TO THE QUESTION OF PATHOMORPHOLOGICAL CHANGES IN THE LIVER OF A SLOTH WITH PNEUMONIA
Sloths have their own characteristics of the structure and functioning of organs. They have a very low metabolic rate. Their food is digested for a month. Sloths use dew to drink. The intestines and bladder are emptied every 7-10 days, for which they descend to the ground. The liver is the main organ in which, along with target organs, pathological changes occur in various diseases. They affect the function of both the organ and the organism as a whole. Therefore, the study of this organ and the identification of changes is very valuable for veterinarians. The aim is to study pathomorphological changes in the sloth liver in case of pneumonia. The study was conducted at the Department of Anatomy and Physiology of the Northern Trans-Urals State Agrarian University. A sloth diagnosed with pneumonia was examined. At autopsy, a small amount of clear fluid was observed in the abdominal cavity. The sloth liver has its own structural features. The right and left lobes are fused and measure: 4.0 cm x 5.6 cm. The caudate lobe has a very large caudate process that extends beyond the ventral edge of the liver, its dimensions are 5.2 cm x 2.6 cm. The mastoid process is small, its dimensions are 2.1 cm x 1.6 cm. The liver had sharp edges, it was filled with blood on the cut. The weight of the sloth liver is 27.989 g, the relative weight of the liver to body weight is 1.33%. However, with pneumonia, pronounced histological changes in the liver are observed, which are characterized by atrophic and necrotic changes in the parenchyma of the organ, which in turn adversely affects its function.
