Rapid biophotonic detection of Legionella?

Quick post here (h/t to Paula Olsiewski for the link) about a cool-sounding new device for the rapid detection of Legionella.   I can’t say that I’m on board with the fanciful claims made in the press release (e.g. “The risk of catching fatal Legionnaires’ disease from air conditioning units has been dramatically reduced“) but the …

Legionnaires’ Disease Outbreak in Flint, Michigan

(Update:  after posting this I found that actual experts have proposed a different hypothesis) So the recent Legionnaires’ Disease Outbreak in Flint, Michigan has been getting quite a bit of press recently.   For example in the last few days here are pieces from The Atlantic, The Washington Post, and CNN. The very short version of …

What’s new in the intersection of microbiology and human use of the environment? Here are some recent papers and their abstracts. The first paper is important because it describes the microbiological conditions of the waters that will be used in the 2016 Olympics: Environmental and Sanitary Conditions of Guanabara Bay, Rio de Janeiro – Giovana …

Antibiotic resistance genes in “black gold”

Sometimes efforts to be environmentally friendly can give rise to microbial challenges. This was nicely described by Katie Dahlhausen in her recent post about water quality about green buildings. Other examples include observations that Legionella pneumophila can be contracted from shower heads and the use of low flow shower heads and lower water temperatures may increase its transmission. Likewise, wastewater (e.g., Environmental and …
