The case of acute clostridial infection in Asian black bear in captive

The aim of the work was to find out the death of a female Himalayan bear, since the number of individuals of this species in nature is declining. The material for the study was the corpse of a female Himalayan bear, which suddenly died in the Perm Zoo on October 27, 2021 at the age of 32 years. Pathological anatomical autopsy methods were used according to GOST R 57547-2017, histological with hematoxylin-eosin and Gram-stained sections, as well as microbiological (MU 4.2.2723-10 and GOST 26503-85). As a result, the pathoanatomical diagnosis was: splenitis, myocardial ischemia, catarrhal-hemorrhagic enteritis, myocardial hypertrophy, gas embolism of the liver vessels, endometritis. Conclusion - the death of the animal occurred as a result of acute heart failure due to intoxication, probably caused by anaerobic microflora. Clostridium septicum (Mace 1889) Ford 1927 was isolated from tissues. Histological conclusion: the animal died as a result of septic shock caused by Clostridium infection and progressive heart failure. To prevent subsequent deaths of animals, it is necessary to carry out a set of preventive measures to disinfect the premises, the site for dissection, cleaning equipment, feeders and drinkers. Carry out decontamination. Pay attention to the quality of hay used for animals. The well-being of zoo animals requires the organization of work to combat infectious diseases common to domestic and wild animals in accordance with a single health strategy.
