Bacteriophage F336 recognizes the capsular phosphoramidate modification of Campylobacter jejuni NCTC11168.

ABSTRACT: Bacteriophages infecting the food-borne human pathogen Campylobacter jejuni could potentially be exploited to reduce bacterial counts in poultry prior to slaughter. This bacterium colonizes the intestinal tract of poultry in high numbers, and contaminated poultry meat is regarded as the major source of human campylobacteriosis. In this study, we used phage F336 belonging to the Myoviridae family to select a C. jejuni NCTC11168 phage-resistant strain, called 11168R, with the aim of investigating the mechanisms of phage resistance. We found that phage F336 has reduced adsorption to 11168R, thus indicating that the receptor is altered. While proteinase K-treated C. jejuni cells did not affect adsorption, periodate treatment resulted in reduced adsorption, suggesting that the phage binds to a
