At the Research center of the Institut universitaire de cardiologie et de pneumologie de Québec (IUCPQ), Professor Caroline Duchaine’s team studies bioaerosols and their effects on the respiratory health of exposed humans.
First, the term aerosol refers to solids or inert liquids in any gas, usually air. Bioaerosols are, in turns, aerosols composed of solid or liquid particles from 0.002 microns to 100μm carrying live microorganisms or molecules derived from living organisms (viruses, bacteria, fungi, microalgae, pollen, animal hair, plant fragments, etc.). The effects of aerosols and bioaerosols on human health are thus very different. Some infectious diseases can be transmitted by bioaerosols.
More precisely, we are interested in :
The development of detection methods for airborne respiratory pathogens using molecular biology, the exposure to mycobacteria in the workplace, the air quality in agricultural environments and the respiratory health of workers, the microbial ecology of metal working fluids and allergic alveolitis, the detection of bioterrorism agents, the detection of antibiotic resistance genes using in situ hybridization, and the aerovirology.
Members from Caroline Duchaine's team have presented their studies or will do during these events :
Some of our studies have been presented at the 4th Workplace and Indoor Aerosols conference (April 20-22, 2016, Barcelona, Spain) :
- A next generation sequencing approach for the study of fungal diversity in bioaerosols (Hamza M'Bareche, MSc student)
- Worker’s exposure to bioaerosols in biomethanisation facilities (Marie-Eve Dubuis, MSc student)
- Assessment of workers' exposure to bioaerosols in wastewater treatment plants: evaluation of the bacterial risk by the use of molecular biology tools (Vanessa Dion Dupont, MSc student)
- Bioaerosols exposure in indoor composting installations: classical and molecular approaches and preferential aerosolization (Marc Veillette, research associate)
