Estimating the term…
The present invention relates to vaccines comprising antiserum raised against a flagellaless Campylobacter strain for the prevention of Campylobacter colonisation in animals. The invention also relates to antigenic Campylobacter proteins visible in a Western blot of Campylobacter jejuni protein after incubation of said Western blot with antibodies against a flagellaless mutant of Campylobacter jejuni and not visible after incubation of said blot with antibodies against wild type Campylobacter jejuni, and to their use in vaccines and the manufacturing thereof. The invention further relates to vaccines comprising such proteins and antibodies against such proteins. The invention further relates to the use of such Campylobacter proteins and to antiserum and antibodies raised against Campylobacter antigens for the preparation of vaccines. Finally, the invention relates to methods for the preparation of such vaccines.
A vaccine for the prevention of Campylobacter colonization in animals consisting essentially of an effective amount of chicken antiserum raised against a flagellaless Campylobacter strain wherein the antiserum recognizes a 97 kD (+/−5 kD), a 60 kD (+/−5 kD), and a 13 kD (+/−3 kD) band on a Western Blot, the vaccine essentially free of anti-flagellar antibodies.
A vaccine for the prevention of Campylobacter jejuni colonization in poultry comprising an effective amount of chicken antibodies against the antigenic protein consisting essentially of a protein of a Campylobacter having a molecular weight of 97 kD (+/−5kD), whereby it is visible in a Western blot with antibodies against a flagellaless mutant of Campylobacter jejuni and that it is not visible after incubation of said blot with antibodies against the wild type Campylobacter jejuni, the vaccine essentially free of anti-flagellar antibodies.
