Plain-English summary
A 2-month-old foal had a sore on its nostril caused by a virus called equine coital exanthema virus, which is related to equine herpesvirus 3. This situation started when the foal's mother developed similar sores on her private parts after returning from a breeding facility. Just five days later, the foal showed a lesion on its nostril, indicating that the virus can spread between horses without direct mating. To confirm the diagnosis, lab tests are needed to tell this virus apart from others that can cause similar sores around a horse's mouth and nose. The treatment details and outcome for the foal were not provided in the study.
Abstract
The virus causing equine coital exanthema (equine herpesvirus 3) was isolated from a lesion on the nostril of a 2-month-old foal. One week after the mare had returned from a stallion station, vesicular lesions developed on her vulva. They were diagnosed clinically as coital exanthema, and 5 days later a lesion developed on the nostril of her foal. This case is an example of horse-to-horse transmission of coital exanthema virus without coitus. A laboratory diagnosis is necessary to differentiate viruses that cause vesicular lesions about the oral and nasal cavities of horses.
