Analysis of Characteristics of Bovine-Derived Non-Enterotoxigenic Bacteroides fragilis and Validation of Potential Probiotic Effects.

ABSTRACT: Bacteroides fragilis is a new generation of probiotics, and its probiotic effects on humans and some animals have been verified. However, research on B. fragilis in cattle is still lacking. In this study, 24 stool samples were collected from two large-scale cattle farms in Wuzhong, Ningxia, including 12 diarrheal and 12 normal stools. A non-toxigenic Bacteroides fragilis (NTBF) was isolated and identified by 16S rRNA high-throughput sequencing and named BF-1153; genome composition and genome functional analyses were carried out to reflect the biological characteristics of the BF-1153 strain. A cluster analysis of BF-1153 was performed using Mega X to explore its genetic relationship. In addition, Cell Counting Kit-8 (CCK8) was used to determine the toxic effects of the
