SARCOCYSTIS IN SOME RODENTS AND BIRDS

Abstract

Sarkosporidiosis is a chronic animal disease that often results in death. In animals with severe damage to the body by sarkosporidiosis, weakness, tissue depletion and hydremia are observed. Sarcocyst development occurs in muscle cells and tissues. It is known that in vivo predators become infected by eating meat from animals affected by sarcocysts. Sarcocysts secrete toxic substances, sarcocystin and sarcosporiocin, which lead to the death of animals within 5-20 hours. In chronic conditions in animals, salt deposits form around numerous sarcocysts and pronounced skeletal muscle hydremia is also observed. Sarcocystosis can be detected only after the death of animals. The corpses of animals must be examined microscopically, severely damaged corpses should be buried to a depth of 2 meters. When conducting microscopic studies of slices taken from samples of affected animal meat, a diagnosis is established. The proposed work is devoted to study the fauna and cycles of the development of micromorphology of representatives of the genus Sarcocystis of some rodents and birds. To achieve this research, an experiment was conducted with small vertebrates. The goal of our work is to identify the distribution of sarcosporidia of some species of rodents and birds, to study the morphology of the detected sarcosporidia, and their life cycle. The results of the study can be used for the epizootological characterization of sarcocystosis of rodents and birds. The study of the life cycle and specific structure is necessary for the diagnosis of species of the genus Sarcocystis. Yellow ground squirrel, house mouse and chukar can serve as a laboratory example in the study of mammalian and bird sarcocystosis. Ultrastructure materials and the life cycle of sarcosporidia can be used in studying the courses “Parasitology” and “Invertebrate Zoology”. There are 5 articles that were published on materials of this work.
