Classroom dust bacteria linked to reduced lung function in children

Research presented at the European Respiratory Society Congress in Barcelona indicates that common bacteria found in classroom dust are associated with reduced lung function in children. The study, presented by Dr. Soutrik Banerjee of the University of Ferrara and the French company Alten S. A., focused on two specific bacterial groups: Streptomyces and Mycobacterium spp., which are typically found in soil, dust, and water systems.

Utilizing data from the SINPHONIE study, which spanned 22 European countries and approximately 300 classrooms, researchers measured bacterial levels in dust and assessed children's lung health via spirometry. The findings suggest that higher exposure to these bacteria in school environments may impact how effectively children's lungs can hold and exhale air, potentially affecting oxygen intake and carbon dioxide clearance.
