Long-term derangement of antigen presenting cell populations in the respiratory tract following Influenza A infection

This project investigates how different populations of cells within the respiratory tract immune system are altered during a viral infection.

How immunity shapes the long-term dynamics of influenza H3N2

Since its emergence in 1968, influenza A H3N2 has caused yearly epidemics in temperate regions. While infection confers immunity against antigenically similar strains, new antigenically distinct strains that evade existing immunity regularly emerge ('antigenic drift'). Immunity at the individual level is complex, depending on an individual's lifetime infection history.

Haemophilus influenzae remains the predominant otitis media pathogen in Australian children undergoing ventilation tube insertion in the PCV13 era

Understanding patterns of bacterial carriage and otitis media (OM) microbiology is crucial for assessing vaccine impact and informing policy. The microbiology of OM can vary with geography, time, and interventions like pneumococcal conjugate vaccines (PCVs). We evaluated the microbiology of nasopharyngeal and middle ear effusions in children living in Western Australia, 11 years following the introduction of PCV13.

Widening the lens for pandemic preparedness: children must be seen and heard

The Australian and New Zealand Paediatric Infectious Diseases (ANZPID) Group of the Australasian Society for Infectious Diseases (ASID) calls for urgent consideration of the needs and voices of children in response to the COVID-19 pandemic, and in planning for future pandemics.

How Accurate Are International Classification of Diseases-10 Diagnosis Codes in Detecting Influenza and Pertussis Hospitalizations in Children?

Influenza diagnosis codes had high specificity (98.6%) and modest positive predictive value (PPV; 84.1%) and sensitivity (86.1%) for a laboratory-confirmed...

Protective anti-outer membrane protein immunity against Pasteurella pneumotropica infection of mice

The proteins examined were the homologues of the P4, P6, P26, and D15 proteins of Haemophilus influenzae.

Acute diesel exhaust particle exposure increases viral titre and inflammation associated with existing influenza

Exposure to diesel exhaust particles (DEP) is thought to exacerbate many pre-existing respiratory diseases.

Virus detection and its association with symptoms during influenza-like illness in a sample of healthy adults enrolled in a randomised controlled vaccine trial

Viral respiratory infections are associated with significant morbidity and mortality.

Impacts on influenza A(H1N1)pdm09 infection from cross-protection of seasonal trivalent influenza vaccines and A(H1N1)pdm09 vaccines: Systematic review and meta-analyses

We did a systematic literature search to identify observational and/or interventional studies reporting cross-protection of TIV and A(H1N1)pdm09...

Prospective longitudinal study of respiratory syncytial virus and other respiratory viruses in children <5 years in community settings in metropolitan western Australia: the PATROL study

Respiratory syncytial virus (RSV) is a significant cause of respiratory infections in young children. Since 2021, RSV has been a notifiable disease in Australia. However, current surveillance systems focus on hospitalised RSV, with limited surveillance at a community level through primary care clinics. This approach only captures RSV requiring hospitalisation. Less severe illnesses, while not captured, may have significant social and economic impacts including the associated cost of care and absenteeism. The aim of this study is to establish an understanding of the broader burden of RSV in young children in a community setting.
