Hello TWiMsters! I recently discovered the trifecta that is the TWi series, and now I can’t get enough of your discussions of all things micro. For graduate students like myself, keeping up with the scientific literature can all too easi... Read More
A common ingredient in antibacterial soap can be found in some people's noses, and the presence of this ingredient could be promoting the colonization of Staph bacteria, according to a small new study in the journal mBio.
Researchers from the University of Michigan found triclosan in the nasa... Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Image ... Read More
Analytical Chemistry Researchers have created a spinning disk that can quickly tell--within 30 minutes--if food samples contain Salmonella. The most widely-used method to test for the pathogen involves growing out samples on petri dishes and can take days so this has potential to be much quicker... Read More
A bill to track drug-resistant infections has been introduced in Florida, inspired in part by FRONTLINE’s Hunting the Nightmare Bacteria.
The bill, sponsored by Rep. Janet Adkins, a Republican, requires the state health department to maintain an online record of the type and location of any a... Read More
On the list of substances you really don’t want to mess with, elemental mercury is pretty high up. Inhalation or absorption of the volatile metal can quickly lead to irreversible poisoning. Unfortunately, Hg is also a hallmark of industrial society.....Mercury-resistant bacteria carry a collecti... Read More
esearchers from Harvard-affiliated Brigham and Women’s Hospital (BWH) and Harvard Medical School (HMS) have estimated that around 1 million children contract tuberculosis (TB) annually — twice the number previously thought to have the disease and three times the number of cases diagnosed every y...

Researchers from the National Collection of Yeast Cultures (NCYC) at the Institute of Food Research (IFR) have identified a new globe-trotting yeast species that lives on tree-associated beetles. This new species demonstrates the importance of preserving biodiversity, as yeasts like this may hel... Read More
While it is true that Taenia saginata tends to be benign as helminthic infestations go in humans, the same cannot be said for Taenia solium.
In both cases, ingestion of (encysted) larvae leads to enteric infestation wi... Read More
ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More
Serratia marcescens/Escherichia coli mix grown on TSA for 48 hrs. Serratia marcescens grows red due to prodigiosin and Escherichia coli grows opaque white. Read More
By shifting evolution into reverse, it may be possible to use “green chemistry” to make a number of costly synthetic drugs as easily and cheaply as brewing beer. Normally, both evolution and synthetic chemistry proceed from the simple to the complex. Small molecules are combined and modified to ... Read More
This week a study published in the British Medical Journal, and reported in the Daily Mail, has reported that a strain of bacteria known as Lactobacillus reuteri DSM 17938 is not effective in helping to reduce symptoms of colic in babies.
However here we examine the nature of the study, and i... Read More
The Foldscope is a fully functional microscope that can be laser- or die-cut out of paper for around 50 cents.
This bookmark-sized microscope can be assembled in minutes, includes no mechanical moving parts, packs in a flat configuration, is extremely rugged and can be incinerated after to s... Read More
We’re in the midst of an extinction crisis, and it doesn’t involve Siberian tigers. Microbiologist Martin Blaser of New York University School of Medicine says that many species of germs are disappearing from our bodies—and that’s a problem. In his new book, Missing Microbes: How the Overuse of ... Read More
Three organisms inoculated in TSB to look at tube morphology. From left to right:
Staphylococcus aureus: flocculent growth/turbid, growth throughout the tube.
Mycobacterium smegmatis: pellicle, growth at the top of the tube. M. smegmatis tends to stick to the tube and grow up the side.
Ba... Read More
