Abstract
Leishmania infantum and Trypanosoma cruzi are zoonotic parasites that are endemic throughout many parts of Latin America. Infected dogs play an important role in transmission of both parasites to humans. A serological survey of Leishmania and Trypanosoma infection was conducted on 365 dogs from São Paulo, Brazil and Bogatá, Colombia, South America. Serum samples were examined by the indirect immunofluorescent antibody test (IFAT). Anti-Leishmania IgG antibodies were detected in 5 of 107 from Brazil (4.7%) and in 4 of 258 dogs (1.6%) from Colombia. Titers ranged from 1:25 to 1:100. Anti-T. cruzi antibodies were not detected in any of the dogs from either Brazil or Colombia. The results show a low prevalence of anti-Leishmania antibodies and no antibodies against T. cruzi in these canine populations. Our study suggests that dogs play a limited role in the spread of L. infantum and T. cruzi in these urban areas of Brazil and Colombia.Entities:
