Following necessary preparation, the samples were streaked onto various selective media like Salmonella-Shigella (SS) agar (for <em>Salmonella </em><em>spp</em>.<em>)</em>, Eosin Methylene Blue (EMB) (for <em>E. coli</em>), and Mannitol Salt (MS) agar (for <em>Staphylococcus</em><em> spp</em>.) respectively for isolation of bacteria. The bacteria were confirmed based on cultural and biochemical characteristics. Antibiotic sensitivity test of the bacterial isolates was performed using seven antibiotics (Ampicillin, Chloramphenicol, Ciprofloxacin, Gentamicin, Vancomycin, Kanamycin and Cephalexin) by following disc diffusion method.</p><p><strong>Results: </strong><em>E. coli</em>, <em>Staphylococcus </em><em>spp.</em> and <em>Salmonella </em><em>spp</em>. were isolated and identified from the duck egg samples. Prevalence of <em>E coli </em>in outer egg shell was 80%, whereas in inner egg shell and inner egg content, this prevalence was 20% and 10%, respectively. Similarly, the prevalence of <em>Staphylococcus spp. </em>was 75%, 17.5% and 7.5% in outer egg shell, inner egg shell and inner egg content, respectively. The prevalence of <em>Salmonella spp.</em> was 82.5% in outer egg shell, 22.5% in inner egg shell and 12.5% in inner content of egg. All these three bacterial isolates were sensitive to Ciprofloxacin and Gentamicin and resistant to Ampicillin and Cephalexin.</p><p><strong>Conclusion: </strong>The duck eggs harbor multi-drug resistant (MDR) bacteria which may impose public health hazards if these MDR bacteria are transferred to human through food chain.<strong></strong></p><p><span><a href="http://doi.org/10.5455/javar.2018.e253">http://doi.org/10.5455/javar.2018.e253</a></span></p> ER -
