Orientations of the seven invertible polysaccharide biosynthesis locus promoters of Bacteroides fragilis were determined from bacteria grown in vitro, from feces of monoassociated and complex colonized mice, and from B. fragilis-induced murine abscesses. Bacteria grown in vivo have greater variability in orientation of polysaccharide locus promoters than culture-grown organisms.
脆弱拟杆菌 7 个可反转聚糖生物合成基因座启动子的取向,通过体外培养的细菌、单定植和复杂定植的小鼠粪便以及脆弱拟杆菌诱导的鼠脓肿进行了确定。与体外培养的生物体相比,体内生长的细菌在聚糖基因座启动子的取向方面具有更大的可变性。
