<i>Haemophilus influenzae</i> Outer Membrane Protein P6 Molecular Characterization May Not Differentiate All Strains of <i>H. Influenzae</i> from <i>H. haemolyticus</i>

Abstract

Distinguishing nontypeable Haemophilus influenzae and Haemophilus haemolyticus isolates by outer membrane protein (OMP) P6 gene sequencing is complicated by sequence variants in isolates. Further testing using RapID NH and multilocus sequence analysis may not help identify some isolates. Translated OMP P6 gene sequences are not conserved among all isolates presumed to be H. influenzae.
