Assessment of ß-lactams and Carbapenems Antimicrobials Resistance in Isolated from Patients with Urinary Tract Infections in Najaf, Iraq.

Antimicrobial resistance is becoming an arising global issue. Until recent years, more than 50% of commercially available antibiotics were ß-lactam. Pathogenic bacteria which are resistant to antibiotics include all ß-lactams except for cephamycin and carbapenems. This study aimed to evaluate some ß-lactams and carbapenems antimicrobials resistance in . In total, 177 urinary tract infection samples were collected for the purposes of the study. Isolates were identified using morphological features and routine biochemical testing. All isolates were tested for susceptibility to 11 antibiotics using the usual disc diffusion method. The result showed that 155 (87.57%) and 20 (11.29%) out of 177 collected urine samples were gram-negative bacterial isolates and gram-positive bacterial isolates, respectively. The findings also showed that there were two samples (1.12 %) with no growth. The results proved no susceptibility to Ampicillin, Cloxacillin, Ceftazidime, Penicillin, Piperacillin with a resistance rate of 100%.
