because this impact on the physiological balance is known to be causative for severe nosocomial infections and is mainly seen with antibiotics that are massively excreted via the bile ( e.g . broadspectrum penicillins , ceftriaxone and cefoperazone ) , we investigated cefotaxime ( ctx ) , cefotiam ( ctm ) , cefmenoxime ( cmx ) , ceftazidime ( caz ) , ceftizoxime ( czx ) and cefazolin + netilmicin ( cez + ntl ) in healthy volunteers .
