Stability of influenza A virus in droplets and aerosols is heightened by the presence of commensal respiratory bacteria
Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Walter Hugentobler, Htet Kyi Wynn, Céline Terrettaz, Aline Laetitia Schaub, Shannon Christa David, Laura José Costa Henriques, Daniel Scott Nolan, Marta Augugliaro
Aerosol transmission remains a major challenge for control of respiratory viruses, particularly those causing recurrent epidemics, like influenza A virus (IAV). These viruses are rarely expelled alone, but instead are embedded in a consortium of microorgan ...
2024Using Negative Control Populations to Assess Unmeasured Confounding and Direct Effects
Sometimes treatment effects are absent in a subgroup of the population. For example, penicillin has no effect on severe symptoms in individuals infected by resistant Staphylococcus aureus, and codeine has no effect on pain in individuals with certain polym ...
Lippincott Williams & Wilkins2024Microfluidic systems for infectious disease diagnostics
Microorganisms, encompassing both uni- and multicellular entities, exhibit remarkable diversity as omnipresent life forms in nature. They play a pivotal role by supplying essential components for sustaining biological processes across diverse ecosystems, i ...
Cambridge2024Dangerous acquaintances: the interplay between type IV pili and the type VI secretion system during Vibrio cholerae's environmental lifestyle
Cholera, caused by the bacterium Vibrio cholerae, has affected humanity throughout history and still impacts millions of people every year. Apart from being a human pathogen, V. cholerae is a common member of the aquatic environment. Due to this natural re ...
EPFL2024Alpha1-antitrypsin improves survival in murine abdominal sepsis model by decreasing inflammation and sequestration of free heme
Background Excessive inflammation, hemolysis, and accumulation of labile heme play an essential role in the pathophysiology of multi-organ dysfunction syndrome (MODS) in sepsis. Alpha1-antitrypsin (AAT), an acute phase protein with heme binding capacity, i ...
Frontiers Media Sa2024Vibrio cholerae pathogenicity island 2 encodes two distinct types of restriction systems
Melanie Blokesch, David William Adams, Alexandre Lemopoulos, Grazia Vizzarro
In response to predation by bacteriophages and invasion by other mobile genetic elements such as plasmids, bacteria have evolved specialised defence systems that are often clustered together on genomic islands. The O1 El Tor strains of Vibrio cholerae resp ...
2024Interactions between pili affect the outcome of bacterial competition driven by the type VI secretion system
Melanie Blokesch, Anne-Florence Raphaëlle Bitbol, Alexandre Lemopoulos, Simon Bernhard Otto, Richard Marie Servajean
The bacterial type VI secretion system (T6SS) is a widespread, kin-discriminatory weapon capable of shaping microbial communities. Due to the system’s dependency on contact, cellular interactions can lead to either competition or kin protection. Cell-to-ce ...
