| Abstract |
|
The serotypes and pathogenicity of 47 isolates of Erysipelothrix rhusiopathiae from pigs with acute septicemic swine erysipelas were investigated. The serotypes were determiend by agar gel precipitation test using autoclave extracted antigens. All of the 47 isolates(42 strains from Youngnam and fi fotrains from Kyunggi province) were serotype lao Five field isolates of Erhusiopathiae serovar la were tested for pathogenicity in mice. All of 5 selected isolates were pathogenic for mice and $LD_{50}$ was $3.7{ imes}10^3$ viable cells. Mice immunized subcutaneously with live vaccine did not die after challenge with virulent isolates of E rhusiopathiae. |
