Comparison of Regulated Parasitic Diseases of Cattle, Sheep, and Goats with Camelids

Regulated Parasitic Diseases of Cattle and Sheep	Etiology	Status in Camelids	Intermediate Hosts	Location in Host
Screwworm myiasis	Cochliomyia hominivorax or Chrysomyia bezziana	All animals, including camelids, may become infested with screwworms.	None	Wounds, necrotic tissue
African trypanosomiasis (surra)	Trypanosoma evansi	Important disease of camels; may involve other species of Trypanosoma.	Blood-sucking flies (tabanids, Stomoxys), tsetse flies, and other	Blood
		SACs also infected.
Bovine babesiosis (piroplasmosis)	Babesia bovis	No verified reports in either camels or SACs	Ticks	Blood
Theileriosis (East Coast fever, corridor disease)	Theileria spp.	No verified reports in either camels or SACs	Ticks	Blood
Cattle scabies (multiple types)	Sarcoptes scabiei, Psoroptes ovis	Both may infest camelids.	None, direct contact	Skin
Sheep scabies	Psoroptes ovis	Yes	None, direct contact	Skin
Echinococcosis (hydatid disease)	Echinococcus granulosum	Many species, including camelids	Carnivore is primary host; herbivores are intermediate host.	Variable, but liver and lungs common
