A total of 100 eggs tifty each from ducks and hens were examined for the presence of Salmonella on the shells. Of the 50 duck egg shell samples, 7 were/found positive (14%) while in case of hen eggs only 2 samples (4%) were positive for S. enteritidis (antigenic structure 9. 12: g-m-). These Salmonella enteritidis isolates were tested in-vitro for antibiotic sensitivity and the results indicated that all of the isolates were sensitive to gentamicin (100%) folllowed by streptomycin and ciprofloxacin (88.9% each), cephalexin and ciprofloxacin (77.8%), cloxacillin (55.6%), nalidixic acid (55.2%) and all isolates were resistant to penicillin, while sensitivity to tetracycline and doxycycline varied.
