A Comparative Study on Prevalence of Canine Parvovirus Infection in Dog Between CVASU, Bangladesh and VCRI-MVC, India

Abstract

Canine parvovirus (CPV) infection is the most highly infectious and contagious viral disease in dogs. A comparative study on canine parvovirus infection among the hospitalized dogs at CVASU (Chittagong Veterinary and Animal Sciences University) in Bangladesh and VCRI-MVC (Veterinary College and Research Institute-Madras Veterinary College) in India was conducted between January 2017 and May 2017. A total of 50 hospitalized dogs at CVASU and 110 hospitalized dogs at VCRI-MVC of different breeds were clinically examined for the diagnosis of CPV Infection. Tentative diagnosis was performed on the basis of history of illness and clinical symptoms expressed by the dogs. The clinical signs was observed among the CPV infected dogs were blood with diarrhoea (91.42%), vomition (94.59%) and dehydration (severe 84.28%, moderate 20.0% and mild 8.0%). Age, sex, breeds of different dog and vaccination status were also considered for risk factors analysis. The overall prevalence of CPV infection was higher in VCRI-MVC (45.45%) than CVASU (42%).The prevalence of CPV was varied significant (P<0.05) among different age, vaccinated and non-vaccinated dog. Highest prevalence 52.94% was found in 1-3 months, 36.67% in 4-6 months and 33.33% in > 6 months old dogs respectively. Highest prevalence was observed in non-vaccinated (60%) compared to vaccinated (8.8%) dogs at CVASU, Bangladesh. In VCRI-MVC, India rate of infection also varied significantly (P<0.05) according to different age groups (81.82%, 38.18%, 9.09% among 1-3 months, 4-6 months and > 6 months respectively) and 14.29% in vaccinated and 64.71% in non-vaccinated groups. Significant (P<0.05) variation also observed in different breeds of dogs 61.9%, 60.0%, 37.14%, 29.17% and 40.0%, among Indigenous, GS, Rottweiler, Spitz and Doberman respectively. The current study was based on hospitalized patients, so a comprehensive study including all the dog population is required to precisely conclude about the prevalence and risk factors of CPV infections both in Bangladesh and India.
