Infectious diseases are the leading cause of death worldwide, so it is critical that we characterize exposure routes of infectious agents, including those resistant to antibiotics. The source of infectious agents is often attributed to the environment. But, few studies have explored what types of environmental exposure introduce opportunistic microbial pathogens or what actions may …
Many recent news stories have been discussing a case of an outbreak in a hospital in Greenville, SC that has apprently been traced to drinking water contamination. Thus this may be of interest to a variety of people. See some links below: 4th patient with GHS infection dies. Fourth bacterial infection death reported at South …
There is a paper that just was published that possibly will be of interest to those interested in studying microbial ecology of drinking water (or other water systems for that matter): Methodological approaches for studying the microbial ecology of drinking water distribution systems. Unfortunately the paper is not freely or openly available. The paper covers many topics …
Definitely worth checking out this paper from Kyle Bibby’s lab: PLOS ONE: Shift in the Microbial Ecology of a Hospital Hot Water System following the Introduction of an On-Site Monochloramine Disinfection System. A key figure in the paper is Figure 2 which I post here. The figure shows a PCA based clustering of samples based on …
Every time you bend over the public water fountain to take a drink and see the gunk at the bottom, do you wonder what’s living in it? Microbiologists do… This 2013 study from Finland collaborated on a study examining biofilms on the drinking water distribution system in office buildings. They started sampling right as the …
A group of us from Jonathan Eisen’s lab attended the General Meeting for the American Society for Microbiology (ASM) last month in Boston. A major highlight of the conference was “We Are Not Alone: Microbial Revelations of the Built Environment,” a symposium that was organized by the Junior Advisory Group that is made up of postdocs and …
Just came across this article entitled “Rainwater harvesting tanks enable spread of dangerous pathogens, study shows”. The article describes a fairly straightforward set of findings from rainwater storage tanks in South Africa. Researchers found Legionella, Klebsiella, Giardia, Salmonella, and Yersinia. Not a friendly-sounding list of bugs. However, I have the usual set of issues with …
Having been camped out in Portland, OR this week to speak at the 2014 Joint Aquatic Sciences Meeting, I woke up this morning to find a “boil water alert” had been issued for the entire city. Repeated testing over the last few days has found fecal contamination (E. coli) in the city’s reservoirs. So that means a lockdown …
Registrants for the March AAAS Symposium are recipients today of the following message from Anette Olsen at AAAS. “I’d like to let you know that the videos of each panel is now online, but they currently remain unedited. We anticipate another two weeks before the edited versions are placed online. In the meantime, here is …
Though our water undergoes many steps to become drinkable, there are many microbes that remain and have the potential to cause disease. A December study conducted in China aimed to determine the microbial compositions of water before and after treatment. This study was unique because it also sought to find the difference in microbial functions …
