Resistance of methicillin-resistant Staphylococcus aureus isolates to clindamycin, ciprofloxacin, gentamicin, and sulfamethoxazole/trimethoprim in outpatient areas of hospitals, United States, 1999–2006. Multiple drugs indicates isolates that were tested against ciprofloxacin or clindamycin and >3 other drugs and found to resistant only to oxacillin. The p values were calculated by using the χ2 test. Differences in all comparisons were significant (p<0.001).
