Cutting Board Companions

The authors of this new paper have really cooked up something interesting!  “Microbial Safety of Wood in Contact with Food: A Review” by Florence Aviat, et al and published in Comprehensive Reviews in Food Science and Food Safety is an 86-reference review on materials found in kitchens. Elisabeth Bik did list this in her March 7 blog of new papers, but this one …

Guest post from @northenlab on “Exometabolite niche partitioning”

Guest post from Trent Northen of LBNL. I wrote to Trent recently when I had seen a paper of his that I found fascinating: Exometabolite niche partitioning among sympatric soil bacteria.  So I asked if he would be willing to write a guest post about it. And so – he did.  It seems like the issues …

New papers on microbiology of the built environment, March 7, 2016

Microbes in the house Seasonal Dynamics of the Airborne Bacterial Community and Selected Viruses in a Children’s Daycare Center – Aaron J. Prussin II – PLOS ONE (OA) We have investigated the microbial community of the air in a daycare center, including seasonal dynamics in the bacterial community and the presence of specific viral pathogens. …

A New Way to Fight Superbugs?

There are a few news articles that have been coming out (like this one) that draw attention to this recently published paper in ISME Journal, entitled “Iron availability shapes the evolution of bacteriocin resistance in Pseudomonas aeruginosa.” The big picture of the paper was to study how resistance evolves and to explore the effectiveness of …

Hospital acquired infections – the good news and the super news (but not super in a good way) 

There are a bunch of stories starting to come out based on some press and paper releases from the CDC yesterday. One that seems well done is this from CIDRAP: CDC notes progress, threat regarding hospital superbugs | CIDRAP. Today’s CDC report focused on the six most concerning antibiotic-resistant bacteria and found better progress against them …

New papers on microbiology of the built environment, March 3, 2016

New papers about microbes in houses, food, and waste or polluted sites.   Microbes in the house Environmental Contamination in Households of Patients with Recurrent Clostridium difficile Infection – Megan K. Shaughnessy – Applied and Environmental Microbiology ($$) Households of R-CDI subjects in the peri-FMT period, and of geographically and age-matched controls, were analyzed for …

Antibiotics Susceptibility Pattern of Hospital Indoor Airborne Bacteria

Jonathan drew my attention to this paper on antibiotic susceptibility of 153 bacterial isolates collected from a hospital in Ethiopia. I thought the numerous grammatical errors in the paper would parallel with the quality of the study, but I was pleasantly disproved. In the abstract they state, “86.9% [of the 153 isolates] were resistant to …

Arthropod Diversity in Urban and Suburban Homes

A paper from Bertone et al studies indoor arthropod diversity in urban and suburban homes. They surveyed all the arthropods they could find in 50 homes in North Carolina, finding 24-128 distinct arthropod families per home! These critters were filtering in from the outdoor surroundings of the home, and most of them were benign to humans. They also found …

Cyanobacteria cells act as tiny spherical lenses

While it has long been known that some cyanobacteria move (or crawl) towards light, how these cells detect the direction and source of light was undescribed until recently. In Cyanobacteria use micro-optics to sense light direction, Schuergers et al. (2016) investigated Synechocystis phototaxis and found that each cell acts as a microscopic spherical lens, focusing an intense light spot close to the opposite side …

Microbiological consequences of indoor composting

Another interesting (and closed access) paper from Indoor Air… this time from Naegele and colleagues in France… “Microbiological consequences of indoor composting“.  Indoor composting has become more and more popular in urban areas where traditional composting isn’t an option.   Here’s a nice look at what that does to the microbial community of the location.  Abstract …
