At 20 strains of Erysipelothrix rhusiopathiae isolated from acute cases of the disease in swine, the biochemical reactions, the sensitivity to antibiotics and the pathogenic effect to experimental animals were studied. Furthermore it was determined the serotyping of the above strains. The results of the investigation pointed out that: The biochemical reactions of the strains did not appear to have significant deviation from the normal characteristics of the species. They showed a pronounced sensitivity to tylosin, gentamycin and ampicilline, but some strains were resistant to kanamycin, erythrocin, chloramphenicol and oxytetracycline too. All the above tested strains were found to be pathogenic to white mice (b.w.20 g), even in a dose of 5x10(exp 5) orgs/ml. All the 20 strains belonged to serotype A1
