Studying the 5 second rule, antibiotic resistance genes in indoor dust and sewers, Legionella in the air, and water treatment. Microbes on the floor Longer Contact Times Increase Cross-Contamination of Enterobacter aerogenes from Surfaces to Food — Robyn C. Miranda — Applied and Environmental Microbiology ($25 for 1 day) Bacterial cross-contamination from surfaces to food can …
Microbes in the house Fungal and bacterial growth in floor dust at elevated relative humidity levels — Karen C. Dannemiller — Indoor Air ($6 to rent, $38 to own) Under sustained, elevated building moisture conditions, bacterial and fungal growth occurs. The goal of this study was to characterize microbial growth in floor dust at variable …
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, …
Microbes and humans Review: The Anthropocene: a conspicuous stratigraphical signal of anthropogenic changes in production and consumption across the biosphere – Mark Williams – Earth’s Future (OA) Biospheric relationships between production and consumption of biomass have been resilient to changes in the Earth system over billions of years. This relationship has increased in its complexity, …
So as a general rule I don’t like to pick on published papers… mostly I prefer to pick on news stories, particularly of the germaphobic variety. That being said, occasionally I see a paper that just makes me think “why is that published?”. One of my interests is the topic of antimicrobials and antibiotic resistance …
A study appearing yesterday in the Journal of Antimicrobial Chemotherapy by Min-Suk Rhee et al. found that while triclosan hand soap did kill bacterial after 9 hours, most people wash their hands for about twenty seconds and then rinse the soap off. In these circumstances, the antibacterial properties of the soap won’t do anything. Triclosan works …
Nice to see the FDA digging around into this topic: FDA seeks more data on safety of hospital hand cleaners – The Washington Post. Clearly there is some major value in having people at hospitals (and other helath care facilities) wash their hands often – this is a key step in limiting the spread of pathogens. …
I’ve had a number of conversations over the last decade that have gone something like this: Other person: “I totally agree that overuse of antibiotics and antibacterials is a problem” Me: “Do you realize how pervasive they are? They’re in toys, laundry detergent, hand soap, cosmetics, deodorants, you name it. In fact, I’ll bet there’s …
