Besnoitia

A genus of sporozoan parasites in the family Sarcocystidae and they are relatively host specific. There are a number of species that are found only in wild animals. Horses and cattle are affected by disease in their role as intermediate hosts. In many of the species the definitive host is the cat. In the others the definitive host has not been identified.

• B. bennetti — causes besnoitiosis of horses and donkeys.
• B. besnoiti — causes besnoitiosis of cattle.
• B. caprae — found in goats.
• B. darlingi — found in opossums, possibly lizards.
• B. wallacei — found in cats.

Besnoitia is a genus of Apicomplexan parasite.

Life cycle

The life cycle of many of the species in this genus are not known but it's probably complex with various intermediate hosts and many vectors (stomoxys sp., tabanidae...)

Pathology and effects on the host

Infection with these parasites causes pedunculated lesions in the skin, nasal cavity and larynx of domestic animals. The lesions consist of exophytic nodules protruding from mucosal surfaces.
