Prevalence of cryptosporidian infection in cats in Turin and analysis of risk factors.
An epidemiological study was carried out to identify factors associated with the risk of cryptosporidian infection in cats. Faecal samples from 200 domestic cats were collected in the small animal clinic at the Faculty of Veterinary Medicine in Turin (north-west Italy). The faecal samples were analysed for the presence of Cryptosporidium species oocysts using a centrifugation concentration floatation method. For each cat, age, sex, breed, indoor/outdoor status, diet, diarrhoea and presence of other enteric parasites were analysed for association with Cryptosporidium species infection. Cryptosporidia oocysts were identified in 49 cats (24.5%) aged from 2 months to 18 years. Statistical analysis revealed that four variables are significantly associated with an increased risk of infection: less than 1 year of age (chi(2)=6.5, P=0.01), feeding home-cooked diet (chi(2)=6.92, P<0.01), presence of diarrhoea (chi(2)=4.34, P<0.037), and presence of other enteric parasites (chi(2)=10.31, P<0.01). No statistical differences were found for sex (chi(2)=1.56, P=0.21), breed (chi(2)=0.78, P=0.38) and outdoor/indoor status (chi(2)=1.49, P=0.22). Cryptosporidium species was the parasite most frequently detected in the cats surveyed.
