title: Detection of cryptic genospecies misidentified as Haemophilus influenzae in routine clinical samples by assessment of marker genes fucK, hap, and sodC.
abstract: Clinical isolates of Haemophilus influenzae were assessed for the presence of fucK, hap, and sodC by hybridization with gene-specific probes, and isolates diverging from the expected H. influenzae genotype were characterized by phenotype and 16S rRNA gene sequencing. Two of 480 isolates were finally classified as variant strains ("nonhemolytic Haemophilus haemolyticus").
