Variants of Streptococcus pneumoniae Serotype 14 from Papua New Guinea with the Potential to Be Mistyped and Escape Vaccine-Induced Protection

Streptococcus pneumoniae (the pneumococcus) is a human pathogen of global importance, classified into serotypes based on the type of capsular polysaccharide produced. Serotyping of pneumococci is essential for disease surveillance and vaccine impact measurement.

Reduced rhinovirus-specific antibodies are associated with acute exacerbations of chronic obstructive

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are often linked to respiratory infections.

Securing the supply of benzathine penicillin: a global perspective on risks and mitigation strategies to prevent future shortages

Benzathine benzylpenicillin is a globally indispensable medicine.

Effect of early carriage of streptococcus pneumoniae on the development of pneumococcal protein-specific cellular immune responses in infancy

The aim of this study was to examine the relationship between nasopharyngeal pneumococcal colonization in early life and the development of T cell responses.

IgG Responses to Pneumococcal and Haemophilus Influenzae Protein Antigens Are Not Impaired in Children with a History of Recurrent Acute Otitis Media

Vaccines including conserved antigens from Streptococcus pneumoniae & nontypeable Haemophilus influenzae have the potential to reduce of otitis media.

Searching for Strep A in the clinical environment during a human challenge trial: a sub-study protocol

Streptococcus pyogenes (also known as group A Streptococcus , Strep A) is an obligate human pathogen with significant global morbidity and mortality. Transmission is believed to occur primarily between individuals via respiratory droplets, but knowledge about other potential sources of transmission via aerosols or the environment is limited. Such knowledge is required to design optimal interventions to control transmission, particularly in endemic settings.

State transitions across the Strep A disease spectrum: scoping review and evidence gaps

The spectrum of diseases caused by Streptococcus pyogenes (Strep A) ranges from superficial to serious life-threatening invasive infections. We conducted a scoping review of published articles between 1980 and 2021 to synthesize evidence of state transitions across the Strep A disease spectrum. We identified 175 articles reporting 262 distinct observations of Strep A disease state transitions.

Immunotherapy of allergic diseases by bacterial products

Allergic diseases are characterized by excessive immunoglobulin E (IgE) production, mast cell degranulation, tissue eosinophilia and mucus hypersecretion

Two newly identified cat allergens: The von Ebner gland protein Fel d 7 and the latherin-like protein Fel d 8

Characterization of the complete IgE binding spectrum of cat allergens is important for the development of improved diagnosis and effective immunotherapeutics.

The advent of recombinant allergens and allergen cloning Authors:

When the allergen nomenclature system was adopted in 1986, allergens were identified by their behavior on electrophoresis and chromatography...

The anti-inflammatory effects of interleukin-4 are not mediated by suppressor of cytokine signalling-1 (SOCS1)

While it is known that the anti-inflammatory effects of interleukin (IL)-4 require new protein synthesis, the exact mechanisms by which IL-4 suppresses the prod

Increased allergic immune response to Sarcoptes scabiei antigens in crusted versus ordinary scabies

Scabies, a parasitic skin infestation by the burrowing "itch" mite Sarcoptes scabiei, causes significant health problems for children and adults worldwide.

Th2-associated immunity to bacteria in asthma in teenagers and susceptibility to asthma

Bacterial colonisation of the airways is associated with increased risk of childhood asthma

The Western Environment Reduces Innate Immune Cytokine Production in Chinese Immigrants

We recruited age- and sex-matched Chinese immigrants living in Western Australia for less than 6 months (newly arrived, n = 22) or more than 5 years.
