SEASONAL DYNAMICS OF CRYPTOSPORIDIOSIS INFECTION FROM CALVES

Abstract

The analysis of degree of contamination of cattle of a protozooses on farms of the Udmurt Republic revealed a tendency to increase an invasion of animals the Cryptosporidium parvum pathogen. The presence of pathogen associations makes it difficult to detect a specific representative of the variety of parasitic diseases. The material functioned as samples of feces from calves, which investigated the generally accepted scatological flotation methods and by staining smears of feces with carbolic fuchsins according to Zil-Nielsen and then studying the preparations using an immersion microscope system.We have found that cryptosporidiosis in calves aged from 3 to 90 days is recorded throughout the year, indicating a constant circulation of the pathogen among susceptible animals within the livestock premises. Results of researches showed that the winter-spring period is the most favorable for the development of Criptosporidium parvum in livestock complexes Udmurt Republic. The peak of invasion (77.78%) in March is primarily due to mass calving, a decrease in the natural resistance of animals, as well as climatic features of our region. The obtained results must be considered in the development and implementation of therapeutic and preventive measures to combat cryptosporidiosis of calves.
