Linking antimicrobials and antibiotic resistance genes in indoor dust

Previous BioBE postdoc Erica Hartmann (now Assistant Professor at Northwestern University!), along with several BioBE researchers and members of Curtis Huttenhower’s (Harvard) and Rolf Halden’s (Arizona State) research groups, recently published a paper establishing a link between antimicrobials and antibiotic resistance genes in indoor dust. Dr. Hartmann published a post summarizing the main findings at microBEnet. The paper is freely available in the journal Environmental Science & Technology.

Microbiota of the Indoor Environment: A Meta-Analysis

Congratulations to all on this recently published paper in the journal Microbiome, from BioBE co-authors James Meadow & Ashley Bateman, with collaborators Rachel Adams & Holly Bik. This project was born during a 2013 NESCent Catalysis Meeting on “Evolution in the Indoor Biome”. Hoping to address broad-scale ecological questions with as many high-throughput sequencing datasets as possible, the published manuscript describes several significant technical and biological findings. See this microbenet post for a summary of the most important results.

New paper in PeerJ: Mobile phones reflect our personal microbiome


Our new paper on the bacterial connection between our hands and our mobile phones is out this week in PeerJ.

Also, James Meadow did an interview with PeerJ about the study and it’s implications as well as his thoughts about the PeerJ publishing experience. Worth a read if you’re thinking about publishing in open-access soon.

A round-up of recent media coverage is in the works…

What can the microbes on your chair tell us about the indoor microbiome?

What sorts of bacteria did we find in a university classroom? from BioBE Center on Vimeo.

Funny you should ask! A new BioBE study is out today in the journal Microbiome. We sampled the bacteria from surfaces all over a university classroom and found that the bacteria on those surfaces can tell you quite a bit about how we interact with those surfaces. We also made a quick film that discusses our results.

New BioBE building microbiome paper published in PLOS ONE

We’ve just published a new paper exploring the bacterial communities hanging out in the dust of a big university building, Lillis Hall. It’s the same building that we used when exploring the effects of ventilation and occupancy on airborne bacteria (published in Indoor Air). This time, we were interested in the long-term accumulation (about a decade) of indoor dust, and how microbes in dust are influenced by architecture and occupant use. We found that what you do in a room, how many people there are in a room, and how well connected rooms are, all make a big difference. We were also surprised to find that offices located right beside one another vary considerably in their dust microbial communities just based on the source of their ventilation (from a window or from a mechanical system).

One of these days, we’ll know enough about the microbes in our buildings to manage them for a healthier indoor environment. This paper helps us understand the architectural choices that we can use in the future to manage our microbes.

The paper is open access and available at PLOS ONE.

New Publication in Indoor Air

A new paper just published by members of BioBE is out now, and open access at Indoor Air journal. The study details air samples collected in classrooms at the University of Oregon, and the temporal changes that happen in indoor airborne microbial communities over the course of a week. We found that classrooms that were well ventilated very closely followed changes in the microbial communities outside of the building, but that rooms that were closed off at night and on weekends (the way buildings are often operated) retained a stagnant microbial community until the ventilation was opened up again. The paper also reports on human-associated microbes that are more commonly detected when people are in the room. This paper adds to our growing understanding of the sorts of microbes we encounter in our everyday lives in the built environment, as well as the architectural choices that drive their ecological patterns.
