New understanding of how bacteria build their protective cell wall solves persistent puzzler.
Using a series of chemical and genetic tricks to interrogate a dizzying cast of characters involved in the process of building a cell wall, researchers believe they have discovered the hidden identit... Read More
Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why.
When the scientists gave oral antibiotics to mice infected with Salmonella typhimurium, a bacte... Read More

Pictured is a culture of Mycobacterium tuberculosis growing colonies in the distinctive "serpentine cord" form seen in many strains of M. tuberculosis. These cords are made up of chains of cells that make chains due to a cell wall factor of MTB.
The cell wall structure of Mycobacterium is a m... Read More
In this blog post, I discuss our Summer Research Program's "Lab Themed Dessert" competion, for which one of my students created a cake "sculpture" of Bdellovibrio attacking and invading E. coli. It was tasty, informative, and fun! My student clearly thought about Bdellovibrio a LOT during the ... Read More
In a basement laboratory at the University of Pennsylvania, two roboticists have harnessed the innate sensing, swimming, and swarming abilities of bacteria to power microscopic robots. Even though their work sounds like the prologue to a dark science fiction film, Ph.D. students Elizabeth Beatti... Read More
Unknown Fungal Contaminant found on TSA plate that had been refrigerated for 1 month. Colony was raised in the center with deep groves around the colony. Green spore formation was seen in the middle with white non-spore forming hyphae towards the edges. Read More
Here’s an undeniable fact: In samples collected from seven of New York’s subway platforms, scientists discovered that we're surrounded in plumes of microbes wafting off other people’s skin. Here’s another undeniable fact: Those bacteria colonize all of our glands and follicles and the entire epi... Read More

"For 2 decades we have been devoting our work to the visualization of the previously unknown and invisible. Detailed, aesthetic, and scientifically correct we present an access into the microscopic world of biology, medicine, chemistry, technolog... Read More
I took these combined pictures after growing S. aureus ST151 and ST3028 on blood agar plates. Both strains were isolated from cases of subclinical mastitis The plates were incubated at 37 C for 24 or 48 hrs as shown in the picture. ST3028 is one of the novel strains recently identified in ou... Read More
According to the Review on Antimicrobial Resistance commissioned by the UK Prime Minister, failing to address the growing problem of drug-resistant infections could cause 10 million deaths a year and cost up to $100 trillion USD by 2050.
Now, researchers from the Hebrew University of Jerusal... Read More
In the photo series "Impermanence," South Korean artist Seung-Hwan Oh creates colorful, otherworldly portraits with a little help from some "friends" — emulsion-consuming microbes, that is.
By immersing an exposed roll of medium-format positive film in water containing these bacteria and lea... Read More
The Ebola outbreak continues to roil West Africa, with the World Health Organization announcing Thursday that the death toll has climbed to 729 in Guinea, Sierra Leone and Liberia. More than 1,300 people are infected.
To help limit the spread of the disease the U.S. Centers for Disease Contro... Read More
For patients who acquire an infection while in the hospital, each day of hospitalization increases the risk that the infection will be caused by a drug-resistant ... Read More
A simple stain done on a stock culture of Aquaspirillum serpens to look at cell shape. This culture was grown in TSB at room temperature, ~21 degrees C, for several months. Aquaspirillum is a slow grower normally found in pond water. A characteristic spiral rod can be seen in the center of ... Read More

The Liberian man who was diagnosed with Ebola virus infection after traveling to Dallas, Texas, was treated with an antiviral drug called brincidofovir. This drug had originally been developed to treat infections with DNA-containing viruses. Why was it used to treat an Ebola virus infection? Read More
The polio eradication and endgame strategic plan announced by the World Health Organization in 2014 includes at least one dose of inactivated poliovirus vaccine (IPV). Since 1988, when WHO announced the polio eradication plan, it had relied exclusively on the use of oral poliovirus vaccine (OPV)... Read More
