Non-typeable Haemophilus influenzae (NTHi), a common commensal of the human pharynx, is also an opportunistic pathogen if it becomes established in the lower respiratory tract (LRT). In comparison to colonizing isolates from the upper airway, LRT isolates, especially those associated with exacerbations of chronic obstructive pulmonary disease, have increased resistance to the complement- and an...

To obtain more information on the much-debated definition of prokaryotic species, we investigated the borders of Haemophilus influenzae by comparative analysis of H. influenzae reference strains with closely related bacteria including strains assigned to Haemophilus haemolyticus, cryptic genospecies biotype IV, and the never formally validated species "Haemophilus intermedius". Multilocus seque...

Background: Acute otitis media (AOM) is one of the most common childhood diseases requiring antimicrobial prescription drugs in pre-school children. In this study, we sought to describe the bacterial etiology of pediatric cases of AOM in Turkey. Materials and Methods: This prospective, multi-center, tympanocentesis-based epidemiological study was performed during 2010-2012in children aged betwe...

We present a case of Haemophilus influenzae lobar pneumonia in the father of a child admitted with acute epiglottitis caused by the same organism. The suggestion that adult, as well as child, contacts for Haemophilus influenzae epiglottitis should be prophylactically treated is discussed.

Little attention has been paid to the degradation of nucleotides by the genus Haemophilus although Lwoff and Lwoff (1937a, b) and McIlwain and Hughes (1948) demonstrated that Haemophilus parainfluenzae was capable of destroying diphosphopyridine nucleotide (DPN). More recently, Kalckar (1954) reported the occurrence of a specific nucleotide pyrophosphatase and associated nucleotide phosphatase ...
