Vancomycin is one of the potent antibiotics to perturb the gut microbiota [1]. Vancomycin treatment caused a significant alteration in the composition and diversity of the commensal gut microbiota of the host[2].Vancomycin specifically blocks peptide cross-linking in the bacterial peptidoglycan by recognizing terminal peptide sequences and blocking their binding site to enzymatic cross-linkers. Vancomycin has previously been shown to be active against B. burgdorferi in vitro[5,6].
Low to moderate doses of vancomycin ( 2.0 µg/mL for 24 h) produced small alterations in cell shape and that as the dose was increased, cell speed decreased. Vancomycin concentrations >1.0 µg/mL also inhibited cell growth and led to bleb formation on a fraction of the cells[3]. The addition of vancomycin at a concentration of 10ug/ml-1 to the wash solution of the cell-saver achieved similar concentrations in the autologous blood concentrate recovered allowing for bacterial removal, with negative blood cultures in all cases[4].
Metagenomic analysis of gut microbiota revealed that the treatment with vancomycin caused a significant decrease in the relative abundance of Firmicutes and Bacteroidetes phyla with a time-dependent increase in Proteobacteria and Verrucomicrobia phyla. Maximum restoration (> 70%) of gut microbiota happened by the 15th day of withdrawal of vancomycin. BALB/c mice showed a more efficient restoration of gut microbiota compared to C57BL/6 mice[7]. Mice treated with vancomycin alone had a better clinical outcome in the treatment phase of CDI than mice treated with metronidazole alone[8].
