This article by Beth Mole is a fairly detailed summary of recent research on the effects of antimicrobial soaps. As we have mentioned before on microBEnet, antimicrobials increase resistance in the environment, wildlife, and people. In addition, the soaps are often not used for long enough to confer a benefit. The article particularly focuses on triclosan and triclocarban, …
Your weekend update: Microbes and drinking water Diversity of ribosomal 16S DNA- and RNA-based bacterial community in an office building drinking water system – Jenni Inkinen – Journal of Applied Microbiology (See also their 2014 Water Research paper about same system) Next-generation sequencing of 16S ribosomal RNA genes (rDNA) and ribosomal RNA (rRNA) was used to characterize …
Set in stone Commentary: Making microbiology of the built environment relevant to design – G. Z. Brown, Jeff Kline, Gwynne Mhuireach, Dale Northcutt and Jason Stenson – Microbiome (OA) Architects are enthusiastic about “bioinformed design” as occupant well-being is a primary measure of architectural success. However, architects are also under mounting pressure to create more sustainable …
Happy New Year to you all! Here are some interesting new papers that I found over the holidays. Floors Rapid assemblage of diverse environmental fungal communities on public restroom floors – Jennifer Fouquier – Indoor Air An increasing proportion of humanity lives in urban environments where they spend most of their lives indoors. Recent molecular studies …
Researchers at Inserm/Strasbourg University have developed an antimicrobial film for implants. One of the biggest problems with implants is that they can provide ideal breeding grounds for pathogens, causing inflammation in the surrounding tissue and subsequent rejection of the implant. Often, this is avoided by prescribing patients antibiotics or coating implants in them, which of course have …
I’m really excited to have been recently awarded an Alfred P. Sloan Foundation Microbiology of the Built Environment postdoctoral fellowship. I was asked to explain a little about my plans for the project I’ll be working on for the next two years now that I officially have my PhD. As a graduate student I investigated …
A really interesting study from Rogawansamy et al explores the effectiveness of various anti-fungals on two common household fungal contaminants. They used a classic inhibitory disk assay, commonly used to test antibiotic efficacy and resistance. They tested Cavicide, Virkon, 70% ethanol, vinegar, and tea tree oil and found that the tea tree oil was most effective on both …
by Simon A. Hernandez & Nichole A. Broderick Since its launch in summer 2013, the Small World Initiative (SWI) has expanded from a small “Microbes to Molecules” course at Yale University to a multi-institutional (60 institutions in 5 countries) organization with more than 2000 students and alumni. Professor Jo Handelsman and colleagues at Yale pioneered …
A recent NPR article raised the concern of drug-resistant food poisoning. Specifically, Ciprofloxacin-resistant Shigella. This strain was imported with US travellers coming from all over the world, but has now spread around the nation. Doctors are now starting to treat multi-drug resistant Shigella using IV instead of oral antibiotics. The article states: Multidrug-resistant Shigella has caused several outbreaks …
Teixobactin has been getting a lot of press since it’s debut in the most recent publication of Nature. And rightfully so: The authors claim that the mechanisms by which Teixobactin works will make it very hard for resistance development. Surely this discovery couldn’t have come at a better time, in a period where we have …
