Serological prevalence of Toxoplasma gondii infection in cats (Belém, Pará, Brazil)

Abstract: Abstract We evaluated the prevalence of anti-Toxoplasma gondii antibodies in the serum samples collected from domestic cats in Belém, Pará, Brazil. We also correlated the presence of T. gondii antibodies with environmental variables and cat-owner habits. Four-hundred and forty-seven serum samples from domestic cats were analyzed. The sera were tested using an indirect immunofluorescence assay. Among the animals analyzed, 21.92% (98/447) were seropositive. A statistically significant association was fou… Show more

“…The seropositivity observed in feral cats herein was significantly higher than the 16.3% (46/282) observed in owned cats in the same city [38] but lower than the 84.4% (49/58) found in other Paraná state areas. In addition, 21.92% (98/447) of domestic cats were seropositive in northern Brazil, with a statistically significant association between age and serology among cats over 1 year old [39]. Contact with cats or with soil containing infective T. gondii oocysts has already been established as a risk factor for toxoplasmosis [14].…”

“…This questionnaire included epidemiological variables related to general information about the animal's lifestyle and management. To identify possible risk factors for T. gondii infection in these animals, the following variables were selected: sex [52,86], age [5,65], breed [6,56], street access [9,67], contact with cats [12,66], presence of rodents [48], type of food (dry and wet commercial food, meat and embedded, homemade food, offal and other types of food, like fruits and vegetables) [14,79] and water source for animals' consumption [8].…”

“…In humans, besides ingestion of cysts, transmission can also occur through sporulated oocysts from feces of infected cats in the environment and transplacentally (tachyzoites) [7,23]. Risk factors associated with feline infection are sex, age, eating habits, coexistence with other species, and consumption of raw and undercooked meat and contaminated water [25].…”
