Lemur Loris Digestive Tract Pathologies (Dissection Study)

Abstract

A necropsy study of the Lemur Lori was carried out. Physiologically, Lemurs have a very sensitive gastrointestinal tract. Therefore, these animals almost keep the lead in the incidence of pathologies of the oral cavity, stomach, and intestines. The study was carried out in the dissection room of the Veterinary Medicine Faculty of the Altai State Agrarian University. The object was the animal corpse of a Lemur Loris: animal species: monkey; gender: female; age: 1.5 years; breed: Loris; the owner is a private zoo; provisional diagnosis: not known. The following methods were used: history taking; postmortem examination according to Shor’s method with a description of the results obtained; photographing; analysis of the data obtained with the help of fact-finding. As a result of the postmortem examination, the following changes were recorded: pulmonary edema, acute congestive hyperemia and emphysema; acute expansion of the right atrium and ventricle of the heart; acute catarrhal-hemorrhagic esophagitis and gastroenteritis; acute hemorrhagic pancreatitis; acute serous-hemorrhagic lymphadenitis of the mesenteric lymph nodes; liver and kidneys fatty degeneration; cyanosis of the conjunctiva, tunica mucosa of the mouth; obesity. Thus, death occurred as a result of pulmonary arrest (pulmonary edema), which was the result of autointoxication (inflammatory processes in the stomach, intestines, pancreas). The cause of autointoxication is a long-term and major violation of the norms of feeding and maintenance, stress, and presumably a drug that was administered to the animal, namely, an incorrect dose or individual intolerance of its constituent components.
