Prevalence of aminoglycoside-modifying enzymes genes among isolates of Enterococcus faecalis and Enterococcus faecium in Iran.

Disks containing 120 microg of gentamicin were used to detect high-level gentamicin-resistant phenotype (HLGR) among isolates of Enterococcus faecalis (n = 79) and E. faecium (n = 35). These isolates were collected from three hospitals in Tehran during 2002-2004.
