Inoculation of chicks with viable non-colonizing strains of Campylobacter jejuni: Evaluation of protection against a colonizing strain

Abstract

We have treated chicks with viable non-colonizing mutant strains of Campylobacter jejuni to test these as a possible vaccine. We found that intramuscular inoculation with and without adjuvant, and with or without a concomitant oral dose of non-colonizing strains, failed to provoke protective immunity.
