cutaneous stephanofilarosis

infestation with Parafilaria multipapillosa causes subcutaneous nodules in horses, P. bovicola causes similar lesions in cattle, Suifilaria suis does the same in pigs, Stephanofilaria dedoesi causes dermatitis in cattle (cascado). S. kaeli and S. assamensis cause dermatitis in cattle (humpsore), S. zaheeri causes contagious otorrhea (earsore), a dermatitis around the ear in buffalo, S. stilesi and S. okinawaensis also cause dermatitis in cattle.

The dermatitis is manifested by small papules that enlarge to form itchy, scabby lesions that suffer much rubbing. The lesions occur at various sites on the body depending on the species of worm. See parafilaria, stephanofilaria, elaeophoraschneideri.
