Etiology of the ear necrosis syndrome – investigation of infectious agents

During the summer months lesions of the so-called ear necrosis syndrome can be observed frequently in weaners during the raising period. The stages range from mild epidermal changes to severe ulcers and necrosis (1). In the past, various pathogens have been discussed to be responsible for the development of ear necrosis, but the exact etiology of this disease could not be determined. Aim of this study was the evaluation of different infectious agents in pigs with ear necrosis syndrome.   C
