Community‐Acquired Moraxella catarrhalis Bacteremic Pneumonia: Two Case Reports and Review of the Literature

Case Reports in Pulmonology, Volume 2016, Issue 1, 2016., 2016
Moraxella (formerly Branhamella) catarrhalis was discovered at the end of the nineteenth century, and for many decades it was considered to be a harmless commensal of the upper respiratory tract. It is a Gram‐negative, aerobic diplococcus considered to be the third most common pathogen isolated in childhood sinusitis and otitis media and in adult ...

The Lung Immune Response to Nontypeable Haemophilus influenzae (Lung Immunity to NTHi)

Journal of Immunology Research, Volume 2015, Issue 1, 2015., 2015
Haemophilus influenzae is divided into typeable or nontypeable strains based on the presence or absence of a polysaccharide capsule. The typeable strains (such as type b) are an important cause of systemic infection, whilst the nontypeable strains (designated as NTHi) are predominantly respiratory mucosal pathogens.

Mutant ftsI genes in the emergence of penicillin-binding proteinmediated β-lactam resistance in Haemophilus influenzae in Norway [PDF]

, 2010
The most important mechanism for β-lactam resistance in β-lactamase-negative ampicillin-resistant (BLNAR) isolates of Haemophilus influenzae is the alteration of penicillin-binding protein 3 (PBP3) as a result of ftsI gene mutations.

Antimicrobial Resistance Trends among Community‐Acquired Respiratory Tract Pathogens in Greece, 2009–2012

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
The aim of the present study was to determine the antimicrobial resistance trends of respiratory tract pathogens isolated from patients with community‐acquired respiratory tract infections (CARTIs) in Crete, Greece, over a 4‐year period (2009–2012).

, 2009
Objectives: The aim was to study the pharmacodynamics of cefditoren, amoxicillin/clavulanic acid and cefuroxime against mixed Haemophilus influenzae strains.

Antimicrobial resistance patterns of Haemophilus influenzae isolated from patients with meningitis in São Paulo, Brazil

Brazilian Journal of Medical and Biological Research, 2000
From 1989 to 1995, a total of 391 Haemophilus influenzae isolates were recovered from the cerebrospinal fluid (CSF) of hospitalized patients in São Paulo, Brazil. The majority of strains were isolated from infants aged less than 5 years.

Evidence of Bacterial Biofilms among Infected and Hypertrophied Tonsils in Correlation with the Microbiology, Histopathology, and Clinical Symptoms of Tonsillar Diseases

International Journal of Otolaryngology, Volume 2013, Issue 1, 2013., 2013
Diseases of the tonsils are becoming more resistant to antibiotics due to the persistence of bacteria through the formation of biofilms. Therefore, understanding the microbiology and pathophysiology of such diseases represent an important step in the management of biofilm‐related infections.

In vitro activity of telithromycin against Haemophilus influenzae at epithelial lining fluid concentrations

BMC Microbiology, 2008
Background Haemophilus influenzae is one of the main aetiological agents of community-acquired respiratory tract infections. The primary aim of this study was to evaluate the antibacterial activity of telithromycin against H. influenzae clinical isolates

Haemophilus influenzae and the lung (Haemophilus and the lung)

Clinical and Translational Medicine, Volume 1, Issue 1, December 2012., 2012
Abstract Haemophilus influenzae is present as a commensal organism in the nasopharynx of most healthy adults from where it can spread to cause both systemic and respiratory tract infection. This bacterium is divided into typeable forms (such as type b) or nontypeable forms based on the presence or absence of a tough polysaccharide capsule.

Ampicillin-resistant non-beta-lactamase-producing Haemophilus influenzae in Spain:recent emergence of clonal isolates with increased resistance to cefotaxime and cefixime [PDF]

, 2007
The sequence of the ftsI gene encoding the transpeptidase domain of penicillin-binding protein 3 (PBP 3) was determined for 354 nonconsecutive Haemophilus influenzae isolates from Spain; 17.8% of them were ampicillin susceptible, 56% were beta-lactamase ...
