Pathoanatomic Changes in Helminthic Diseases of Karakul Sheep

Many helminthiasis of sheep, in particular gastrointestinal, they cause significant economic damage to sheep breeding. An analysis of the literature and the results of many years of research by Uzbek scientists shows that with pasture keeping of sheep, almost all animals in the flock are infected with different types of helminths, mainly strongyloids. It should be noted that helminthic diseases, as a pathological condition of the body, does not stop with the elimination of the pathogen. Restoration of impaired body functions occurs over a more or less long time and this is due to the intensity of invasion, as well as the type of pathogen and immunoreactivity of Karakul sheep. And our research allows us to find out pathological changes in the body during pasture and experimental infection of an animal. The purpose of the work. Subject to a thorough pathoanatomic examination of experimental and pasture animals. Materials and methods of research. For experiments on the study of experimental marshallagiosis and nematodirosis of sheep, 13 agelmentose Karakul sheep and 14 fallen animals were taken. Results. Among the pathological changes that are important for pathoanatomic diagnostics, as well as for clarifying pathogenesis issues, changes in the rennet and small intestine of the invaded animals play a special role. The dynamics of pathological changes in the rennet and small intestine (hyperemia, hemorrhages, erosion, development of parasitic nodules, ulceration) during the growth and development of marshallagias indicate the mechanism of their pathogenic action at different stages of their development and the response of the immunobiological reaction of the animal organism. The survival rate of marshallagia in sheep has been established in the range from 5.46% to 29.56%, and nematodes - from 1.18% to 9.58%. Analysis of the results of pathoanatomic studies has shown that with experimental marshallagiosis and nematodirosis, lambs develop deep pathological processes. Conclusions. The degree of pathological changes that occur in the body when strongylate is parasitized primarily depends on its individual sensitivity and resistance. Weakly resistant animals react strongly to the parasitization of even a small number of helminths. The number of helminths and the age of the animal also play an important role in the development of the pathological process.
