Toxoplasma gondii in domiciled dogs and cats in urban areas of Brazil: risk factors and spatial distribution

Abstract: Toxoplasma gondii is a highly prevalent zoonotic parasite in Brazil capable of infecting mammals and birds. The increase in the urban populations of pets and the narrowing of the human–animal relationship can facilitate the transmission of important public health zoonoses, such as toxoplasmosis. This study aimed to evaluate the frequency and spatial distribution of T. gondii infection and its risk factors in domiciled dogs and cats attended at the Jorge Vaitsman Institute, Rio de Janeiro. Serum samples from 40… Show more

“…Dogs have also been proposed as toxoplasmosis sentinels for human infection, mostly due to sharing inhouse spaces and related exposure to food and water sources [ 6 , 7 , 8 ]. The overall seropositivity in dogs in this study (23.3%) was lower than the 40.8% in Bahia State, northeastern Brazil [ 48 ], 40.0% [ 10 ] and the 25.4% in Sao Paulo State, southeastern Brazil [ 8 ], the 36.5% in Bahia State, northeastern Brazil [ 49 ], the 34% in Rio de Janeiro State, southeastern Brazil [ 50 ], and the 32.7% in southern and central-western Brazil [ 28 ]; only higher than the 16.3% [ 27 ] and the 7.95% in the same Parana State, southern Brazil [ 9 ]. In addition, the observed seropositivity herein was lower than the 72.7% in Cuba [ 7 ] and higher than the 18.6% [ 51 ] and the 21.6% in China [ 52 ].…”

“…Serum samples were analyzed for antibodies to T. gondii by the indirect fluorescent antibody test (IFAT) as described by Camargo (1964) . The test was positive when the tachyzoite surface was totally fluorescent and the titer was at least 1:64 ( Arruda et al, 2021a ). Fecal samples were obtained by washing the rectal ampoule with sterile saline ( Pereira et al, 2017 ).…”
