STUDIES FOR ANALYSIS OF ENTEROTOXIN FORMATION AND PERMEABILITY FACTORS IN STREPTOCOCCI OF VETERINARY PATHOGENICITY

Studies were conducted into 59 streptococcal strains pathogenic to ani mals, with the view to obtaining insights into enterotoxin buildup and the presence of permeability factors. Neither the baby mouse nor the rabbit loop test provided evidence to presence of enterotoxin in 29 or nine strains. A permeability factor was recordable from 16 in 59 stra ins, among them nine Sc. agalactiae strains. Permeability factor were present but were not thermally stable in six strains. In another ten s trains, permeability factors retained their activity potentials even a fter 30 minutes of boiling.
