Abstract

ABSTRACT:
BACKGROUND:
The genus Hafnia , a member of the family Enterobacteriaceae, consists of Gram negative bacteria
that are occasionally implicated in both intestinal and extraintestinal infections in human. This genus
contains only a single species (Hafnia alvei).
METHODS:
The above bacterium was identified from 250 bacterial strains which were isolated from 220 urine
samples of patients with urinary tract infection.
RESULTS:
One H. alvei strain was isolated from an elderly patient, and identified by conventional biochemical
tests and API20E system at the first time in Iraq. Antimicrobial susceptibility test showed that this
strain is sensitive to Cefotaxime, Ciprofluxacine, Chloramphenicol, Doxycycline and Trimethoprimsulfamethaxzole,
while it is resistant to Penicillin, Oxacillin and Amoxicillin plus clavulanic acid.
CONCLUSION:
H. alvei an important uropathogen that causing urinary tract infection in elderly and may be in
immunocompromised patients.
