title: Protective activity of Streptococcus faecalis against pathogenic action of Escherichia coli O55 in gnotobiotic pigs.
abstract: Peroral administration of Streptococcus faecalis suppresses the lethal effect of simultaneous or subsequent infection with pathogenic Escherichia coli O55 in gnotobiotic colostrum-free piglets. The presence of S. faecalis in the intestine and mesenteric lymph nodes in artificially diassociated colostrum-free piglets influences neither multiplication of E. coli in the intestine nor its penetration into the organism.
