Abstract

The in vitro growth of Streptococcus mutans was completely inhibited by water-soluble extracts from cells of various intestinal lactic acid bacteria identified as Streptococcus faecium, Streptococcus equinus, Lactobacillus fermentum, and Lactobacillus salivarius. The growth inhibition was dependent on the concentrations of the extracts. In contrast, the extracts did not inhibit the growth of the major indigenous intestinal lactic acid bacteria isolated from humans. These lactic acid bacteria were not acutely toxic in mice.

摘要

被鉴定为粪肠球菌、马肠球菌、发酵乳杆菌和唾液乳杆菌的各种肠道乳酸菌细胞的水溶性提取物可完全抑制变形链球菌的体外生长。生长抑制取决于提取物的浓度。相比之下,这些提取物并未抑制从人类分离出的主要肠道原生乳酸菌的生长。这些乳酸菌对小鼠无急性毒性。
