  • Antisera against a PEB1 antigen from Campylobacter jejuni
    Patent number: 5470958
    Abstract: An antigenic composition includes antigens obtainable from Campylobacter jejuni and may be used as a vaccine to induce protective antibodies against both Campylobacter coli and Campylobacter jejuni. The antigenic composition, and antisera specific to the antigens can be used to detect Campylobacter coli or Campylobacter jejuni infection. Diagnostic detection kits include the novel antigenic composition or antisera thereto.

  • Diagnostic testing for Campylobacter jejuni or Campylobacter coli infections using novel antigens
    Patent number: 5200344
    Abstract: Antigenic compositions useful in diagnostic testing for the presence of Campylobacter jejuni or Campylobacter coli comprising a PEB1 antigen obtained from Campylobacter jejuni having an apparent molecular weight of about 28 kDa as measured by SDS-PAGE under reducing conditions, a molecular weight of 28.9 .+-.1.0 kDa as measured by gel filtration chromatography under native conditions and an isoelectric point of 8.5 or a PEB3 antigen obtained from Campylobacter jejuni having an apparent molecular weight of about 30 kDa as measured by SDS-PAGE under reducing conditions and an isoelectric point of greater than 9.3 or a combination thereof.
