Lessons learned: The microbes all around us and our buildings — and Jessica Green’s Nautilus article

Illustration (from OpenScar.com) an explanation of the beginning of the spread of SARS in Hong Kong’s Amoy Gardens apartment complex where the index case was in a building 60 meters away from a building where about 45% of the 300 infected individuals at Amoy Gardens lived. Many of the other infected individuals also lived in …

Rich Corsi radio interview about “Indoor Air Quality, an Overlooked Concern”

Great two-part interview with Rich Corsi from UT Austin talking about indoor air quality.  If you’re the kind of person who stays in your house because you’re worried about the air quality outside… don’t listen to this interview because then you’ll have nowhere left to hide. First segment (starts at 9 minutes, 40 seconds) Second …

Found: “most toxic” metabolite from a very common indoor fungus

A just-published article by Desroches et al, “Extrolites of Wallemia sebi, a very common fungus in the built environment,”in the journal Indoor Air describes a previously unidentified metabolite of Wallemia sebi , a very common fungus in houses worldwide, although relatively more common in north temperate climates. The authors (including David Miller) write that it …

Infection Prevention Based Hospital Design

Health care associated infections (HAIs) also known as nosocomial infections  occurred in 4.5 out of every 100 hospital admissions in 2002 and contributed to 99,000 deaths (Klevens 2002). In the past many prevention strategies have focused on human based transmission (such as consistent hand washing) ignoring less obvious preventative measures such as those involving a …

Hospital Water May Not be as Safe as You Think

Researchers in Italy have found abnormally high levels of infectious microbes in the water from faucets at two hospitals compared to water coming in from the deeper areas of the pipes. One of the reasons is that the water is not meeting the chlorine or temperature requirement needed to eliminate harmful pathogens, such as Acinetobacter …

Skin Microbiome at the Roller Derby

Not surprisingly, the skin microbiome changes accordingly with human contact, according to this study found through PeerJ. Researchers aimed to study a high contact sport and see how the skin microbiome changes before and after a game. They used roller derby, and as anyone who has watched the movie Whip it! will know, there is a …

Microbial VOCs and Health – report from Basel conference Indoor Microbiome Symposium

Many indoor environmental investigators have attempted to use volatile organic compounds (VOCs) emitted by microbes as an indicator of the presence or potential health relevance of the indoor microbiome. These compounds emitted by microbes are generally referred to as MVOCs. The airborne concentrations of MVOCs is usually too low for characterization by the usual indoor …

Building science measurements in the Hospital Microbiome Project: Part 1

First of all, Happy Halloween everyone. I think my costume this year will be a blogger! For those that don’t know me, I’m Brent Stephens, an assistant professor in the Department of Civil, Architectural and Environmental Engineering at Illinois Institute of Technology in Chicago, IL. I call my research team the Built Environment Research Group …
