How is CEM diagnosed in females and in males?

Contagious equine metritis is a sexually transmitted infection, so the diagnostic approach relies on where the organism can be detected in the genital tract and whether transmission occurs. For females, sampling the clitoral sinuses and fossa and culturing for Taylorella equigenitalis is the standard way to confirm infection because these sites commonly harbor the organism in mares with CEM. For males, many carriers harbor the organism on the penis/prepuce with intermittent shedding, so a practical test of carrier status is to breed the stallion to a clean mare and then culture the mare after mating. If the mare becomes infected, it indicates the stallion is a carrier.
