Treatment of Ampicillin-Resistant Enterococcus faecium Urinary Tract Infections

Conclusion

Although this was a very small retrospective analysis, to the authors knowledge this is the first clinical study supporting the in vitro theory that amoxicillin (500 mg every 8 hours) may overcome the MIC of resistant isolates due to achievement of higher urinary concentrations. Because this was a small retrospective analysis, more prospective evidence is needed to confirm these results.
