Inactivation of influenza A virus in expiratory droplets and aerosol particles and the associated physicochemical drivers
Influenza is an infectious respiratory illness caused by influenza viruses. Every year, it causes up to one billion cases of disease worldwide. Despite its high disease burden, the transmission pathway of influenza remains subject to debate. There is incre ...
EPFL2024Human alveolar lining fl uid from the elderly promotes Mycobacterium tuberculosis intracellular growth and translocation into the cytosol of alveolar epithelial cells
Vivek Vijay Thacker, Richa Mishra
The elderly population is highly susceptible to developing respiratory diseases, including tuberculosis, a devastating disease caused by the airborne pathogen Mycobacterium tuberculosis ( M.tb ) that kills one person every 18 seconds. Once M.tb reaches the ...
Elsevier Science Inc2024Effect of Matrix Composition and Thermodynamic Properties on Virus Persistence in Respiratory Droplets
Athanasios Nenes, Tamar Kohn, Aline Laetitia Schaub, Shannon Christa David, Laura José Costa Henriques
It is now well-established that respiratory viruses can be transmitted by the airborne route, yet the parameters modulating the infectivity of viruses in aerosol particles are poorly understood. Through a combined experimental and computational approach, w ...
2023Aerosol pH is an overlooked driver of airborne influenza and coronavirus inactivation
The current pandemic has added to the growing evidence that respiratory viruses can be transmitted by the airborne route. Non-pharmaceutical interventions, such as mask wearing or ventilation, aim to reduce the public health burden of respiratory diseases ...
2023A new chapter of healthy indoor air: antiviral air treatments
Aerosol transmission remains a major challenge for the control of respiratory viruses. To date, prevention strategies include masks, vaccinations, physical distancing, travel restrictions, and lockdowns. Such measures are effective but come with heavy soci ...
Hoboken2023Bacterial colonization in realistic environments: how mechanics impact biofilm formation in the wild and during infection
A variety of physical inputs acts onto bacteria in nature. However, these are most often ignored in the studies of their physiology. There is now increasing evidence indicating that bacteria respond to physical stimuli, including mechanical forces. Yet, qu ...
EPFL2023CSF-contacting neurons respond to Streptococcus pneumoniae and promote host survival during central nervous system infection
Ludovic Pierre Gustave Keiser, Laura Desban
The pathogenic bacterium Streptococcus pneumoniae (S. pneumoniae) can invade the cerebrospinal fluid (CSF) and cause meningitis with devastating consequences. Whether and how sensory cells in the central nervous system (CNS) become activated during bacteri ...
CELL PRESS2023Viral Genetic Determinants of Prolonged Respiratory Syncytial Virus Infection Among Infants in a Healthy Term Birth Cohort
Jacques Fellay, Zhi Ming Xu, Dylan Lawless, Thomas Junier
Background. Respiratory syncytial virus (RSV) is associated with acute respiratory infection. We sought to identify RSV variants associated with prolonged infection. Methods. Among healthy term infants we identified those with prolonged RSV infection and c ...
OXFORD UNIV PRESS INC2023The neuraminidase activity of influenza A virus determines the strain-specific sensitivity to neutralization by respiratory mucus
Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler
Respiratory mucus lining the airway epithelium constitutes an important first line of defense against infection with influenza A virus (IAV). Previous studies suggested that the inhibitory potential of mucus relies not only on the presence of decoy recepto ...
2023Expiratory Aerosol pH is a Driver of the Persistence of Airborne Influenza A Virus
To mitigate the spread of a viral disease, it is crucial to understand the factors that influence airborne virus transmission. However, the micro-environment to which the virus is exposed in expiratory aerosol particles is highly complex. The relative humi ...
