Molecular investigation of phylogeny groups of Morganella morganii isolated from catheter associated UTI

Abstract EN

This study included, 100 urine samples obtained from patients suffering from Catheter-associated Urinary Tract Infection (CAUTI) and admitted to Hilla Teaching Hospital for Surgery for the period from October 2010 to February 2011 in Hilla city.

Out of 78 positive cultures, only three isolates showed positive for Morganella morganii (3.8 %), one from male and two from females.

Phylogeny markers used in detection of Morganella phylogeny were E.coli phylogeny markers.

These include yjaA, chuA and TspE4C2.

The results showed that one isolate was positive (amplicon) for yjaA, and two isolates for TspE4C2 but none of them was positive for chuA.

Since the isolates are positive to yjaA and TspE4C2.

So, they belong to phylogenitic group A and B1 respectively (intestinal group).

This may conclude that the Morganella source (in UTI) is intestinal.
