Abstract | ||||
The present research work was conducted for the isolation and identification of the bacterial isolates causing failure of eggs to hatch. A total of 210 un-hatched broiler breeder’s eggs were collected from different hatcheries located at Giza Governorate, Egypt. In this study 6 species of bacteria were isolated and identified as Staphylococcus aureus, Escherichia coli, Salmonella species, Mycoplasma gallisepticum, Pseudomonas and Klebseilla species. The highest incidence rate of Staphylococcus aureus was in dead in shells (20%), Salmonella species were the most prevalent organisms isolated from exploders eggs and eggs with mid embryonic deaths with an incidence of 56.6 % and 50 %, respectively. The highest isolation rate of E-coli was detected in Exploders (36.6%), while Mycoplasma gallisepticum was isolated from dead in shells and pipped eggs with an incidence rate of 6.6%. Klebsiella and Pseudomonas were isolated from exploders and pipped with incidence rate of 13.3% and 3.3%, respectively. The results of this study would be helpful for prevention and control of bacterial causes of un-hatched broiler breeder's eggs. | ||||
