Abstract
Cats play crucial roles in the epidemiology of toxoplasmosis. In the present study, a total of 198
companion cats of different ages were examined for serum antibodies against Toxoplasma gondii by
immunochromatography assay and for oocyst presence in faeces by microscopic examination (flotation
method) and immunochromatography assay. The cats were selected between referred cases to the Veterinary Hospital of Ahvaz University, southwestern Iran from December 2006 to November 2009. Classification was made by age, sex, breed, region and season. The studied cats were divided into three groups based on age (<6 months, 6 months–3 years and >3 years) and into five regions based on area (north, east, west, south and
central). The results were analyzed by Chi-square analysis, Fischer’s exact test and Z test. Forty nine of 198
serum samples (24.75%) had antibodies against Toxoplasma gondii (95% CI: 18.7-30.7%). Prevalence was
significantly higher in adult cats above 3 years (38.8%) and 6 months–3 years (26.6%) compared with cats
less than 6 months (3.8%) (P<0.001). Prevalence was higher in male cats (29.7%) than females (20.6%), in the summer season (26.2%) and west region (27.5), but the difference was not significant between the
prevalence of infection relative to host gender (P=0.14), season (P=0.99) and region (P=0.98). Faecal
flotation technique and immunochromatography assay was carried out on faecal samples also and T. gondii
oocysts were not detected in any of the 198 samples. Our study showed that the prevalence of infection
(24.75%) is relatively high in serum of companion cats in the Ahvaz district.
