Re-evaluation of lunation of the activity of somantibacterial drugs against clinical isolates of Escherichia coli in al- najaf al- ashref governorate

Abstract

ackground: Escherichia coli is one of the most
important bacterial pathogen that can cause several
disease to human being . In our study we try to
investigate the sensitivity resistance pattern of
Escherichia coli against three antibiotics ( Amikacin,
Nalidixic acid and Cephalexin).
Methods: For this purpose we collected 51 clinical
isolates of Escherichia coli from stool and urine of
outpatient and inpatient patients from different wards
of AL-SADER Teaching Hospital in AL-NAJAF
AL-ASHRAf, IRAQ, and tested by culture and
sensitivity test .
Results: The results appeared that Amikacin show
the highest percentage of sensitivity ( 66.66 % ) ,
while Cephalexin show the lowest percentage of
sensitivity ( 6.34 % ) .
Conclusions: we conclude that Amikacin is the most
sensitive antibacterial drug for Escherichia Coli as
compared with Nalidixic acid and Cephalexin, while
Cephalexin is the most resistant antibacterial drug
for Escherichia Coli as compared with Amikacin and
Nalidixic acid.
