Macroscopic Changes in Dogs for Coronavirus Enteritis

Based on our analysis of literary sources, the results of monitoring and our own research, it was found that viral enteritis occupies a leading place in the infectious pathology of dogs and causes significant damage to animal owners. Given the relevance of this issue, the result of our research is the clarification, addition and generalization of data on the patho-morphology of various organs of dogs with coronavirus enteritis, which will make it possible to find out in more detail the effect of the causative agent of the disease on the animal body. The article presents the results of the study of macroscopic changes in dogs with coronavirus enteritis. According to the results of the pathological and anatomical autopsy of the puppies, microscopic changes are observed in the internal organs, namely, serous lymphadenitis, swelling and hyperemia of the thymus and pancreas, the kidneys are unevenly colored brown with local infarctions in the heart, enlargement of the left part, spotty hemorrhages in the spleen, lungs in places had signs of hemostasis, the mucous membrane of loops of the small intestine with signs of catarrhal and hemorrhagic inflammation. Lymph nodes, moderately hyperplastic, with signs of hemorrhagic inflammation. The set of patho-anatomical signs listed above can be considered characteristic of canine coronavirus enteritis. Thus, the set of patho-anatomical changes we discovered in puppies with coronavirus infection can be considered a characteristic criterion for the patho-morphological diagnosis of coronavirus enteritis in dogs.
