Which of the following is a disease associated with equine?

Equine viral arteritis is a viral disease that affects horses, making it the relevant choice when discussing diseases specifically associated with equine species. This disease is caused by the equine viral arteritis virus (EAV) and primarily affects breeding stallions and their offspring, leading to significant economic impacts in the equine industry. It is characterized by fever, respiratory signs, and reproductive issues, such as abortion in pregnant mares.

The other options refer to diseases linked with different animal groups. Bovine trichomoniasis is associated with cattle, avian infectious laryngotracheitis pertains to birds, and scabies is a condition primarily affecting sheep and cattle. Therefore, equine viral arteritis stands out as the only condition specifically tied to horses, highlighting its relevance in equine veterinary medicine.
