Whole genome sequencing of these resistant mutants revealed seven distinct mutations in genes encoding for enzymes involved in O1 antigen biosynthesis, demonstrating that the O1 antigen is a previously uncharacterized putative receptor of ICP3. To further elucidate the specificity of the resistance conferred by these mutations, they were challenged with the\n                  <jats:italic>V. cholerae<\/jats:italic>\n                  -specific phages ICP1 and ICP2. All seven O1 antigen mutants demonstrated pan-resistance to ICP1 but not ICP2, which utilizes the OmpU outer membrane protein as a receptor.
