A total of thirty normally quail birds were bought from local market in Mosul city in the period from September-October 2011. Quail birds were slaughtered and samples taken aseptically from internal organs of each bird for bacteriological investigation. The result showed isolation of 203 bacterial isolates from different organs of quail birds. The isolates ranged from Corynebacterium spp. 29.6 % (60 isolates) as a high percent, then E. coli 18.2% (37 isolates), Staphylococcus aureus 16.3 %(33 isolates), Bacillus spp. 14.8% (30 isolates), Enterococcus faecalis 9.9% (20 isolates), Klebsiella pneumoniae 6.4% (13 isolates), Proteus spp. 1.9% (4 isolates), Pasteurella multocida 1.9% (4 isolates) and Coagulase -vestaphyloco-ccus 1% (2 isolates). This study showed Corynebacterium spp. and E. coli were dominant bacteria in the internal organs of quail birds. Many studies reported that quail birdswere resistant to many bacterial diseases, so that these birds may act asmechanical transporting for different bacterial species to humans and animals with the risky of transporting of resistance bacterial species for many antibiotics.
