In this study, we investigated the prevalence of Diarrhea pathogens in pet dogs referred to as Canine Parvovirus (CPV) and Canine Rotavirus (CRV)in western Taiwan using conventional polymerase chain reaction (PCR).Fecalsampleswere collected from240 dogs which have the symptomsofdiarrhea examined bythe veterinaryhospitals from March 2015 to March 2017.The PCR sensitivityof total DNAs extracted from 0.1g fecal samples rangedfrom 10ng to100 ng. The prevalence of CPV and CRV infections were23.3% (56/240) and 9.2% (22/240)respectively.The related analysis between prevalence rates and the epidemiological data of pet dogs were correlated with the age, season,area, vaccinationandbreed. The results showed that both the diseases have the highest occurrence in winter and spring, and the highest proportions might occur in puppies, suburbs and mixed-breed dogs. Non-vaccination dogs werethe most prone to Canine Parvovirus Enteritis.When dog puppies wereinfected with CPV, the mortality rate was high. Since Canine Rotavirus is a zoonosis, the more human being is exposed to it, the higher its occurrence will be. This study has providedthe clinical veterinarian the advancedability of both the diseasesdiagnosis and crucial information for prevention and control of Canine Parvovirus and Rotavirus diseases in Taiwan and neighborhood countries.
