Washington, D.C.--November 17, 2015--Researchers working for the U.S. Geological Survey have identified the fungal culprit behind an often deadly skin infection in snakes in the eastern U.S. Published this week in mBio, an online open-access journal of the American Society for Microbiology, the ...

The benefits of screening prison inmates for infection with the hepatitis C virus (HCV) and treating those who test positive for the infection would extend far beyond the prison population, according to projections made by investigators from Massachusetts General Hospital (MGH) and the Universit...

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.
#HappyMicrobialHalloween, everyone! Read More
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
In a new NIH-funded study, Dr. Kumamoto and Alice H Lichtenstein, D.Sc., director of the Cardiovascular Nutrition Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University designed high fat diets containing coconut oil, beef tallow, soybean oil or a standard ...

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,...

My lucky day when I found a pot of gold while counting colonies. Found this gem while conducting biofilm research on environmental biofilms. The biofilm was taken from a rock in the nearby river. Read More
Handy graphic for engaging students in a discussion of antibiotic efficacy. Read More
It’s never a dull day for Jeffrey Lorch and his colleagues at the U.S. Geological Survey’s National Wildlife Health Center in Madison, Wisconsin who track unexplained mortality and emerging diseases in wild animals. Think of it as a cross between CSI: Animal Kingdom and a zoological CDC.
“Any... Read More
this was my first time isolated bacterial plate from strawberry fruit harvested from the field of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU),Bangladesh. My love at first sight for bacteria. Read More
Description: This is an amazing image of a possible bacterial contaminant on a blood agar. Its structure is very bizarre and almost symmetrical and it has not been identified yet. A researcher at the Blizard Institute (Dr. Lisa Miyashita) had prepared her blood agar plates for future use and had... Read More
Biofilms – the bane of dentists and cargo ships alike – are a form of surface-attached microbial growth that is especially hardy. The cellular community not only changes its genetic expression patterns to increase resiliency under harsh conditions such as chemical or immunological attack, but th... Read More
People increasingly get medical information online, so it's important for physicians to understand how antibiotic drugs are presented to the curious public. I've collected several definitions of "antibiotic" and "microorganism" to demonstrate how people might easily think colds and flu are treat... Read More
Biofilms are important in many nonmedical aspects of life – they contaminate cargo ships, food processing centers (including your kitchen), as well as occur naturally in many environmental settings. These environmental settings can be as benign as pond scum or as extreme as the hot springs of Yo... Read More
