OKLAHOMA CITY -- State agriculture officials are warning horse breeders in the state of a rare and contagious disease that can cause infertility in mares.
Spokesman Jack Carson says Contagious Equine Metritis has been confirmed in Kentucky and one Oklahoma mare has been in contact with an infected stallion.
State Veterinarian Becky Brewer says the disease is no threat to humans but could affect the horse industry.
Brewer says the disease is spread between animals during breeding and breeders should be sure their artificial insemination equipment is thoroughly cleaned and disinfected after each use.
Infected horses can be successfully treated with antibiotics.
