Abstract

Cats are important in the epidemiology of Toxoplasma gondii because they are the only hosts that can excrete environmentally resistant oocysts. T.gondii is a major zoonotic agent which infects up to one-third of the world population. Toxoplasmosis in neonates and immunocompromised patients can lead to severe disease and death. A cross- sectional parasitological and serological survey with latex agglutination test (LAT) to detect anti-T. gondii antibodies was conducted on 100 serum samples collected from stray cats in five urban areas of Sari, Northern Iran, from April to November 2004. Classification by age, sex, weight, season and region was made. Results analyzed according to specific variables. The overall prevalence of T. gondii IgG antibodies (LAT titre ≥1:1) were found in 40 of 100(40%) of stray cats, with regional variations. Overall 16 of 100(16%) of stray cats had diagnostically significant antibody titres (LAT ≥ 1:64). Prevalence was significantly higher in adult cats (1.5–3.0 kg, 54.5% of 66) than in juvenile cats and kittens (≤1.4 kg, 11.8% of 34) and higher in female stray cats (44.4% of 72) than in male stray cats (28.6% of 28). Toxoplasma seroprevalence was highest in the season of spring (22.4%). There was a significant difference in the prevalence of infection relative to host age and weight (P < 0.05). No significant difference was found between the prevalence of infection relative to host gender, urban sites and season (P > 0.05). Prevalence of T. gondii oocyst was also analyzed by a routine coprological method in 100 cats. T. gondii oocysts were not found in any faecal samples analyzed. Only 2 out of 100 smear preparations of intestinal mucosa showed trophozoites of T. gondii.
