Negative serosurvey of Toxoplasma gondii antibodies in Golden-headed Lion Tamarin (Leontopithecus chrysomelas) from Niterói/RJ, Brazil

Pesquisa sorológica de anticorpos anti-Toxoplasma gondii em Mico-leão-da-cara-dourada (Leontopithecus chrysomelas) de Niterói/RJ, Brasil

Abstract

New World Nonhuman Primates are highly susceptible to clinical toxoplasmosis. Serum samples from 126 recently captured Leontopithecus chrysomelas, from an exotic and invasive population, were tested for Toxoplasma gondii antibodies by the modified agglutination test (MAT, cut-off 1:25); all were seronegative. The MAT is highly specific and is not species-specific. This is the first report of T. gondii survey in this tamarin in the wild. This result is consistent with prior reports that showed the high susceptibility of the species to infection by T. gondii usually with high mortality rates.
