Abstract. The most susceptible to parvovirus infection are dogs aged 3-6 months, which is explained by the specific characteristics of this particular virus. The morbidity of The great interest in parvoviruses worldwide is due to several reasons. Under natural conditions, parvoviruses are pathogenic to mammals, birds, and humans. The diseases caused by these viruses cause significant economic damage to the livestock of many countries.
Depending on the severity of these clinical and morphological changes, there are three forms of manifestation of the disease: cardiac (myocardial), intestinal(enteral) and mixed (combined).
dogs with parvovirus infection is affected by seasonality. In the cold season (autumn and winter), both morbidity and mortality in animals increase.
Parvovirus enteritis is affected by dogs of all breeds, regardless of sex. Most often parvovirus enteritis was recorded in German shepherds, Rottweilers, spaniels, Caucasian and Central Asian sheepdogs.
The article presents the results of the study of pathoanatomical changes in dogs with parvovirus enteritis, with intestinal disease.
Diagnostic studies to confirm parvovirus enteritis were performed on dogs using rapid tests and PCR.
1. In the intestinal form of parvovirus enteritis, characteristic changes were observed in the small intestine. The mucous membrane of this section of the intestine is red or dark cherry in color, swollen, thickened, covered with mucus of the same color, with small speckled spots. The wall of the small intestine is thickened, the lumen of the intestine is narrowed. At the histological level, muscle hypertrophy, necrosis, dystrophic changes and destruction of crypt epithelium, eosinophilic bodies-inclusions in nuclei of epithelial cells of crypts were noted.
In mesenteric lymph nodes, signs of serous - hemorrhagic inflammation and lymphoid hyperplasia were recorded.
In the liver destruction of the beam structure, atrophy of the parenchymal elements, granular dystrophy of hepatocytes. In the spleen hemorrhagic heart attacks.
