SOME EPIDEMIOLOGICAL CHARACTERISTICS, CLINICAL SYMPTOMS AND HEMATOLOGY OF DOGS INFECTED WITH CANINE PARVOVIRUS TYPE 2 (CPV-2) IN BUON MA THUOT, DAK LAK

Abstract

Canine parvovirus type 2 (CPV-2) is a cause of gastroenteritis in dogs with a high mortality rate. This cross-sectional study aimed to determine the epidemiological, clinical, and hematological characteristics of dogs infected with CPV-2 in Buon Ma Thuot city, Dak Lak province. By testing vomit or stool samples collected from 597 dogs using the Ag-ELISA kit test, the result showed that the percentage of dogs infected with CPV-2 was 10.05% (95% CI: 7.81–12.81%). Multivariable logistic regression analysis showed that dogs >6 months old and vaccinated dogs had a 72% and 74% lower risk of being infected with CPV-2, respectively, when compared with dogs ≤6 months old and unvaccinated dogs. Dogs with CPV-2 had the main symptoms of anorexia, fatigue, vomiting, and diarrhea with a fishy smell and blood, accounting for 91.67–100% of dogs monitored. Blood tests showed that the infected dogs had a decrease in granulocyte count (GRAN), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin concentration (MCHC).
