Abstract
The sensibility of some Pseudomonas aeruginosa strains from urinary tract infections to antimicrobial agents. In the present paper we studied the sensibility and the resistance of 30 strains of Pseudomonas aeruginosa isolated from urinary tract infections at the following antimicrobial agents: azlocillin (AZ), mezlocillin (MZ). piperacillin (PIP), ticarcillin (TIC), cefoperazone (CFP), cefotaxime (CTX), ceftazidime (CAZ), ceftriaxon (CRO), cefuroxime (CXM), imipenem (1PM), cefalexin (CL). amikacin (AN). gentamicin (GM), netilmicin (NET). kanamicin (K). tobramicin (NN). ciprofloxacin (CIP), norlloxacin (NOR), ofloxacin (OFX). We used the Kirby-Bauer diffusimetric method, togetherwith the NCCLL recommandations and the rezults were calculated according to the critical diameter indicated by the antibiotics microdisk producer. We obtained the following results:
- among antipiocianic penicillins, azlocillin was the most efficient (80% sensitive strains);
- the association carboxi- and ureidopenicillins with beta-lactamase inhibitors increases their anti-microbial activity;
- among aminoglicosides, the most efficient were: amikacin (93,33% sensitive strains) and netilmicin (90%);
- among cephalosporins, the most efficient was cefalexine (90%), and between fluorquinolons, norfloxacin (93,33%).
