SEROPREVALENCE OF TOXOPLASMA GONDII IN DOGS AND CATS DOMICILED IN THE WEST OF SANTA CATARINA, BRAZIL

Abstract

Toxoplasma gondii is a protozoan with worldwide distribution, responsible for causing toxoplasmosis, a disease that affects mammals, reptiles, amphibians and birds. The objective of this study was to evaluate T. gondii seroprevalence in dogs and cats domiciled in cities from West and Serrana mesoregions of Santa Catarina. A total of 338 blood samples, 211 from dogs and 127 from cats were collected and submitted to the indirect haemagglutination technique (IHT) for the detection of anti-T. gondii antibodies. Epidemiological questionnaire asking for information related to gender, breed, temperament, behavior, immunity, body index, diet, ectoparasites, access to the streets, hunting habit was applied to the animals owners. The results were 71.89% (243/338) of seropositive animals, being 69.19% (146/211) dogs and 76.38% (97/127) cats. The variable that presented statistical significance was commercial ration for dogs as protection factor. The present study demonstrates a high prevalence of anti-T. gondii antibodies in dogs and cats domiciled in West and Serrana mesoregions of Santa Catarina state, Brazil. Through the obtained results we can reinforce the importance of feeding dogs with commercial food, rather than home-made food, avoiding the consumption of raw or undercooked meat by the animals.
