Poultry plays an important role in our national income which fulfill our needs from animal protein. Avian Borreliosis is considered a serious diseases and immunology causes high losses among affected birds and because Borrelia anserina has no similar antiThe study was planned to spotlight on:1. Microscopic examination of blood samples from ducks and geese2. Isolation, attempts to cultivate and preserve Borrelia anserina.3. Determination of antigenicity of Borrelia anserina isolates.4. RAPD -PCR technique to compare these isolates.5. Trials to prepare polyvalent vaccine from various isolates to control Borreliosis in ducks and geese.The obtained results could be summarized as follows:I.Eight isolates of Borrelia anserina were secured from sixteen localities distributed allover Sharkia Governorate.
