A PCR for protein D (hpd#3) was used to differentiate nontypeable Haemophilus influenzae (NTHI) from Haemophilus haemolyticus. While 90% of nasopharyngeal specimens and 100% of lower-airway specimens from 84 Indigenous Australian children with bronchiectasis had phenotypic NTHI isolates confirmed as H. influenzae, only 39% of oropharyngeal specimens with phenotypic NTHI had H. influenzae. The n...

We present two cases of non-capsulated Haemophilus influenzae hepatobiliary infection and review the literature. Such cases are rare, and prior to routine immunization against H. influenzae serotype b invasive Haemophilus disease was largely caused by capsulated strains. The epidemiology of invasive Haemophilus infections has changed and the number of cases of intra-abdominal and hepatobiliary ...

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...

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 ...

A total of 100 and 97% of Haemophilus influenzae type b strains from major infections were susceptible, respectively, to levels of rifampin and sulfisoxazole attainable in saliva. It is theoretically feasible to eliminate Haemophilus influenzae from the nasopharynx with these drugs.
