Isolation and characterization of Morganella morgana from alkaline urine

Abstract EN

A total of 75 alkaline urine samples obtained from patients with urinary tract infections, only six isolates of Morganella morgani were isolated.

All these isolates were urease producers, which was produced constitutively and was responsible for changing the pH of urine into alkaline.

Also, some isolates were able to produce haemolysin (two isolates), uronic acid (one isolates) and morganocin (one isolates).

Furthermore, Antimicrobiol sensitivity tests were performed on Morganella isolates and they showed high resistance rates against the commonly used antimicrobial agents: ampicilline, amoxicilline, trimethoprim, nalidixic acid & cephalexin, where as all isolates were sensitive at high rates to ciprofloxacin and cefotaxim which nowadays used successfully in treatment of UTI.

This work was the first one performed one Morganella morgani in Hilla province Iraq.
