Prevalence and subtyping of biofilms present in bronchoalveolar lavage from children with protracted bacterial bronchitis or non-cystic fibrosis bronchiectasis: a cross-sectional studyLower airway biofilms are hypothesised to contribute to poor treatment outcomes among children with chronic lung disease; however, data are scarce.

Australian Aboriginal Otitis-Prone Children Produce High-Quality Serum IgG to Putative Nontypeable Haemophilus influenzae Vaccine Antigens at Lower Titres Compared to Non-Aboriginal ChildrenNontypeable Haemophilus influenzae (NTHi) is the most common bacterial otopathogen associated with otitis media (OM). NTHi persists in biofilms within the middle ears of children with chronic and recurrent OM. Australian Aboriginal children suffer exceptionally high rates of chronic and recurrent OM compared to non-Aboriginal children.

Meningococcal B vaccine and meningococcal carriage in adolescents in AustraliaAmong Australian adolescents, the 4CMenB vaccine had no discernible effect on the carriage of disease-causing meningococci, including group B

Preparing for Life: Plasma Proteome Changes and Immune System Development During the First Week of Human LifeNeonates have heightened susceptibility to infections. The biological mechanisms are incompletely understood but thought to be related to age-specific adaptations in immunity due to resource constraints during immune system development and growth. We present here an extended analysis of our proteomics study of peripheral blood-plasma from a study of healthy full-term newborns delivered vaginally, collected at the day of birth and on day of life (DOL) 1, 3, or 7, to cover the first week of life. The plasma proteome was characterized by LC-MS using our established 96-well plate format plasma proteomics platform.

Developmental outcomes following vaccine-proximate febrile seizures in childrenTo compare the developmental and behavioral outcomes of children experiencing an initial vaccine-proximate (VP) febrile seizure (FS) to those having a non-VP-FS (NVP-FS) and controls who have not had a seizure.

The reliability of video otoscopy recordings and still images in the asynchronous diagnosis of middle-ear diseaseTo compare the asynchronous assessment of video otoscopic still images to recordings by an audiologist and ear, nose and throat surgeon (ENT) for diagnostic reliability and agreement in identifying middle-ear disease.

4CMenB Breadth of Immune Response, Immunogenicity, and Safety: Results from a Phase 3 Randomized, Controlled, Observer Blind Study in Adolescents and Young AdultsMeningococcal serogroup B (MenB) strains are highly diverse. Breadth of immune response for the MenB vaccine, 4CMenB, administered at 0-2, 0-6, or 0-2-6 months, was demonstrated by endogenous complement-human serum bactericidal antibody (enc-hSBA) assay against an epidemiologically relevant panel of 110 MenB strains.

A PCR-high-resolution melt assay for rapid differentiation of nontypeable Haemophilus influenzae and Haemophilus haemolyticusWe have developed a PCR-high-resolution melt (PCR-HRM) assay to discriminate nontypeable Haemophilus influenzae (NTHi) colonies from Haemophilus haemolyticus

Assessing the protective effect of influenza vaccine against laboratory confirmed influenza in hospitalised children aged 6-59 monthsInfluenza vaccine was offered to all children aged 6-59 months resident in Western Australia in 2008, and we wished to evaluate the effectiveness of this immunisation programme.

Detection of the rapid emergency of the H274 mutation associated with oseltamivir-resistanceIn 2009 a new swine-origin influenza virus A/H1N1 (A/H1N1 09) emerged, causing the century's first pandemic.
