An unusual case of dermatophilosis in a calf

Abstract

Extract

Dermatophilus congolensis is recognized as the cause of “cutaneous streptothricosis” in cattle — an exudative dermatitis resulting from infection of the superficial layers of the epidermis (as deep as the stratum granulosum). Acute fulminating infections resulting in death are seen, as also are fatal complications such as necrotic or gangrenous dermatitis resulting from secondary bacterial infection (Jubb and Kennedy, 1970). A range of inflammatory proliferative lesions of the tongue have been reported also from cases of streptothricosis (Mornet and Thiery, 1955). With the exception of granulomatous lesions of the posterior oral cavity in cats (O'Hara and Cordes, 1963; Baker etal., 1972) infections of other sites with D. congolensis do not appear to have been reported.
