So when I first dipped my toe into blogging on microBEnet (which I had just set up) on Feb 16, 2011 I had no idea that *nine* years later, I’d be furiously blogging about a global pandemic (and still in the Eisen lab). Since this is my *500th blog post* I just thought I’d reflect …
We are pleased to announce the publication of our manuscript titled “Modeling microbial growth in carpet dust exposed to diurnal variations in relative humidity using the “Time-of-Wetness” framework” in the journal Indoor Air. This work is a culmination of research investigating how changes in relative humidity impact microbial growth in carpet dust. Our related study …
In this post I’m going to share the published (relatively minor) corrections to our review on COVID19 and the Built Environment and use that as a hook to argue for the value of peer review. I’ve posted previously on our rush effort to get this paper out as quickly as possible, it was only about …
(cross posted to the UCD Microbiome SRP blog) What do you get when you combine UC Davis alumni, tomato seeds, and citizen science? That would be Project GASP (“Germ”-ination Alumni Science Project). I didn’t come up with the name, I swear. This project, sponsored and paid for by the College of Biological Sciences at UC …
So this work is a spinoff of a big project that we were involved in (but almost all of the work was done by Amy Pruden’s lab at Virginia Tech). In the larger project, they examined the genomes of over 100 clinical isolates of Legionella pneumophila, as well as 10 clinical isolates from patients during …
So way back in 2014 a really interesting paper came out about a family of bacteria called Christensenellaceae, which was found to be the most heritable group in the human gut microbiome. Furthermore this group (represented by Christensenella minuta) was furthermore associated with low BMI. Most intriguingly, mouse work demonstrated that the injection of cultured …
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 …
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 …
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 …
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 …
