Agar (disk) diffusion test susceptibility of clinical isolates of Pseudomonas aeruginosa to azlocillin, cefotaxime, cefsulodin, lamoxactam, mezlocillin, and piperacillin. 1982

W H Traub

The standardized Bauer-Kirby agar diffusion test served to examine 100 clinical isolates of Pseudomonas aeruginosa against various recently introduced broad-spectrum penicillins and cephalosporins. Neither cefotaxime nor lamoxactam displayed significant activity against this microorganism. Azlocillin, cefsulodin, and piperacillin were significantly more effective (p less than 0.0001) than mezlocillin against the majority of isolates. When compared individually, azlocillin and piperacillin displayed comparable in vitro activity; the same was true for cefsulodin compared with piperacillin. On the other hand, cefsulodin was somewhat more active than azlocillin (p less than 0.05, greater than 0.01) against P. aeruginosa. These data should enable diagnostic laboratories to curtail the number of antimicrobial drugs routinely utilized to examine clinical isolates of P. aeruginosa for antibiotic susceptibility, i.e., piperacillin exclusively.

D009070	Moxalactam	Broad- spectrum beta-lactam antibiotic similar in structure to the CEPHALOSPORINS except for the substitution of an oxaazabicyclo moiety for the thiaazabicyclo moiety of certain CEPHALOSPORINS. It has been proposed especially for the meningitides because it passes the blood-brain barrier and for anaerobic infections.	1-Oxacephalosporin,6059-S,Disodium Latamoxef,Disodium Moxalactam,Festamoxin,Lamoxactam,Latamoxef,Lilly 127935,Ly-127935,Ly127935,Moxalactam Disodium,S-6059,Shiomarin,1 Oxacephalosporin,6059 S,6059S,Disodium, Moxalactam,Latamoxef, Disodium,Ly 127935,Moxalactam, Disodium,S 6059,S6059
D010406	Penicillins	A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.
