Патоморфологічна характеристика парвовірусного ентериту в собак

Abstract

Viral enteritis occupy a leading place in the infectious pathology of dogs and lead to severe disorders of such systems as the gastrointestinal, cardiovascular and respiratory.The comprehensive diagnosis of this pathology in dogs is not developed enough. The high variability of clinical signs for parvovirus enteritis, the complexity of the appeal with a large number of qualitative indicators, complicate the diagnosis of this disease for a practical veterinarian. The methods of pathomorphological diagnosis are simple, cheap and accessible to any veterinarian doctor. It is precisely from them that the causes of death of the animal begin to be established, with many diseases and pathological conditions, these methods remain decisive when making a diagnosis.The aim of the work was to study and analyze the pathomorphological features in parvovirus enteritis of dogs.Materials and methods of research. The work was carried out at the Faculty of Veterinary Medicine of the Zhytomyr National Agroecological University, as well as in the veterinary clinics of the city of Zhytomyr: the private veterinary clinics «Bagira» and «Doctor-Zoo», the educational and scientific-production clinic of veterinary medicine of the Faculty of Veterinary Medicine of the (ZNAEU) in the city state Zhitomir Hospital of Veterinary Medicine and Aybolit Private Veterinary Clinic in the period from 2014 to 2017 in breeding and breeding dogs.Diagnostic studies to confirm parvovirus enteritis were performed using the VetExpert and ELISA and PCR rapid tests on the basis of the private veterinary laboratory of Bald Ltd. (Kyiv).The pathoanatomical section of dogs of all ages who died from parvovirus enteritis was performed by partial evisceration in a generally accepted sequence.The article presents the results of the study of pathoanatomical changes in dogs for parvovirus enteritis, which depended on the form of manifestation of the disease – intestinal, cardiac or mixed. The most pronounced pathological and anatomical changes were found in the gastrointestinal tract (intestinal form), mainly in the small intestine.In the dead animals, a complex of pathoanatomical signs that can be considered characteristic of parvovirus enteritis are found: hemorrhagic enteritis, serous-hemorrhagic inflammation of the mesenteric lymph nodes, signs of hepatitis, acute altered myocarditis, and in the lungs – hemorrhages and foci of atelectasis and enlargement of the spleen.
