Abstrakt: Effects of each of three indigenous Lactobacillusgroups on other bacterial populations were separately investigated in gnotobiotic rats. In the wall of the non‐glandular part of the stomach, contents of the stomach and contents of the upper part of the small intestine, some pre‐associated indigenous bacteria were reduced to conventional population levels by introducing three groups of lactobacilli: Group I (Lactobacillus acidophilusand related strains), Group II (L. fermentum) and the groups mixed. However, no obvious reduction in cell numbers of the pre‐associated bacteria occurred in the case of Group III (L. murini).
