EPIZOOTIC SITUATION ON THE CONTAMINATION OF ENVIRONMENTAL OBJECTS WITH INVASIVE ELEMENTS ON THE CATTLE FARM OF THE MOSCOW REGION

The study of the epizootic situation on the contamination of environmental objects with invasive elements on the livestock farm of the Moscow Region showed its contamination with parasitic protozoa oocysts and cysts, and helminth eggs and larvae which was directly affected by infection of the livestock with the above parasites and the quality of therapeutic and prophylactic and veterinary and sanitary measures. The objects of the external environment most contaminated with invasive elements of parasitic protozoa and helminths were the floor of stalls and passages in the premises for keeping animals. The stall walls and animal feeders were less contaminated with parasitic protozoa oocysts and cysts or helminth eggs or larvae. It should be noted that, the epizootic process for parasitic protozoa: Buxtonella, Cryptosporidium, Eimeria and Strongylata of the digestive tract, was permanent on the examined livestock farm of the Moscow Region, since all of its components were in place: the source of invasion was infected animals; transmission factors were environmental objects contaminated with invasive elements and susceptible animals, especially young animals. An analysis was performed of the plan of preventive antiepizootic measures of this farm in relation to parasitic diseases in terms of diagnostic tests for parasitosis, and therapeutic-and-prophylactic and veterinary-sanitary treatments.
