  Este trabalho descreve a detecção de aglutininas anti-Leptospira spp. em tracajás (Podocnemis unifilis) na região Amazônica.

  Obtivemos 98 amostras de soro, as quais foram submetidas ao teste de aglutinação microscópica (MAT), utilizando 31 antígenos de diferentes sorogrupos de Leptospira spp. Das 98 amostras de soro coletadas, 35% (34/98) reagiram apresentando titulações de 100 a 3200; 23,53% dessas amostras (8/34) coaglutinaram na presença de dois ou mais sorovares. O sorogrupo mais comum foi Hebdomadis com 26,9% (7/26), seguido de Semaranga com 23% (6/26), Shermani com 19,2% (5/26), Djasiman com 11,5% (3/26), e Australis com 7,7% (2/26). Bataviae, Javanica, e Sejroe foram representados com apenas uma amostra (3,9%). A presença de tracajás reagentes a anticorpos contra Leptospira spp. implica na exposição ao patógeno.

  We describe anti-Leptospira spp. agglutinin in yellow-spotted river turtles (Podocnemis unifilis)in the Amazon region. Ninetyeight serum samples from individuals housed at the Bosque Rodrigues Alves Zoobotanical Garden of Amazonia, Belém, PA, Brazil, were subject to the microscopic agglutination test (MAT) using 19 different Leptospira spp. antigen serogroups. Thirty-four of the 98 samples (35%) were reactive, with titers ranging from 100 to 3200, and eight 8 reactive samples (23.5%) co-agglutinated under two or more serovars.The most common serogroup was Hebdomadis (26.9%, 7/26), followed by Semaranga (23%, 6/26), Shermani (19.2%, 5/26), Djasiman (11.5%, 3/26), and Australis (7.7%, 2/26); Bataviae, Javanica, and Sejroewere represented by a single sample each (3.9%). The presence of turtles reactive to anti-Leptospira spp. antibodies implies exposure to the pathogen
