Several new papers about microbes and the built environment came out or came up in my searches this weekend, so time for another installment. Since one of the papers is about prison workers, you could play Johnny Cash’s Folsom Prison Blues while reading this post. Open Access: Coccidioides Exposure and Coccidioidomycosis among Prison Employees, California, United States – …
New “Built Environment” papers that came out in the last couple of days, covering microbes in indoor air, flooded areas in Thailand, and on money bills. Chamber Bioaerosol Study: Outdoor Air and Human Occupants as Sources of Indoor Airborne Microbes – Rachel I. Adams – PLOS ONE ..we used DNA sequencing of filter samples to assess the …
I know I am late to the game here but I am getting more and more fascinated by “chamber” studies in which people are placed in a sealed chamber and then emissions from those people (or from other things in the chamber with the people) are characterized. With ever improving sensors, particle analysis tools, mass-specs …
One of the issues that was raised in the recent Microbiology of the Built Environment conference in Boulder was sampling, specifically what and how is the material collected for subsequent biological analysis. Industrial hygienists and those tackling questions of exposure have devoted a lot of time to developing methods for how to study the indoor …
Registrants for the March AAAS Symposium are recipients today of the following message from Anette Olsen at AAAS. “I’d like to let you know that the videos of each panel is now online, but they currently remain unedited. We anticipate another two weeks before the edited versions are placed online. In the meantime, here is …
Jordan Peccia has posted the slides from his tutorial, Molecular methods for bioaerosol analysis on Slideshare. If you would like to get a quick overview of molecular-biology based methods, this is a painless, accessible way to do it. You are encouraged to post your comments and questions after you review the slideshow. We hope to …
You could say that I’m milking this one study design – one in which we surveyed the airborne microbial communities and surfaces around different units of a university housing complex – and you’d be right. But for good reason: it’s a powerful study design. We have replication of residential units of a common design across …
You can download the database of over 360 publications that report characteristics of the indoor environment along with the microbes found in the studies. Each publication is entered as a record and includes citation, abstract, keywords, organisms, substrates, and environmental conditions as reported by the authors. The database in MS Access format is searchable for …
Interested in learning more about air sampling in the built environment? Then check out the Google Hangout with several researchers on the topic posted on microBEnet. Interested in even more detail? Then check out the EPA report entitled “Determination of the Sampling Efficiency of Biosamplers to Collect Inhalable Particles”
The study of how aerosols disperse and settle is an important part of the microbiology of the built environment and there are several groups working on the topic. However, this story was the first I’ve heard about modeling this process in zero gravity. The settling of aerosols in particular is quite different in spacecraft than …
