Frequência de anticorpos contra Leptospira spp. e Trypanosoma cruzy em primatas neotropicais mantidos em cativeiro

Abstract

Make a serological survey for antibodies against Leptospira spp and Trypanosome cruzi in Neotropical primates kept in captivity. 94 samples of neotropical primates adults, males and females of different species kept in captivity in the Primates National Center - Ananindeua- PA, collected for the accomplishment of the Microscopic Agglutination Test (MAT), in the which was used 84 serum samples, of which 35 (41.67%) presented antibodies against leptospira and 49 (58.33%) were seronegative. From 11 species used in research, the highest positivity was in the species of Cebus apella (69.23%), Aotus infullatus (33.33%), Callithrix penicillata (28.57%) and Saimiri sciureus (22.73%). From 35 positive samples, 11 (31.42%) reacted against serovar Cynopteri, eight (22.85%) were reagents for Andaman, six (17.14%) against serovar Hebdomadis, four (11.42%) for Copenhagen, three (8.57%) against serovar Patoc, two (5.71%) to serovar Cuíca, and the remainder responded to at least one serovar (2.85%) serovar Hardjo, Icterohaemorrhagiae, Javanica, Grippotyphosa and Autumnalis. To detect the anticorpos against T. cruzi, were used 94 samples of neotropical primates. The samples of each animal were submitted to the Indirect Hemagglutination (IHA) and Enzyme- Linked Immunosorbent Assay (ELISA). Of samples avaluated by IHA, only one female from the specie Saguinus niger showed result positive, but, all samples showed result negative when avaluated by ELISA. In relation to hematological and biochemical parametes, were not observed alterations that indicated a possible infection. It is concluded that the occurrence of antibodies against leptospires in species of primates was relatively high, even showing symptoms, and all hematological and biochemical parameters were normal indicating that although these animals find themselves in captivity, possibly had contact in the wild life with the bacterium, and the infection may be maintained between them and cases of leptospirosis e Chaga’s disease in neotropical primates are rares, but we should remember that they act with reservoir of Leptospira spp and Tripanosma cruzi at wild environment.
