The activity of methicillin, oxacillin, vancomycin, imipenem and FK037 against 106 isolates of staphylococci was assessed using a microbroth dilution method with low (10(5) cfu/mL) and high (10(7) cfu/mL) inoculum sizes. Overall, FK037, an oxime-type cephem antibiotic, was as active as imipenem, but less active than vancomycin (MIC90s 25, 25 and 6.25 mg/L, respectively) at the lower inoculum. E...
