we also investigated susceptibility with disks containing 30 micrograms of each of cephalothin ( cf30 ) , cefoxitin ( fox30 ) , cefuroxime ( cxm30 ) , and cefotaxime ( ctx30 ) and 75 micrograms of cefoperazone ( cfp75 ) and determined by cluster analysis any correlation with the zone diameters obtained with p2 disks .
