Abstract
The Proteus, Morganella and Providencia (PMP) group is a distinct set of bacteria within the Enterobacteriaceae family. Out of (380) isolates from different clinical sources, isolation of PMP bacterial group depending on API 20E confirmatory test, Vitek-2 GN. Disc diffusion method & VITEK-2 compact system used to evaluate antibiotic susceptibility.The number of Proteus mirabilis which isolated from urine samples was(5.5% n=21), then from burn samples (2.3% n=9), pus &wound swabs was(1% n=4),stool (0.78 % n=3). Proteus mirabilis was the most commonly isolated species in PMP group at (9.7%) , while Morganella morganii was isolated from urine only at (2.1% n=8), Providence stuartii was isolated from stool and pus samples only at (0.5% n=2).. Proteus mirabilis exhibited resistance toward Ceftazidime (83.7%) Cefuroximea axetil, Nitrofurantion (81%,) Cefazolin, Trimethoprim-sulfamethoxazole (78%) Cefuroxime (75%,) Amoxicillin-Clavulanic acid, Ceftriaxone (70%) gentamicin Ciprofloxacin, (64,62%) Cefepime (59%), while sensitive toward Ertapime, Imipenem Meropenem, Amikacin, Erythromycin (71%, 65%, 60%,65% and 55%). While Morganella morganii shows resistance Amoxicillin-Clavulanic acid, Cefazolin, Cefuroxime, Cefuroxime axetil, Nitrofurantion at(100%), ceftazidime, Cefepime, (87%), Ceftriaxone, Ciprofloxacin(62.5%) and sensitive toward Ertapime, Amikacin Piperacillin-Tazobactam Erythromycin at (100%), Imipenem (62.5%), gentamcin(75%), Trimethoprim-sulfamethoxazole (62%) gentamicin (87%) . Providence stuartii shows high resistance to most antibiotic using in this study This resistance is may be due to its acquisition of resistance genes. The prevalence of infection in the PMP group due to longer hospital stays. Drug resistance was also more common in the PMP group.
