Seventy strains of pseudomonas aeruginosa isolated form clinical samples of hospital-infected cases were tested for sensitivity to cerftazidime, cefotaxime and cephazoline. Five strains (7%) were resistant to ceftazidime, 28 (40%) to cerfotaxime and 56 (80%) to cephazoline, MIC of ceftazidime for the resistant strains was 4.0 mg/L, whereas the sensitive strains were inhibited by 0.5-1.0 mg/L of the drug. Thirty four percent of the strains were betalacamase producers. In vitro cephalosporin resistance was compared to that of aminoglycosides viz. gentamicin (39%), sisomicin (57%) and tobramycin (45%).
