Prevalence of serum and salivary virus-neutralizing antibodies against equine coronavirus in four riding stables in Japan.
Abstract: To assess the prevalence of equine coronavirus infection in riding horses, virus-neutralizing tests were performed on serum and saliva samples collected at four facilities in Japan. Seropositivity rates ranged from 79.2% to 94.6%, suggesting widespread circulation of the virus in these populations. Antibody prevalence in saliva samples from two facilities that had experienced outbreaks in the previous year (67.6% and 71.4%) was significantly higher than at the other facilities without reported outbreaks (41.7% and 45.2%, P<0.05). The presence of salivary antibodies in a high proportion of horses is therefore suggestive of recent exposure to the virus.

The research study investigates the occurrence of equine coronavirus in riding horses in Japan through tests on serum and saliva samples. The findings indicate that the virus is prevalent with seropositivity rates between 79.2% and 94.6%.
Objective of the Research
- The main objective of the study was to evaluate the prevalence of equine coronavirus infection in riding horses.
- The researchers performed virus-neutralizing tests on serum and saliva samples collected from horses at four different facilities in Japan.
Findings of the Study
- The study uncovered high prevalence rates of the virus ranging from 79.2% to 94.6%, providing evidence of widespread circulation of the virus in these horse populations.
- The level of antibodies in saliva samples from the two facilities that experienced outbreaks in the previous year (67.6% and 71.4%) was significantly higher than in the facilities without reported outbreaks (41.7% and 45.2%). This result suggests recent exposure to the virus in the facilities with outbreaks.
Significance of the Research
- The research offers crucial insights into the frequency of equine coronavirus in riding horses, confirming its widespread presence in Japan based on the analyzed samples.
- The study’s findings about the high presence of salivary antibodies in horses in facilities with recent outbreaks provides a window into how recent exposure to the virus can be determined.
