Diphtheritic stomatitis

Diphtheritic stomatitis is a recently discovered disease and has thus far been reported only in Yellow-eyed penguins. Its symptoms are similar to human diphtheria and is characterized by infectious lesions in the mouth area that impede swallowing and cause respiratory troubles. The infection is caused by Corynebacterium amycolatum, an aerobic Gram-positive bacterium and mainly affects very young chicks. However, it seems likely that a triggering agent might be involved in which renders the corynebacterium a secondary pathogen.
