluate the main genera found in the state. The location of the ZSD, species, eating habits, and the method of euthanasia used were analyzed. The specimens by bat families were Molossidae (n = 340), Phyllostomidae (n = 171), and Vespertilionidae (n = 39). Chemical methods were used in 25 ZSDs (75.75%), physical in 5 (15.15%), and mixed in 3 (9.09%). There is no uniformity or standardization in bat euthanasia methods used by ZSDs, although most are based on acceptable chemical methods. It was proposed an algorithm to assist the veterinarian in choosing the method of euthanasia for bats that will allow standardizing euthanasia procedures for this species, considering physiological differences, and respecting technical, bioethical, and animal welfare guidelines.(AU)

As Divisões de Vigilância de Zoonoses (DVZs) coletam e eutanasiam morcegos que tiveram contato com humanos. O procedimento de eutanásia precisa ocorrer de modo seguro para o animal e para o manipulador, sendo importante garantir o mínimo de estresse ao animal. Os objetivos deste estudo foram: i. avaliar os métodos de eutanásia praticados nas DVZ do estado de São Paulo; ii. comparar esses métodos com os guias nacionais e internacionais de práticas de eutanásia animal; iii. avaliar as metodologias aplicadas considerando a taxonomia e os hábitos alimentares das principais espécies de ocorrência de morcegos; e iv. propor a padronização dos procedimentos de eutanásia. Sessenta e cinco DVZs receberam o questionário online ou foram contatadas por telefone, dessas, trinta e três DVZs (50,8%) que responderam ao questionário foram incluídas no estudo e distribuídas em 11 mesorregiões para garantir anonimato. Os métodos de eutanásia reportados foram divididos em métodos químicos (injetáveis; inalatórios), físicos ou mistos. Os espécimes de morcegos (n = 550) foram identificados e classificados para avaliar os principais gêneros encontrados no estado. A localização da DVZ, as espécies, os hábitos alimentares e o método de eutanásia utilizado foram analisados. Os espécimes por família de espécies de morcegos foram Molossidae (n = 340), Phyllostomidae (n = 171) e Vespertilionidae (n = 39). Métodos químicos foram utilizados em 25 DVZs (75,75%), físicos em 5 (15,15%) e mistos em 3 (9,09%). Não há uniformidade ou padronização nos métodos de eutanásia de morcegos, embora a maioria seja baseada em métodos químicos aceitáveis. É proposto um algoritmo para auxiliar o veterinário na escolha do método de eutanásia, que permite a padronização desses procedimentos para os morcegos, considerando as diferenças fisiológicas e respeitando as diretrizes técnicas, bioéticas e de bem-estar animal.(AU)

Serological and molecular retrospective analysis of hepatitis E suspected cases from the Eastern Brazilian Amazon 1993-2014.

INTRODUCTION: We evaluated the anti-hepatitis E virus (HEV) antibody prevalence and HEV-RNA in archived serum samples of non-A-C hepatitis, or suspected cases of HEV infection from the Eastern Brazilian Amazon from 1993 to 2014. METHODS: Serum samples (n = 318) were tested using ELISA and immunoblotting, and screened for HEV-RNA by RT-qPCR. RESULTS: Anti-HEV IgM and IgG were detected in 3.4% (11/318) and 5.9% (19/318) of the samples, respectively. All samples were HEV-RNA negative. CONCLUSIONS: HEV was detected at a low prevalence. Broader serological and molecular evaluation of HEV infection in the Amazon region should be carried out.
