Abstract
Antigens were heat extracted from Campylobacter jejuni (LI04) and C co li (LI020) in the presence of ethylenediaminetetraacetate (EDTA) and w ere recovered in the supernatant of a low-speed centrifugation. The me thod is simpler, safer and more efficient in extracting lipopolysaccha ride (LPS) antigens than the hot phenol method. The extracted antigens (LPS plus several proteins) elicited production of antigen-specific a ntibodies in the egg yolk of immunized hens. Antibodies purified by po lyethyleneglycol fractionation were used to detect antigens fractionat ed on SDS polyacrylamide gel electrophoresis.
