susceptibility testing to four additional beta-lactams ( cefoxitin , cefuroxime , cefotaxime , and piperacillin ) and to four aminoglycosides ( gentamicin , tobramycin , amikacin , and netilmicin ) indicated that antibiotic resistance was widespread and in all species more frequent among methicillin-resistant than among methicillin-sensitive staphylococci .
