-
construction of pglH::kanr mutants, and complementation studies. The pglH::kanr mutant of strain 81116 has reduced colonization efficiency in a chick model. Mutation of pglH in strains 11168H and 81116 results in the reduced attachment to and invasion of Caco-2 cells. Reduction in attachment and invasion for strain 81116 are 23fold and 15fold, respectively, whereas the corresponding figures for strain 11168H are 6fold and and 5.4fold, respectively

replacement of the strain N400 locus carrying the deleted form of ORFs 2 and 3 with those derived from the Neisseria gonorrhoeae strain FA1090 and from diverse neisserial strains into Neisseria gonorrhoeae strain N400 in which the pgl gene function and associated glycan structures is defined, mutant glycosylation patterns, overview. The presence of a stereotypic, conserved deletion mutation is inactivating pglH in strains of Neisseria gonorrhoeae, Neisseria meningitidis, and related commensals
