A Walk in the Park: Influence of Natural Co‐Exposure to Grass Pollen and Fungal Spores on Nasal Mycobiome and Cytokine Responses

Clinical &Experimental Allergy, EarlyView.
Volunteers stayed 3 h indoors and followed 1 h outdoors in a flowering meadow. Nasal mycobiome was analysed and aeroallergen content measured in nasal filters. Airborne fungal spores were quantified and fungal isolates were sequenced. Isolated fungal spores were used for stimulation of nasal epithelial cells.

Microbiology and atmospheric processes: Biological, physical and chemical characterization of aerosol particles [PDF]

, 2008
The interest in bioaerosols has traditionally been linked to health hazards for humans, animals and plants. However, several components of bioaerosols exhibit physical properties of great significance for cloud processes, such as ice nucleation and cloud

Characterization and parameters for the effectiveness of a UV‐C device for infection control in dental clinics

Photochemistry and Photobiology, EarlyView.
Purpose‐built UV‐C device achieves over 90% disinfection of high‐touch dental clinic surfaces. Abstract Healthcare‐associated infections (HAIs) remain a significant concern in dental settings, especially in light of increasing antimicrobial resistance.

Propagation of viral bioaerosols indoors

PLOS ONE, 2021
Here we look into the spread of aerosols indoors that may potentially carry viruses. Many viruses, including the novel SARS-CoV-2, are known to spread via airborne and air-dust pathways. From the literature data and our research on the propagation of fine aerosols, we simulate herein the carryover of viral aerosols in indoor air.

Exploring toilet plume bioaerosol exposure dynamics in public toilets using a Design of Experiments approach

Scientific Reports
Bioaerosols generated during toilet flushing can contribute to the spread of airborne pathogens and cross-contamination in indoor environments. This presents an increased risk of fomite-mediated or aerosol disease transmission.
