Article Reference Oropharyngeal colonization by nontypeable Haemophilus influenzae among healthy children attending day care centers.
Haemophilus influenzae colonizes the upper respiratory tract and can spread causing otitis and sinusitis. This work aimed to study the oropharyngeal carriage ...
Article Reference Prevalence and genetic diversity of nontypeable haemophilus influenzae in the respiratory tract of infants and primary caregivers.
Nontypeable Haemophilus influenzae (NTHi) causes otitis media, sinusitis, and likely lower respiratory tract infections in children. Colonization, strain ...
Article Reference A clonal group of nontypeable Haemophilus influenzae with two IgA proteases is adapted to infection in chronic obstructive pulmonary disease.
Strains of nontypeable Haemophilus influenzae show enormous genetic heterogeneity and display differential virulence potential in different clinical settings. ...
Article Reference Molecular basis of increased serum resistance among pulmonary isolates of non-typeable Haemophilus influenzae.
Non-typeable Haemophilus influenzae (NTHi), a common commensal of the human pharynx, is also an opportunistic pathogen if it becomes established in the lower ...
Article Reference Haemophilus influenzae outer membrane protein P6 molecular characterization may not differentiate all strains of H. Influenzae from H. haemolyticus.
Distinguishing nontypeable Haemophilus influenzae and Haemophilus haemolyticus isolates by outer membrane protein (OMP) P6 gene sequencing is complicated by ...
Article Reference Variation in expression of HMW1 and HMW2 adhesins in invasive nontypeable Haemophilus influenzae isolates.
Among surface antigens of nontypeable Haemophilus influenzae (NTHi), the HMW1 and HMW2 proteins are the major adhesins promoting colonization of the upper ...
Article Reference Genetic diversity of paired middle-ear and pharyngeal nontypeable Haemophilus influenzae isolates from children with acute otitis media.
Pulsed-field gel electrophoresis was used to determine genetic diversities of multiple nontypeable Haemophilus influenzae isolates from throat and ear ...
Article Reference [Study on genetic diversity of genes encoding main adhesins among nontypeable Haemophilus influenzae strains isolated from children in Poland].
The study was based on hypothesis that in the nontypeable population of H. influenzae strains isolated from children there are some genetically predisposed to ...
Article Reference Conservation and diversity of HMW1 and HMW2 adhesin binding domains among invasive nontypeable Haemophilus influenzae isolates.
The pathogenesis of nontypeable Haemophilus influenzae (NTHi) begins with adhesion to the rhinopharyngeal mucosa. In almost 80% of NTHi clinical isolates, the ...
Article Reference High rates of recombination in otitis media isolates of non-typeable Haemophilus influenzae.
Non-typeable (NT) or capsule-deficient, Haemophilus influenzae (Hi) is a common commensal of the upper respiratory tract of humans and can be pathogenic ...
Article Reference Sequence stability of the gene encoding outer membrane protein P2 of nontypeable Haemophilus influenzae in the human respiratory tract.
Nontypeable Haemophilus influenzae (NTHI) is an important cause of lower respiratory tract infections in patients with chronic obstructive pulmonary disease. ...
Article Reference Use of pulsed-field gel electrophoresis, enterobacterial repetitive intergenic consensus typing, and automated ribotyping to assess genomic variability among strains of nontypeable Haemophilus influenzae.
We compared 75 nontypeable (NT) Haemophilus influenzae isolates by pulsed-field gel electrophoresis (PFGE), enterobacterial repetitive intergenic consensus ...
Article Reference Secondary structure and molecular analysis of interstrain variability in the P5 outer-membrane protein of non-typable Haemophilus influenzae isolated from diverse anatomical sites.
The sequence of the non-typable Haemophilus influenzae (NTHi) P5 outer-membrane protein from a range of clinical isolates is presented and represents the first ...
