Abstract:
This study evaluated the epizootiological characteristics of equine coital exanthema (ECE) in South Korea. A PCR test was used to determine the equine herpesvirus 3 (EHV-3) release period, excretion by suckling foals, morbidity rate, effect on fertility, and onset of breeding partner after treatment. The morbidity rate of ECE based on clinical symptoms was 8.3% (2/24) for stallions and 10.8% (45/416) for mares, and 29 of 45 (64.4%) animals were positive on the PCR test. Ten (22%) broodmares had symptoms before breeding, while 26 (58%) had symptoms after breeding. Nine (20%) mares had uncertain coverage periods and occurrence times. Suckling foals had no clinical findings and EHV-3 was not detected in their nostrils, although it was detected on teasers. No lesions were observed in the clitoral fossa on broodmares, although EHV-3 was detected by PCR. The period of EHV-3 emission was 22~23, 18~19, 6, and 58 days in stallions, broodmares, teasers, and mares with a mixed E. coli-like infection, respectively. ECE had no negative effects on the breeding capability of stallions and no symptoms were observed in broodmares after recovering from ECE.
