Paracoccidioides brasiliensis infection in dogs from Western Brazilian Amazon. Pesquisa Veterinária Brasileira 32(7):649-652. Departamento de Ciências Patológicas, Universidade Estadual de Londrina, Londrina, PR 86051-980, Brazil. E-mail: marioono@uel.br The objective of the study was to evaluate Paracoccidioides brasiliensis infection in urban dogs from the municipality of Monte Negro, Rondonia, Western Brazilian Amazon. The serum samples (n=126) were analyzed by indirect ELISA and the immunodiffusion test using P. brasiliensis gp43 and exoantigen as antigens, respectively. A positivity of 54.8% was observed only in the ELISA test and no statistical difference was observed in the seroprevalence in relation to age or sex. This is the first paracoccidioidomycosis survey carried out with dogs from the Western Brazilian Amazon. The higher positivity rates of P. brasiliensis infection observed in this study suggest that veterinarians must be alert to detect new cases of natural disease in dogs living in paracoccidioidomycosis endemic areas.

RESUMO.- Corte A.C., Gennari S.M., Labruna M.B., Camargo L.M.A., Itano E.N., Freire R.L., Camargo Z.P. & Ono M.A. 2012. Paracoccidioides brasiliensis infection in dogs from Western Brazilian Amazon.

E-mail: marioono@uel.br O objetivo deste estudo foi avaliar a infecção por Paracoccidioides brasiliensis em cães urbanos do município de Monte Negro, Rondônia, Amazônia Ocidental Brasileira. As amostras de soro (n=126) foram analisadas por meio dos testes de ELISA indireto e imunodifusão utilizando gp43 de P. brasiliensis e exoantígeno como antígenos, respectivamente. Uma positividade de 54,8% foi observada apé isso mesmoenas no teste de ELISA e nenhuma diferença estatística foi observada na soroprevalência em relação ao sexo ou à idade. Este é o primeiro estudo epidemiológico de paracoccidioidomicose realizado com cães da Amazônia Ocidental Brasileira. A alta positividade de infecção por P. brasiliensis observada neste estudo sugere que os veterinários devem estar atentos para detectar a doença natural em cães de áreas endêmicas para paracoccidioidomicose.

Prof. Orlando Marques de Paiva 87, São Paulo, SP 05508-900, Brazil. E-mail: danmoura@aptaregional.sp.gov.br The prevalence of anti-Leptospira spp antibodies was investigated in 2,109 female cattle from 86 herds of Monte Negro municipality, Rondônia, Brazil. Sera samples were evaluated by Microscopic Agglutination Test against 24 leptospira serovars. Titers =100 for at least one of 24 leptospira serovars were detected in 1,114 cows (52.8%) from 82 (95.3%) herds. The adjusted overall prevalence for Monte Negro municipality was 53.9% (49-58.7%; CI: 95%). The most prevalent serovars were Hardjo (14.5%), Wolffi (12.3%), Shermani (10.8%), Patoc (7.9%), and Hebdomadis (6.1%). Other serovars worldwidely reported like Bratislava, Pomona and Grippotyphosa were detected in low levels.
