Abstract

Dermatitis is a major cause of mortality and down-grading of broiler-age chickens in the Southeast. Dermatitis affecting the unfeathered areas of chickens has been described (1,2,3). Frazier et al. (4) and Sanders et al. (5) described a severe gangrenous dermatitis of bacterial etiology involving both the feathered and unfeathered parts of broiler-age chickens. Also frequently seen as causes of dermatitis in broiler-age chickens are nutritional deficiencies and genetically slow feathering of male chickens (6). Dermatitis caused by mycotic agents has not been well documented. A dermatomycosis affecting the feathered and unfeathered areas of chickens and turkeys has been reported (7). Beemer et al. (8) described an epizootic of dermatitis produced by Rhodotorula mucilaginosa on a poultry farm in Israel. A similar outbreak involving Rhodotorula glutins in broiler-type chickens in the southeastern United States is reported here.
