[4] P. equorum is one of the few parasites where a natural immunity develops in the host. [3] However, when an infection is found in an adult horse, both the worm and egg counts are substantially low ...

[35] [36] This disease caused by T. equigenitalis is a concern in the equine industry, especially the professional industries of the Thoroughbreds and American Quarter Horses.

A mature sporangium of a Mucor sp. fungus. Usually, zygomycosis is a disease of the skin, but can also occur in the sinuses or gastrointestinal tract.
