Background
and objectives:
Urinary tract infection is one of the most
nosocomial infections with different antibiotic resistance pattern. This study
was aimed to investigate the pattern of susceptibility and resistance of
uropathogenic E. coli strains that had been isolated from those who referred to
the private laboratories in Khorram-Abad city.
Materials and Methods: This empirical study was conducted on 253 urinary
strains. After identification of the strains. by standard biochemical tests,
the pattern of the susceptibility of bacterial strains was investigated by
Kirby - Bauer Disk Diffusion Susceptibility Test according to Clinical and
Laboratory Standards Institute,( CLSI).
Results: The most resistant strains were
for co-trimoxazole (61.26%), ampicillin (52.57%), cephalexin (49.01%),
nalidixic acid (44.26%), respectively. On the other hand, the most sensitive to
antibiotics were nitrofurantoin (83.79%), amikacin (79.05%), enrofloxacin
(68.77%) and ciprofloxacin (65.61%), respectively.
Conclusion: Based on the results of this study, it is suggested using nitrofurantoin and
amikacin as the first antibiotics for the treatment of uropathogenic
E.coli infections and co-trimoxazole and ampicillin should be avoided.
Key words: Antibiotic
resistance, E.coli, Urinary infections.
Funding: This
project was financially supported by the Faculty of Veterinary Medicine,
University of Lorestan.
Conflict of interest: None declared.
Ethical approval: The Ethics Committee of the University
of Lorestan approved the study.
