Comparison of antimicrobial susceptibility of wild-type S. aureus ATCC 13709 (hatched bars) and 5e-resistant organism (solid bars) to a range of bacteriostatic antibiotics with known mechanisms of action, and 5e. Bacteriostatics include trimethoprim and sulfamethoxazole (dihydrofolate reductase pathway), doxycycline and amikacin (30S ribosomal subunit), chloramphenicol (23S ribosomal subunit), erythromycin and tylosin (50S ribosomal subunit), nisin (lipid II), nitrofurantoin (bacterial DNA); also included were the bactericidal controls, ciprofloxacin, amoxicillin, and cefotaxime.
