Staying alive in the built environment

Skin-associated bacteria are abundant indoors. A comparison across studies shows that up to 30% of bacterial sequences detected indoors are associated with the human body (see Table 1 in this 2016 paper). I’ve been kind of skeptical that these sequences represented live organisms, however. Rather, I suspected the high proportion of sequences that were human-associated …

Journal Club: “Home chemical and microbial transitions across urbanization”

Another really interesting paper from Maria Dominguez-Bello and her lab and colleagues, “Home chemical and microbial transitions across urbanization”.  They’ve done some fascinating work in the past on the microbiome changes across an urbanization gradient and here they expand that work to include a bunch of chemistry data.  Definitely worth a read for anyone interested …

How does flooring type impact your indoor chemistry and indoor microbiology?

Carpets are a favored flooring type. They can be soft, cozy, and warm – and help with keeping noise levels down. Carpet can even help prevent injury. While these attributes are well recognized, what is less known is how carpet compares with other flooring types in affecting your indoor environmental exposures. To help address this …

Journal Club: “Pre- and post-sequencing recommendations for functional annotation of human fecal metagenomes”

This is a pre-print that just came out from several UC Davis colleagues.  I actually think the title is a bit misleading because these recommendations are a lot broader than just human fecal metagenomes.  Definitely worth a read! Abstract below: Background Shotgun metagenomes are often assembled prior to annotation of genes which biases the functional …

Network analysis of the Sloan-funded MoBE program publications

~15 years after the first project was funded, the Sloan “Microbiology of the Built Environment” program has pretty much wrapped up.  Here at microBEnet, we wanted to take a deeper look at the impact of the program on the published literature in the field.  There were over 300 publications from the program through the end …

The report from Kaunas: ISES-ISIAQ 2019

Last week, the International Societies of Exposure Science and Indoor Air Quality had their joint meeting in Kaunas, Lithuania. The meeting featured a lot of great research on topics ranging from the thermal comfort of clothes to exposure to heavy metals from e-cigarettes and everything in between. While we can’t summarize the whole meeting here, …

Integration of Biology and Chemistry for Indoor Environmental Quality at ISES-ISIAQ 2019

By Pudelek (Marcin Szala) – Own work, CC BY-SA 3.0, Link The International Societies for Exposure Science and Indoor Air Quality are having a joint meeting August 18-22, 2019 in Kaunas, Lithuania. Grantees from both the Microbiology of the Built Environment and Chemistry of Indoor Environments programs will feature in several sessions. In addition, there …

A different suite: distinct fungal communities in water-damaged homes

How microbial profiles differ between water-damaged and dry buildings is not well known. It’s only logical that where moisture is available indoors, microorganism will grow. Yet, measured microbial products do not show consistent differences between wet and dry homes. Because wet homes are associated with a variety of health risks, it’s important to identify the …
