CA, community-acquired infection; HA, hospital-acquired infection; "-", not done. *E-test was used for susceptibility testing of enterococci against ampicillin, ciprofloxacillin, linezolid, quinupristin-dalfopristin, vancomycin and high-level gentamicin resistance. † Statistically significant difference in susceptibility among hospital-acquired and community-acquired isolates, p < 0.05 by two-sided Fisher's exact test.
