Molecular Detection of Equus caballus Papillomavirus Type 2 in Genital Swabs From Healthy Horses in the Republic of Korea

Equus caballus papillomavirus type 2 (EcPV-2) is implicated in genital neoplasms in horses, including equine penile papillomas, penile intraepithelial neoplasia, and squamous cell carcinoma (SCC). This virus seldom regresses spontaneously and can result in the development of SCC, which may result in significant clinical damage and economic cost. However, the prevalence of this virus is unknown in clinically unaffected horses. The aim of this study was to determine the prevalence of EcPV-2 DNA in genital swabs from healthy horses in the Republic of Korea and to investigate genetic variability within EcPV-2. A total of 797 genital swab samples obtained from Thoroughbred horses (35 stallions and 762 mares) were tested for the presence of the EcPV-2 gene E1 using a polymerase chain reaction (PCR) assay. Positive results were confirmed by repeat PCR to detect the presence of E6 and amplicon sequencing. Equus caballus papillomavirus type 2 DNA was detected in 1% (8/762) of mare swabs but in none of stallion swabs (0/35). All EcPV-2-positive mares had been imported from the United States. Equus caballus papillomavirus type 2 E6 gene sequences were used for phylogenetic analysis and revealed three subdivisions related to the European strains, and three isolates were located on two separate branches. This study documents the molecular prevalence and phylogenetic analysis of EcPV-2 DNA in the Republic of Korea.
