Preventive activity of Streptococcus viridans (Ab1III) against artificial colonization of pathogenic beta-hemolytic streptococci in rabbits.
A Streptococcus viridans strain (Ab1III) with a strong interfering activity against pathogenic beta-hemolytic streptococci in vitro was stuided for its inhibiting activity in vivo. Implantation of this strain into the oropharynx in rabbits provided them with complete resistance against artificially induced colonization of the upper respiratory tract by pathogenic beta-hemolytic streptococci.
