Evaluation of a LPS-based glycoconjugate vaccine against bovine Escherichia coli mastitis: Formation of LPS Abs in cows after immunization with E. coli core oligosaccharides conjugated to hemocyanine.

Abstract excerpt

The immune response of cows against the core oligosaccharide of Escherichia coli rough mutants (core types R1-R4, K-12 and J-5) was investigated after immunization with a synthetic glycoconjugate composed of deacylated LPS conjugated to hemocyanine (22 animals). Ab formation was measured by ELISA using LPS or deacylated LPS conjugated to BSA as an Ag. The glycoconjugate immunogens were used to vaccinate cows (36...
