Abstract
Abstract: This study focuses on isolating and identifying 17 strains of Proteus mirabilis from a total of 135 clinical samples obtained from patients who visited Hila Teaching Hospital between October 2014 and February 2015. The isolates collected from patients diagnosed with urinary tract infections accounted for 11 cases or 64.7% of the total. In contrast, patients with ear infections contributed 3 cases, making up 17.6% of the total. In addition, the isolates acquired from patients with diarrhea, wound, and vaginal infection each accounted for 1 (5.9%) of the total cases. The collected isolates have been cultivated on specialized media and identified using biochemical reactions.
 Some virulence factors of all isolates are studied, and the results showed that all bacterial isolates 17(100%) produced hemolysin, urease, Bacteriocin (proticin), and swarming, while 16(94.1%) of isolate produced beta-lactamase. Antibiogram of P. mirabilis isolates has been studied and it has been found that all isolates were entirely resistant to Imipenem 17(100%), while most of the P. mirabilis isolates were sensitive to Ertapenem so the resistant only 3(17.6%). Furthermore, the resistance of isolates to Amoxicillin and Cefotaxime 14(82.3%), also 9(52.9%) of them were resistant to Amoxiclave, 11(64.7%) of them were resistant to Ceftriaxone and 4(23.5%) of them were resistant to Cefepime Clavulanic acid.
