Abstract
Most antibiotics are used today are isolated and extracted from microbial source. The emergence of antibiotic resistance and need for better, broad spectrum antibiotics is always in high demand. Hence the present study was conducted to determine antibiotic sensitivity pattern of E.coli isolated from composite soil sample and identified by using the biochemical tests. Totally 25 antibiotics were used for the detection of antibiotic resistance profile of E.coli, antibiotics namely Ampicillin, Cephalothin, Streptomycin, Nitrofurantoin, Tetracycline, Chloromphenical, Amoxycillin clavunalic acid, Cefipirome, Cefpodoxime, Cefataxin, Nalidixic acid, Gentamycin, clindamycin, Doxycycline, Cefazolin, Levofloxacin, Meropenam, Lincomycin, Tobramycin, Vancomycin, Amoxyclave, Cephalexin, Norfloxacin, Colistin, Lemofloxacin. Antibiotic resistance was done by Kirby Bauer method.Ciprofloxacin and Vancomycin has showed the highest Zone of inhibition nearly 98%, After primary screening of antibiotic resistance E.coli showed antimicrobial activity against some bacteria and fungi namely Staphlococcus aureus (5.0mm), Pseudomonas aeruginosa(3.9mm), Klebsiella pneumonia(8.2mm), Pencilliumchrysogenum (12.5mm), Aspergillus species.(10.0mm), The results showed that Escherichia coli was commensal organism and exhibited multidrug resistances, necessitating efficient antibiotic stewardship guidelines to streamline their use in the production industry.
