An outbreak of a mixed infection of Dermatophilus congolensis and Microsporum gypseum in camels (Camelus dromedarius) in Saudi Arabia.

Abstract

Although both Dermatophilus congolensis and Microsporum gypseum infections have been reported separately in camels, mixed infection involving both agents has not been reported to date. The authors describe a mixed infection of D. congolensis and M. gypseum in camels reared on a dairy farm in Saudi Arabia. A total of 131 out of 559 camels (23.4%) were affected. Forty-eight camels less than one year of age had discrete, circumscribed, crusty, hairless lesions, found in particular on the neck and forelegs. Eighty-three camels of varying ages had extensive hair matting with crusty, hairless lesions, especially on the flanks. Camel calves and young camels demonstrated a relatively greater amount of skin lesions. D. congolensis and M. gypseum were diagnosed by direct microscopy, isolation and histopathology.
