Pathomorphological changes of the stomach and intestinum crassum in the intestinal form of parvoviral enteritis in dogs

Based on the analysis of literature sources, monitoring results and our own research, it has been established that viral enteritis occupies a leading place in infectious pathology dogs causes significant damage to animal owners. Viral enteritis, most commonly caused by parvovirus, severe gastrointestinal disorders is one common diarrhea under 6 months age. Therefore, given relevance this issue, result study clarify, supplement summarize data pathomorphological features intestinal form parvovirus infection dogs. Diagnostic studies confirm were performed using VetExpert CPV Ag or CPV/CCV rapid tests, as well ELISA PCR. Dissection dead animals was conventional sequence. For examination, samples taken from tract, fixed 10 % neutral formalin solution, followed dehydration alcohols increasing concentration procedure organ compaction according generally accepted method. Histological sections 6–10 μm thick obtained microtome. The article presents pathological changes with namely macroscopically serous membrane stomach revealed striped hemorrhages, duodeno-gastric reflux, manifested gray-green color mucous (bile accumulation). methods have shown blood vessels submucosal base are clearly dilated, filled blood. swollen, unevenly colored all parts stomach. In muscular wall, vast majority cells state granular dystrophy, some animals, necrotic smooth muscle tissue recorded. Histochemical development microscopic indicated hypersecretion mucus (acidic proteins) sick No specific macroscopic colon Microscopically, small amount cellular detritus fragments, goblet cell hyperplasia, reaction epithelial granular, less often, hydropic dystrophy recorded lumen mucosal surface.
