ABSTRACT

Abstract Leishmania spp. are important agents of human and animal leishmaniases that have an important impact on public health. In this study, we aimed to detect the circulation of Leishmania spp. in cattle from a visceral leishmaniasis non-endemic area of the state of São Paulo, Brazil. DNA was extracted from blood samples from 100 heifers in the municipality of Pirassununga and was amplified using primers specific for the first internal transcriber spacer (ITS1), to assess the presence of trypanosomatids. The assays revealed that one sample presented bands of between 300 and 350 base pairs. In GenBank, this sample matched 100% with Leishmania infantum (314 base pairs). The results suggest that cattle can be infected by Leishmania infantum in Brazil.


Resumo Leishmania spp. são agentes causadores das leishmanioses em humanos e em animais, gerando grande impacto à saúde pública. Este estudo objetivou detectar a circulação de Leishmania spp. em área não endêmica para leishmaniose visceral de São Paulo, Brasil. Foram extraídas amostras de DNA de 100 novilhas da cidade de Pirassununga. Estas amostras foram amplificadas com os iniciadores específicos para tripanosomatídeos Internal Transcriber Spacer 1 (ITS1). Os ensaios revelaram uma amostra com bandas entre 300 e 350 pares de base (pb). A amostra demonstrou 100% de identidade com Leishmania infantum (314 pb). Os resultados sugerem que o gado pode ser infectado por L. infantum no Brasil.
