Soroprevalência para anticorpos anti-Toxoplasma gondii em uma propriedade na ilha do Marajó, Pará, Brasil

Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, a mandatory intracellular parasite that has as its intermediate hosts several animal species, among them, equines. This work aimed to investigate the presence of anti-T. gondii antibodies in the serum of horses of the Marajoara and Puruca breeds from a property on the island of Marajo. The samples were submitted to the Modified Agglutination (MAT), in which the sera were diluted in the proportion of 1:25 to 1:800. Of the 45 horses evaluated, 13.3% (06/45) were serum reagents with titers ranging from 25 to 200. Regarding the epidemiological survey, it was observed that there was no statistical difference between the variables (race, sex, age, feeding and cohabitation with other animal species). It is concluded that in the environment there is the presence of the pathogen and causing infection, therefore it is suggested that there be more studies to elucidate the epidemiology of the parasite in the region.
