Use of a probiotic escherichia coli isolate for the inhibition of shiatoxinproduktion and the growth of enterohaemorrhagic escherichia coli (ehec) - strains

摘要

A probiotic e. coli o15: h - strain is described, for which none of the pathogenic e. coli known genes (for enterotoxin, shiga toxin, no eaea, ipah, asta, = - hly, ehx, pap, slcds - fimc) and which is capable of the shiga toxin production enterohemorrhagic e. coli (ehec) or their growth in bouillon cultures and in the stool inhibit. The probiotic e. coli, h 2 s, cleaves, however, in the h 2 s - positive and h 2 s - negative colonies, both of which are equally effective. The probiotic effect on the shiga toxin production or the growth of the ehec - strains is mixed with fresh bacteria cultures and after lyophilization of the probiotic e. coli - strain is achieved.
