Systematic review and meta-analysis on the etiology of bacterial pneumonia in children in sub-Saharan Africa

open access: yesJournal of Public Health in Africa, 2022
Introduction. Before the introduction of vaccination to protect children from pneumonia, Streptococcus pneumoniae and Haemophilus influenzae type B (HiB) were the most frequent aetiological agents causing bacterial pneumonia in children under five years ...

SEROLOGICAL REACTIONS IN PNEUMONIA WITH A NON-PROTEIN SOMATIC FRACTION OF PNEUMOCOCCUS

open access: yesJournal of Experimental Medicine, 1930
1. Sera from individuals acutely ill with lobar pneumonia possess the capacity to precipitate in high titre a non-protein somatic fraction derived from pneumococci (Fraction C). Following crisis the reaction is no longer demonstrable. 2.

Overlapping functionality of the Pht proteins in zinc homeostasis of streptococcus pneumoniae [PDF]

open access: yes, 2014
Streptococcus pneumoniae is a globally significant pathogen that causes a range of diseases, including pneumonia, sepsis, meningitis, and otitis media. Its ability to cause disease depends upon the acquisition of nutrients from its environment, including

Pneumococcal Polysaccharide Conjugated Vaccines and the Problem of Changing Circulating Serotypes of Pneumococcus

open access: yesЭпидемиология и вакцинопрофилактика, 2023
Relevance. In 2007, WHO recommended pneumococcal conjugate vaccines (PCV) be included in national immunization schedules for young children. By 2020, 145 countries, including Russia, were using PCV. Aims.

Pneumococcus nasopharyngeal carriage in children attending an academic hospital in Pretoria, South Africa, after the introduction of pneumococcal vaccine

open access: yesSouthern African Journal of Infectious Diseases, 2019
Background: In 2009, pneumococcal conjugate vaccine was introduced in South Africa. However, there are concerns that this could lead to an increase in colonisation of non-vaccine serotypes (serotype replacement). Methods: In a cross-sectional study, 350

Vaccination as a solution of the issue of resistance S. pneumoniae

open access: yesЭпидемиология и вакцинопрофилактика, 2021
Relevance Antimicrobial resistance (AMR) is a growing acute global health issue. Uncontrolled combined use of antibiotics determines changes in the microbial agents' properties, leading to a decrease of susceptibility to antimicrobial substances and ...

Naturally Acquired Human Immunity to Pneumococcus Is Dependent on Antibody to Protein Antigens

open access: yesPLoS Pathogens, 2017
Naturally acquired immunity against invasive pneumococcal disease (IPD) is thought to be dependent on anti-capsular antibody. However nasopharyngeal colonisation by Streptococcus pneumoniae also induces antibody to protein antigens that could be ...
