Abstract

ne handred and twenty ducks, 1 to 32 weeks old, suffering from symptoms of diarrhea were collected from different farms at Sharkia province representing 20 flocks, were subjected to clinical and postmortem examination. Bacterial isolation were carries out on examined birds. The study revealed that six bacterial isolates of C. jejuni were isolated. The isolates were morphologically and biochemically idendified. The incidence of compylobater infection in ducks was 5%. Campylobacter jejuni six isolates were biotyped as biotype 1 (5), and biotype Ia (1) isolates.
The experimental infection with bacterial isolates on 30 days old ducks was carried out. The morbidity and mortality were 80% and 10%. Respectively.
The histopathological studies in the affected organs of infected ducks were reported. All campylobacter jejuni isolates were found highly sensitive to gentamycin, flumequine, oxytetracycline and trimethoprim.
