Recent research published in the Journal of Bacteriology is focused exactly on this question: how do bacteria transfer antibiotic resistance genes? In the current article, Drs. Dominic Poulin-Laprade and Vincent Burrus examine the mechanism of gene transfer in Vibrio cholerae, the bacterium that... Read More
Hear that little voice in your head telling you to skip a second slice of pumpkin pie? It might be coming not from your conscience, but from the masses of bacteria in your stomach.
Experiments in mice and rats suggest that certain microbes living in your body as part of the gut microbiome hav... Read More
Nitrate reduction test for the reduction of nitrate in nitrate media, to determine if the bacteria contains nitrate and/or nitrite reductase. Organism were incubated for 48 hr's at 37 degree's in nitrate media then reagents added.
Nitrate broths after the addition of 10 drops re... Read More
An experimental vaccine to protect against the mosquito-borne illness chikungunya is being tested in a Phase 2 trial sponsored by the National Institutes of Health. Results from an initial trial of the vaccine, which was developed by scientists at the NIH National Institute of Allergy and Infect... Read More
A gene that lets bacteria resist polymyxins—the last line of antibiotic defense we have left—has shown up in widespread bacteria samples from pigs and patients in south China, including strains with epidemic potential. Read More
Unknown organism, possible Bacillus spp, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was a light brown and mat. The center of the growth was smooth with rhizoid like growth on the edges which were mucoid... Read More

Although there has been some movement toward more judicious use of antibiotics, there are still people who take the drugs thinking it will help the common cold, and dentists who regularly prescribe antibiotics for patients prior to some common oral surgeries like third molar extraction.
These... Read More
I would like to see a Twitter hash tag for microbiologically themed Jack-o-Lanterns for Hallowe'en!
In my Microbiology course here at the University of Puget Sound, my student Ruth created this bacteriophage inspired pumpkin art.

Unknown organism, possible yeast or Bacillus, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow and mucoid . There are numerous rings of growth (looks like layers of rope) with lobate margins.... Read More
Unknown organism, possible yeast, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow, mat in the center and mucoid towards the outside. There are several rings of growth with each ring havin... Read More
I enjoy mixing Hallowe'en with my classes. In this blog post, I show how my microbiology students do exactly that, with humor and style. In addition, my freshman writing students do the same with their course on symbioses and parasitism. Enjoy...and #HappyMicrobialHalloween! Read More
The Nature of Death explores the possibilities of life being created through death. With the growth of similar looking bacteria in my samples, I am able to exhibit that life grows post-mortem and allows beautiful nature to coalesce around it. Having taken samples of gravestones of a U.S. World W... Read More
Extracellular vesicles are membrane-bound structures that are released away from cells into the environment. These vesicles carry signaling molecules, nutrient scavenging molecules, immune-modulating molecules – the list goes on and on. Every cell type examined produces vesicles, too: bacterial,...
