ABSTRACT
Pr. mirabilis causes several infections in patients with 'complicated' urinary tract infections. In cases where stones are formed, the bacteria can become resistant to antibiotics. Pr. mirabilis can be diagnosed in the laboratory due to its characteristic swarming motility, and inability to metabolize lactose on a MacConkey agar plate. The identification and antibiotic sensitivity of hundred and two urine samples [38 males, 64 females] with urinary tract infection [UTIs] were investigated. Sixty samples, [59%] had associated urinary tract infection with Pr. mirabilis which has the most common causative microorganism. The bacterial isolates altered in their susceptibility to antimicrobial agents. Indole test, methyl red test, trytophan test, oxidase test, and casein test were appeared to be negative but the catalase test, phenylalanine deaminase test, urea test, hydrogen suflide test and citrate agar test were exerted a positive results
