ANTIMICROBIAL SENSITIVITY PATTERN OF E.COLI IN URINARY TRACT INFECTION- A RETROSPECTIVE ANALYSIS
Abstract
Aim- To determine the current trends in
antibiotic susceptibility pattern of E. coli at
a tertiary care hospital in, in- patients with
urinary tract infections. Materials and
methods- A retrospective analysis was
done in Tirunelveli Medical College Hospital
on 3581 urine culture reports issued for
suspected urinary infections in, inpatients
of the hospital during a 6months period.
The common microorganisms causing urinary
tract infections and microbial drug
sensitivity pattern were analyzed on 578
samples which were found to be culture
positive. Results- The common uropathogen
identified was E.coli (38.2). The frequency
of urinary infections in percentage
was more in the age groups 0-9years
(10.2) 50-59years (9.6) in males whereas
in females it was more in the age group of
20-29(14.8). The aminoglycoside antibiotic
amikacin showed the highest sensitivity
(94.19) towards E.coli and cotrimoxazole
showed the least sensitivity
(15.9).Conclusion- E.coli is the predominant
uropathogen identified in our hospital,
showing the highest
sensitivity to the amino glycoside, amikacin
and the least sensitivity to cotrimoxazole.
