Optimising a 6-plex tetanus-diphtheria-pertussis fluorescent bead-based immunoassay

Small volume assays are required for large-scale research studies and in particular paediatric trials, where multiple measures are required from a single sample. Fluorescent bead-based technology (Bioplex/Luminex) allows high through-put and simultaneous quantification of multiple analytes in a single test. This technology uses sets of microspheres, each with a unique spectral address that can be coated with a different antigen of interest.

Nasal delivery of a commensal Pasteurellaceae species inhibits nontypeable Haemophilus influenzae colonisation and delays onset of otitis media in mice

We have demonstrated that a single dose of a closely related commensal can delay onset of NTHi otitis media in vivo

Researchers may have found key to preventing asthma

Researchers have made a world-first discovery on how to prevent severe respiratory infections in babies.

Combination of clinical symptoms and blood biomarkers can improve discrimination between bacterial or viral community-acquired pneumonia in children

Combining elevated CRP with the presence or absence of clinical signs/ symptoms differentiates definite bacterial from presumed viral pneumonia better than CRP alone

Immunogenicity of pneumococcal vaccine schedules in high-risk infants in Papua New Guinea

Panel 8: Vaccines and immunology

Review and highlight of the significant advances made towards vaccine development and understanding of the immunology of otitis media

High concentrations of middle ear antimicrobial peptides and proteins are associated with detection of middle ear pathogens in children with recurrent acute otitis media

Elevated antimicrobial proteins and peptides and cytokines in middle ear effusion are a marker of inflammation and bacterial persistence

Cord blood Streptococcus pneumoniae-specific cellular immune responses predict early pneumococcal carriage in high-risk infants in Papua New Guinea

We aimed to explore whether newborns in high-risk areas have pre-existing pneumococcal-specific cellular immune responses that effects early acquisition.

Hospitalisation for bronchiolitis in infants is more common after elective caesarean delivery

The authors previously reported an increased risk of hospitalisation for acute lower respiratory infection up to age 2 years in children delivered by...

Lipopolysaccharide-induced interferon response networks at birth are predictive of severe viral lower respiratory infections in the first year of life

Appropriate innate immune function is essential to limit pathogenesis and severity of severe lower respiratory infections (sLRI) during infancy, a leading cause of hospitalization and risk factor for subsequent asthma in this age group.
