Connectedness, human use of buildings shape indoor bacterial communities

Genetic sequencing exposes diversity of microbial biodiversity in buildings.

The location, connectedness, and human use patterns in a building may influence the types of bacteria they house, according to a study published in PLOS ONE on January 29, 2014 by Steven Kembel from the University of Québec in Montréal, Canada and colleagues.

Humans spend a majority of their time in buildings, which have their own ecosystems of microorganisms. Microbes living in and on buildings or people may play a critical role in human health and wellbeing. To understand how design choices and human use influence the bacteria in the building, researchers collected microbiological, architectural, and environmental data in 155 rooms in a 4- story multiuse classroom and office building on the University of Oregon campus. They used filtered vacuum cleaners to collect dust in offices, classrooms, hallways, bathrooms, and storage closets and genetically sequenced the bacteria. Read more…
