<i>In Vitro</i> Antimicrobial Sensitivity of <i>Escherichia coli</i> Isolated from Clinical Sources

Abstract

A study of antimicrobial sensitivity of Escherichia coli (E. coli) isolated from clinical sources
of different diagnostic centers of Dhaka, Bangladesh was carried out to facilitate the choice of drug
in the management of E. coli induced symptoms. Very low sensitivity of E. coli towards ampicillin
(4%), aztreonam (4%), cloxacillin (5%), nalidixic acid (5%), ciprofloxacin (7.5%), ceftriaxone
(12.5%), doxycycline (12.5%), ceftazidime (16.25%), co-trimoxazole (20%), chloramphenicol
(22.51%), tetracycline (25%), and netilmicin (35%) was observed. Higher sensitivity pattern was
observed for gentamicin (56%) and only imipenem (95%) showed sensitivity pattern possibly
susceptible enough to consider for the management of E. coli induced cases in the area under study.
The low sensitivity to different antimicrobial could be attributed to their prevailing usage and abuse
in the area under study.
