Role of a sugar-lipid intermediate in colanic acid synthesis by Escherichia coli.

abstract：:Bacteroides fragilis V479-1 (also designated strain 92) has previously been shown to contain a conjugative plasmid, pBF4, that specifies resistance to clindamycin (Cc). A report of inducible tetracycline (Tc) resistance in this strain suggested that this phenotype was also plasmid associated (G. Privitera et al., Natu...
