Zygomycosis causes

Zygomycosis usually is a disease of the skin, but can also occur in the sinuses or gastrointestinal tract. Zygomycosis caused by Mucorales causes a rapidly progressing disease of sudden onset in sick or immunocompromised animals. Entomophthorales cause chronic, local infections in otherwise healthy animals. The important species that cause entomophthoromycosis are Conidiobolus coronatus, C. incongruous, and Basidiobolus ranarum. Conidiobolus infections of the upper respiratory system have been reported in humans, sheep, horses, and dogs, and Basidiobolus has been reported less commonly in humans and dogs.^[1] Horses are one of the most common domestic animals to be affected by entomophthoromycosis. C. coronatus causes lesions in the nasal and oral mucosa of horses that may cause nasal discharge or difficulty breathing. B. ranarum causes large circular nodules on the upper body and neck of horses. Entomophthorales is found in soil and decaying plant matter, and specifically Basidiobolus can be contracted from insects and the feces of reptiles or amphibians. Zygomycosis of the sinuses can extend from the sinuses into the orbit and the cranial vault, leading to rhinocerebral mucormycosis.
