Signatures of COVID-19 Severity and Immune Response in the Respiratory Tract Microbiome

open access: yesmedRxiv, 2021
COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection of the respiratory tract, results in highly variable outcomes ranging from minimal illness to death, but the reasons for this are not well understood.

Persistence of High Levels of Serum Complement C5a in Severe COVID-19 Cases After Hospital Discharge

open access: yesFrontiers in Immunology, 2021
Evidence supports a role of complement anaphylatoxin C5a in the pathophysiology of COVID-19. However, information about the evolution and impact of C5a levels after hospital discharge is lacking. We analyzed the association between circulating C5a levels

The Diagnostic Value of Metagenomic Next–Generation Sequencing in Lower Respiratory Tract Infection

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Lower respiratory tract infections are associated with high morbidity and mortality and significant clinical harm. Due to the limited ability of traditional pathogen detection methods, anti-infective therapy is mostly empirical.

An alphaherpesvirus exploits antimicrobial beta-defensins to initiate respiratory tract infection [PDF]

open access: yes, 2020
beta-Defensins protect the respiratory tract against the myriad of microbial pathogens entering the airways with each breath. However, this potentially hostile environment is known to serve as a portal of entry for herpesviruses.
