The main causes of porcine arthritis as reported in previous studies were E. rhusiopathiae, Strep. Equisimilis and Mycoplasma spp. In recent years the number of condemnations from which swine erysipelas is diagnosed has decreased.From the report of the U.S.D.A. for the 1971 fiscal year (8), only 9 hogs and 3041 carcasses were condemned respectively on antemortem and postmortem examination because of swine erysipelas. In spite of the reduced incidence of erysipelas, the economic loss due to arthritis has remained the same. There-fore, this study was conducted to determine the types of microorganisms which are currently associated with swine arthritis.Cultural techniques were designed to investigate primarily the role of mycoplasma and secondarily Streptococcus spp. and Staphylococcus spp.
