Keywords:Toxoplasmosis, Cat, Serology
AbstractSerum samples of 191 cats from 3 cities of São Paulo State and 1 of Paraná State were tested by indirect immunofluorescent assay (IFAT) for anti-toxoplasma IgG antibodies. Of the total, 56 (29.3%) were pure breed cats and 135 (70.7%) were mongrel cats, 88 (46.1%) and 103 (53.9%) were females and males, respectively, with ages ranging from two months to eighteen years. 37 (19.4%) samples reacted positively to IFAT, with 1/16 (n=10; 27.0%), 1/64 (n=18; 48.6%) and 1/256 (n=9; 24.3%) titres. No significant correlation was observed between sex, breed, origin or age (p >; 0.05), however the infection rate was higher in old animals, with 13.2% in animals between two months and three years old, 23.5% between three and six years old, 17.6% between six and nine years old, 25% between nine and 12 years old, 20% between 12 and 15 years old and 50% between 15 and 18 years old.
