Antibiotics are being used to treat bacterial infections worldwide. Extensive and unchecked use of these antibiotics helps to develop resistance in microbes which
is a growing issue for the medical specialists to treat different infections. To evaluate antibiotic resistance almost 125 samples were collected from different instruments of various institutional laboratories. Different microbes were isolated by using different culture media and further identified by biochemical characterization. Out of all isolated bacteria, only Escherichia coli (E. coli) were selected for antibiotic susceptibility. In the present study six antibiotics (colistin, norfloxacin, neomycin, chloramphenicol, nitrofurantoin and trimethoprim) were applied on the isolates of E. coli. 90% of the isolates of E. coli showed sensitivity or susceptibility towards chloramphenicol. It was concluded that chloramphenicol is the most effective antibiotic in treating the infections
caused by E. coli.
