Abstract

Objectives: The study was designed for isolation and identification of the bacteria present in unhatched leftover eggs of duck in selected mini-hatcheries of Kishoreganj, Bangladesh.

Materials and Methods: A total of 54 unhatched discarded eggs were collected as samples from different mini-hatcheries of Tarail and Itna Upazilas of Kishoreganj and aseptically carried to the laboratory in the icebox. Surface washings (n = 54) and inner contents (n = 54) were collected and enriched in Luria–Bertani broth followed by the isolation of pure colonies of different bacte­ria onto eosin methylene blue agar, mannitol salt agar, Salmonella–Shigella agar, and blood agar plates. Identification of the bacterial isolates was done by cultural properties, staining, and bio­chemical tests followed by molecular detection by Polymerase chain reaction.

Results: Of 108 samples, 62 were found positive for Salmonella spp. (76%), 59 for E. coli (54%), 52 for Staphylococcus spp. (48%), and 5 for Clostridium spp. (9%). From the egg surface sam­ples, Staphylococcus spp. were recovered in the highest (67%) followed by Salmonella spp. (59%), E. coli (56%), and Clostridium spp. (9%). From the inner contents of eggs, Salmonella spp. were recovered in the highest (56%), followed by E. coli (53%) and Staphylococcus spp. (30%).

Conclusion: The isolated bacteria might be associated with the decreased hatchability and embryo mortality in the mini-hatcheries of duck.
