A Study on Isolation of E. Coli Bacteria from Different Human Clinical Specimens

E.coli is a gram negative bacillus found in the human and animal gut and is the leading cause of Urinary tract infections and various other infections and complications. This is a retrospective study comprising of 1040 human clinical specimens of urine, pus, blood and sputum received over a period of six months in our hospital which came for culture and sensitivity. Out of these specimens 5.09% total specimens, 8.9% urine specimens, , 5.2% pus specimens, 0.8% blood specimens and 1.5% sputum specimens were positive for E. coli growth. We also checked for drug sensitivity of various drugs and found out that Aminoglycosides, Carbapenems, Fosfomycin, Colistin and Nitrofurantoin showed good sensitivity against E. coli. From our study we concluded that E. coli is a common cause for urinary tract infections and wise usage of antibiotics should be done to prevent the growing problem of antibiotic resistance.
