Despite of their nutritional values eggs can cause health problems through consumption of contaminated eggs with pathogenic microorganisms. Therefore, the present study was undertaken to identify <em>Escherichia coli </em>isolated from chicken eggs with their antibiogram assay in Rajshahi district of Bangladesh. <em>E. coli </em>was isolated from 180 chicken eggs collected from different areas of Rajshahi district and identified based on cultural, staining, and biochemical characteristics. Antibiogram assay of all the isolates were done by disk diffusion method. The overall prevalence of <em>E. coli </em>was 38.89% in chicken eggs of which 27.78% was on egg shells and 11.11% was in egg content. The prevalence of <em>E. coli </em>was 58.33% in commercial layer farm eggs, 41.66% in whole seller eggs, and 16.67% in retailer eggs. In antibiogram study, isolated <em>E. coli </em>showed 64.28% to 92.85% sensitivity to chloramphenicol, gentamycin, and ceftriaxone. The highest sensitivity was found to meropenem (100%). Isolated <em>E. coli </em>showed resistance to ciprofloxacin, tetracycline, amoxicillin, ampicillin, and erythromycin ranging from 50% to 71.42%. Judicious use of antibiotics and public awareness will help to reduce the development of antibiotic resistance.</p><p>J. Bio-Sci. 29(1): 123-133, 2021 (June)</p> ER -
