despite differences in behaviour ( cefotaximase and ceftazidimase phenotypes ) , resistance to amino- , carboxy- and ureido-penicillins is associated with reduced sensitivity or resistance to oxyimino beta-lactams ( cefotaxime , ceftriaxone , ceftazidime , aztreonam ) , but cefamycins and imipenem are untouched .
