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.

Abstract
Getah virus (GETV), an arthropod-borne virus transmitted by mosquitoes, has been isolated from several animals. GETV infection in horses shows clinical signs such as fever, rash, and edema in the leg. Noma horses are one of the eight Japanese native horses. The present study aimed to clarify the occurrence of GETV infection in Noma horses. Serum samples collected from Noma horses were analyzed using a virus neutralization test and enzyme-linked immunosorbent assay and showed that the anti-GETV antibody titers in the samples collected in 2017 were significantly higher than those collected in 2012. We concluded that a seroconversion of anti-GETV antibodies was occurred in the Noma horse population around 2012, providing evidence of the GETV epidemic in Japan circa 2012.

Abstract
A vaccine for equine coronavirus (ECoV) is so far unavailable. Bovine coronavirus (BCoV) is antigenically related to ECoV; it is therefore possible that BCoV vaccine will induce antibodies against ECoV in horses. This study investigated antibody response to ECoV in horses inoculated with BCoV vaccine. Virus neutralization tests showed that antibody titers against ECoV increased in all six horses tested at 14 days post inoculation, although the antibody titers were lower against ECoV than against BCoV. This study showed that BCoV vaccine provides horses with antibodies against ECoV to some extent. It is unclear whether antibodies provided by BCoV vaccine are effective against ECoV, and therefore ECoV challenge studies are needed to evaluate efficacy of the vaccine in the future.
