Serologic studies on porcine strains of Haemophilus parahaemolyticus (pleuropneumoniae): extraction of type-specific antigens.


By the use of phenol water extraction it was possible to obtain strictly serotype-specific antigens from mucoid cell cultures of five serotypes of Haemophilus parahaemolyticus (pleuropneumoniae). These serotype-specific antigens did not cross-react with each other in immunodiffusion tests. The type-specific precipitating phenol-water-fractions were composed… (More)
