Stable Colonization of Orally Administered Lactobacillus casei SY13 Alters the Gut Microbiota.

ABSTRACT: The gut microbiota plays an important role in intestinal health. Probiotics such as Lactobacillus are known to regulate gut microbes and prevent diseases. However, most of them are unable to colonize their stability in hosts' intestinal tracts. In this study, we investigated the ability of Lactobacillus casei SY13 (SY13) to colonize the intestinal tract of BALB/c mice, after its oral administration for a short-term (once for a day) and long-term (once daily for 27 days) duration. Furthermore, we also evaluated the influence of its administration on the gut microbial structure and diversity in mice. Male BALB/c mice were gavaged with 108 colony-forming units (CFU) of SY13, and TaqMan-MGB probe and Illumina MiSeq sequencing were performed to assess the colonization ability and bacterial comm
