Abstract

Toxoplasma gondii is an obligate intracellular apicomplexan parasite that causes abortion and reproductive disorder in domestic animals. T. gondii is a common worldwide disease in homeothermic animals, including birds and humans. The aim of the present study was to determine the presence of antibodies against T. gondii in the armadillo Chaetophractus villosus in the province of La Pampa, Argentina. Serum samples were collected from 150 individuals (70 males and 80 females). For serological detection of T. gondii, a latex agglutination test was first performed and then positive sera were confirmed with an indirect hemagglutination test, using 1:4 to 1:64 dilutions. Results showed that 27% (41) of the samples presented titers for antibodies against T. gondii. There were not significant differences between the presence of antibodies against T. gondii and age or sexes of the armadillos. Results show that presence of T. gondii antibodies in armadillos were associated with presence of pigs, and sheep, however there was not association with chickens and dairy cattle in capture site. T. gondii has an important presence in C. villosus population, suggesting a potential zoonotic risk for humans and wildlife animals when C. villosus meats are consumed raw or undercooked. This is the first record of the presence of antibodies against T. gondii in C. villosus.
