The commensal Haemophilus haemolyticus is difficult to differentiate from the respiratory pathogen Haemophilus influenzae using phenotypic tests. In a study that used molecular tests to retrospectively identify 447 phenotypically identified H. influenzae isolates from diagnostic specimens in Australia, only 7 (1.5%) H. haemolyticus were identified.
