Cutaneous alternariosis is an infectious disease mainly of camel calves of approximately one year of age and the incidence decreases with the advancement of age.

The disease occur more frequently in semi arid than arid region of the state. Lesions of the disease are found anywhere on the body including the lips and udder. This disease may be quite confusing with other dermatophyte infections. Repeated culture of skin scrapings lead to isolation of Alternaria alternata.
