Inflammation induced by influenza virus impairs human innate immune control of pneumococcus [PDF]

, 2018
Colonization of the upper respiratory tract by pneumococcus is important both as a determinant of disease and for transmission into the population. The immunological mechanisms that contain pneumococcus during colonization are well studied in mice but ...

PNEUMOCOCCUS HEMOTOXIN [PDF]

Journal of Experimental Medicine, 1914
Solutions of the bodies of pneumococci, obtained by dissolving them in dilute solutions of sodium cholate, by permitting them to undergo autolysis, or by first freezing, drying, and then grinding in salt solution, are actively hemolytic for rabbit, sheep, guinea pig, and human red blood corpuscles. The substance on which this hemolytic property depends

PM2.5 impairs macrophage functions to exacerbate pneumococcus-induced pulmonary pathogenesis

Particle and Fibre Toxicology, 2020
Background Pneumococcus is one of the most common human airway pathogens that causes life-threatening infections. Ambient fine particulate matter (PM) with aerodynamic diameter ≤ 2.5 μm (PM2.5) is known to significantly contribute to respiratory diseases.

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

Southern 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

A STUDY OF PNEUMOCOCCUS AUTOLYSIS [PDF]

Journal of Experimental Medicine, 1929
1. Autolysis of Pneumococcus is accompanied by proteolysis, which results in an increase in amino and non-coagulable nitrogen. 2. Autolysis of Pneumococcus is accompanied by lipolysis during which there is a liberation of ether-soluble fatty acids. 3.
