Synergism between β-Lactams and Glycopeptides against VanA-Type Methicillin-Resistant Staphylococcus aureus and Heterologous Expression of the vanA Operon
25 Oct 2006
Abstract excerpt
Vancomycin resistance of Staphylococcus aureus NY-VRSA and VRSA-5 is due to acquisition of a vanA operon located in a Tn1546-like element. The vanA gene cluster of NY-VRSA contained one copy of insertion sequences IS1251 and IS1216V relative to that of VRSA-5. As evidenced by the nature of the late peptidoglycan precursors and by quantification of d,d-peptidase activities, the vancomycin resistance genes were...
