Existence of Campylobacter species that colonize quail gastrointestinal tract raised and slaughtered as a source of food for human consumption were studied. The higher the frequency of isolation was obtained from intestinal tract & cecum, coloacal swabs, and liver in order. Percentage of isolation of Campylobacter jejuni was 16-18% from intestinal tract, 10-14% from coloacal swabs and 4% from liver. Isolation was done from different ages (6-24 weeks old) investigated in this study. C. jejuni was the only identified Campylobacter species during this study. Time to death of chicken embryo in case of yolk sac inoculation ranged from 48-60 hours post-inoculation, and 48-72 hours post-inoculation in case of chorio-allantoic membrane (CAM) route. Died embryos showed severe enlargment and congestion of yolk sac, curling and focal hepatic involvment in case of yolk sac route. Severe congestion and enlargment of liver as well as congestion of embryos in case of CAM infected embryos. Oral infection in 12 weeks old quail revealed, only 15% of birds were died  during observation period. Diarrhoea and saturation of vent plumage were only noticed clinical signs in 65% of birds. Most of examined birds showed enteritis and increased intestinal contents specially at dudenum, and jejunum, while some birds showed focal hepatic changes. Excreation of C. jejuni started from second day post-infection till the end of observation period. C. jejuni was reisolated from intestinal tract and coloaca in all infected birds, while isolation from oviduct and liver was done from some cases. Stool swab cultures from human resulted in isolation of C. jejuni from 17.9% of examined persons with bowl incontinences and 8.3% from apparently healthy persons dealing with quail either in rearing or in slaughter shops.
