Negative results for anti-Leptospira sp. agglutinins in free-living Iguanas (Iguana iguana) from the Amazon region of Brazil

Abstract

Although, serological studies for leptospirosis in iguanas have already been performed, there is no report in the Amazon region. Therefore, the present study aimed to investigate the presence of anti-Leptospira sp. in free living Iguanas-verdes (Iguana iguana) of Mangal das Garças Park, metropolitan region of Belém, Pará, Northern region of Brazil. Twenty-nine blood samples of Iguana-verde (I. iguana) were collected from Mangal das Garças Park. For the serological diagnosis of Leptospira sp. it was employed microscopic agglutination test (MAT) with 25 live antigens of Leptospira sp. as antigens. It was observed that all samples were non-reactive, suggesting no exposure to the agent.
