Cryptosporidiosis distribution and clinical manifestation in cats in Tyumen

The aim of research is to study the spread of cryptosporidiosis among Tyumen cats, as well as the clinical manifestation of this invasion in these animals. The studies were carried out in the period from 2018 to 2020 on the basis of veterinary clinics in Tyumen, where 134 cats with signs of enteritis were examined. Based on the study of feces by the native smear method and immunochromatographic testing, a total of 23 cats affected by cryptosporidium were identified, which amounted to 17.2 % of the total number of animals tested. Digital data on the age structure of the disease revealed that cryptosporidiosis in animals aged 1 to 5 years was observed in 60.9 % of cats, at the age of 6-9 years - in 26.1 % of individuals and at the age of 10-13 years - in 13.0 % individuals. Among outbred animals, the invasion of protozoa (43.5 %) was higher than in purebred cats (4.3-26.1 %). The pathological effect of cryptosporidium on the organism of invasive cats was accompanied by changes in the cellular composition of the blood: a decrease in erythrocytes, platelets and hemoglobin, leukocytosis and an increase in ESR (significant at P
