Monitoring of parasitic diseases in productive animals in the Samara region
Abstract
The purpose of the research: to monitor the epizootic situation on parasitic diseases in productive animals in the Samara region using a database. materials and methods. Research was performed at the Department of invasive diseases of Samara Research Veterinary Station Samara RVS FSBSI. Fecal samples from productive animals were examined by Fuelleborn’s method using polymerase chain reaction to visualize species-specific DNA sequences, and an immune chromatographic method in detecting of antigens Dirofilaria immitis in serum, plasma and whole blood of dogs and oocysts Giardia duodenalis in dogs’ feces. The extensity of invasion was estimated with regard to the number of analyses of biomaterial from animals whose owners consulted veterinary physicians. For the monitoring, we used the database “Parasitic diseases in productive animals and small domestic animals in the Samara region” developed in Samara RVS in 2013 which enables to monitor the health status of the animal during its lifetime as well as epizootic situation on parasitic diseases in single localities, economies, districts and in Samara region in general. Results and discussion. Research results revealed that Strongylata had been registered in 17 districts at extensity of invasion from 5 to 70%, Strongyloides, Moniezia, Trichocephala - in 10 districts (EI 10-80%), Skrjabinema - in 7 districts ( EI 5-10%), Nematodirus - in 5 districts (EI 20-80%), Parascaris, Ascaris, Paramphistomum - in 3 districts (EI 5-40%), Fasciola, Coccidia, Dictyocaulus - in 2 districts (EI 5-15%). The biggest species diversity of helminths (7 species) were found in Bolsheglushitsky, Kinelsky and Borsky districts of the Samara region. The monitoring showed the decrease in worm species diversity in 2016 in all districts of Samara region compared to 2015. Parasitic protozoans, Eimeria, were found in all districts of the Samara region. A significant reduction of worm species diversity was associated with permanent planned treatment of productive animals with anthelmintics. The results obtained were used in a number of livestock farms of the Samara region to control the epizootic situation as well as for treatment and prevention of diseases in productive animals.
