Don’t diss microbial eukaryotes in human gut by calling them all parasites 

There is an interesting paper from Julius LukeÅ¡ et al. in PLOS Pathogens that is worth looking at for anyone who works on microbial diversity: PLOS Pathogens: Are Human Intestinal Eukaryotes Beneficial or Commensals? They basically argue (reasonably I think) that the roles of microbial eukaryotes in the human gut have been excessively interpreted as parasitic and that …

New papers and articles on microbiology of the built environment, August 17, 2015

Science papers about mosquitoes in urban parks and purses as fomites, and popular press articles about dirty menus in restaurants and filtering bacteria with book pages. Here is a good song to match the latter two: Turn the Page by Metallica. Diversity and abundance of mosquitoes (Diptera:Culicidae) in an urban park: Larval habitats and temporal variation – Antônio …

Social Media and Food Illness

Social media has a lot of utilities, but who would have thought it could be useful in tracking down food illness sources? This article from The Washington Post discusses how Twitter and Yelp have been successfully used by health agencies in New York and Chicago to preempt restaurant inspections. Although this is by no means a miracle …

Shade Balls: Preventing Algae and Evaporation Amidst California’s Drought

A recent New York Times article by Katie Rogers talks about an odd solution to California’s dwindling water supply. LA county is using small black balls that float on the surface of reservoir water to block UV and heat. This prevents both evaporation and algae growth from occurring. With California’s drought persistently eating away at our …

Microbial biofilms in water meters

Here is your song to go with this post: Something in the water by Carrie Underwood. When we drink tap water, we usually don’t really think about the bacteria that might be in there. The quality of drinking water in the US is regulated by Environmental Protection Agency (EPA) and monitored by regularly testing the water …

New papers on microbiology of the built environment, August 10, 2015

Here are the new papers on microbes in the Built Environment I found this week, about salt-loving bacteria colonizing old houses, viruses in swimming pools, sewer systems, urban water and soils, and microbiota in urban mosquitos. Here is a good ol’ country song to match this post: This Old House by Stuart Hamblen. Paid Access, review: Halophilic microbial communities in deteriorated buildings – …

Where the sausage gets made

Here is a recent article about a built environment that hasn’t been characterized before for bacterial diversity: a meat processing plant where sausages are produced. The authors sequenced the V1-V3 area of the 16S rRNA gene to characterize cold tolerant or psychrotrophic bacteria in a refrigerated meat processing plant. Psychrotolerant bacteria are bacteria that are capable of surviving in …

Linking fecal bacteria in rivers to leaky septic tanks

This article on the website of Michigan Radio had an intriguing title. Detective work traces bacteria in Michigan rivers back to leaky septic tanks – Rebecca Williams – Michigan Radio This is a nice story illustrating how the detection of marker bacteria can be used to track contamination of rivers and other environments with fecal matter, …
