Streptococcus pneumoniae Proteins AmiA, AliA, and AliB Bind Peptides Found in Ribosomal Proteins of Other Bacterial Species

Frontiers in Microbiology, 2018
The nasopharynx is frequently colonized by both commensal and pathogenic bacteria including Streptococcus pneumoniae (pneumococcus). Pneumococcus is an important pathogen responsible for bacterial meningitis and community acquired pneumonia but is also ...

Carriage Dynamics of Pneumococcal Serotypes in Naturally Colonized Infants in a Rural African Setting During the First Year of Life

Frontiers in Pediatrics, 2021
Streptococcus pneumoniae (the pneumococcus) carriage precedes invasive disease and influences population-wide strain dynamics, but limited data exist on temporal carriage patterns of serotypes due to the prohibitive costs of longitudinal studies.

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

A low-cost culture- and DNA extraction-free method for the molecular detection of pneumococcal carriage in saliva

Microbiology Spectrum
Molecular methods have improved the sensitivity of the detection of pneumococcal carriage in saliva. However, they typically require sample culture enrichment and nucleic acid extraction prior to performing the detection assay and may limit scalability ...

THE OCCURRENCE OF PEROXIDE IN CULTURES OF PNEUMOCOCCUS

Journal of Experimental Medicine, 1924
1. Conditions which favor the formation and accumulation of peroxide in broth cultures of pneumococcus are free access of air, and the absence of catalase, peroxidase, and other catalysts capable of decomposing this compound.

Engineering Tertiary Lymphoid Structures: Nanomedicine, Bioengineering, and Biomaterials for Precision Immunotherapy

Advanced NanoBiomed Research, EarlyView.
This review explains how biomaterials and nanoparticles can be used to induce or modulate tertiary lymphoid structures (TLSs), which are ectopic immune hubs that form in nonlymphoid tissues during chronic disease and cancer. By comparing different methods, the article highlights design principles for modeling TLSs or recapitulating specific TLS ...

A role of oropharyngeal microbiota in developing acute and chronic diseases of the upper respiratory tract

Инфекция и иммунитет, 2020
Currently, a rise in incidence of polyethological inflammation of the upper respiratory tract mucosa paralleled by altered resident and transient microbiota displaying in many cases increased antibiotic resistance has been noted.
