Toxoplasma gondii antibodies on domiciled cats from Lages municipality, Santa Catarina State, Brazil.

Sera were collected from 300 domiciled cats from the municipality of Lages, Southern Brazil, to determine the prevalence of Toxoplasma gondii antibodies and risk factors associated. Tests for T. gondii antibodies were performed using indirect immunofluorescent antibody test (IFAT). Positive reactions with titers ≥1:64 were found in 43 (14.33%) cats. A significant number of seropositive cats were ≥6 month old (p = 0.03758) and had access to the streets or/and rural areas (p = 0.04185). The results indicate that T. gondii is widespread in cats in Lages with a prevalence of 14.33%.
