In: Zagazig Veterinary Journal 2010.v.38(2)Summary: A field trails was conducted to evaluate the immunogenicity of an inactivated Escherichia coli vaccine composed of serotypes 0 1, 02 and 0 78 . Two Hubbard broiler chick flocks (1000 each) were used through the experimental work of this study. In trial Nol, chickens were vaccinated twice at 10 and 20 days of age, while those in trial N02 were vaccinated once at 10 days of age. Another 100 chickens of same age were served as controls . Humoral immune responses as assessedd by Enzyme Immuno Sorbant Assay (ELISA) documented an increase in serotype -specific antibodies IGy in vaccinated birds in the two trials. Mortality and gross lesions scores of both vaccinated flocks were compared with those of unvaccinated flocks, on the other hand chicken in trial Nol had significantly lower mortality and lower score lesions than those in flock N02 indicating that two doses of vaccine gave long -last immunity than one dose.
