Comparison of laboratory-based and phylogenetic methods to distinguish between Haemophilus influenzae and H. haemolyticus

New methods to distinguish between nontypeable Haemophilus influenzae and nonhemolytic H. haemolyticus were compared. The results of iga variable region hybridization to dotblots and library-on-a-slide microarrays were more similar to a gold standard multigenephylogenetic tree than iga-conserved region hybridization or P6 7F3 epitope immunoblots.
