Seroprevalence of canine coronavirus in domestic dogs in Ho Chi Minh City

Abstract

A total of 201 sera samples from CCoV unvaccinated dogs in Ho Chi Minh City were used for detecting antibody against CCoV-II. The studied results indicated that CCoV-II seroprevalence in the domestic dogs in Ho Chi Minh City was 43.3% (87/201). The result of analysing CCoVII seroprevalene by dog breed groups, age and sex showed that the exotic dog breed group
presented CCoV-II seroprevalence higher than that of the other dog breed groups. The CCoV-II seroprevalence of the dog group over 3 years old was higher than that of the dog group under one year old, there was no significant difference on CCoV-II seroprevalence found between the male and female dogs. The antigenicity between CCoV-Iib (CCoV/HCM47/2015) and the other
CCoV-Iia (fc1) was checked by PRNTt, as a result the antigenicity of the CCoV-IIb was higher than that of the CCoV-IIa (fc1)
