Exudative epidermitis in pigs. Bacteriological studies on the causative agent.

The properties of six pathogenic and six non-pathogenic strains of staphylococci from clinical cases of exudative epidermitis are described. The pathogenic strains were shown to produce typical lesions following experimental inoculation of pigs. All of the strains studied were classified among the staphylococci due to their ability to produce acid from glucose under anaerobic conditions. One of the six pathogenic strains was a slow coagulase producer. It is suggested that the species designation Staphylococcus hyicus be retained.
