Due to the intrinsic resistance that enterococci demonstrate towards many categories of antibiotics (e.g., penicillins), the most successful treatment has been glycopeptides. Glycopeptides cause bacterial cell death by perturbing the integrity of the cell wall. The most powerful glycopeptide, the so-called 'drug of last resort,' is vancomycin. However, the incidence of infections resistant to vancomycin has increased rapidly since 1988. Solving the problem of enterococcal resistance requires an understanding of the biosynthesis and organization of the cell-wall peptidoglycan, a potential binding site of vancomycin.
