Is it possible that our personal hygiene routines make us too clean? Are we soaping and cleansing away friendly microbes that help preserve skin health? A study presented at the 5th American Society for Microbiology Conference on Beneficial Microbes in Washington, DC, provides food for thought o... Read More
In February 2014 I wrote about children in California who developed a poliomyelitis-like paralysis, also called acute flaccid paralysis or AFP. However, the cause of this paralysis was not known. The CDC has released its study of these cases and concludes “The etiology of AFP with anterior myeli... Read More
A compound found in green tea may trigger a cycle that kills oral cancer cells while leaving healthy cells alone, according to Penn State food scientists. The research could lead to treatments for oral cancer, as well as other types of cancer.
Earlier studies had shown that epigallocatechin-3... Read More
Bovine viral diarrhea virus infections result in one of the most costly diseases among cattle with losses in U.S. herds estimated at $2 billion per year, according to professor Christopher Chase of the South Dakota State University Veterinary and Biomedical Sciences Department.
"It is an immu... 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
Oxytricha trifallax lives in ponds all over the world. Under an electron microscope it looks like a football adorned with tassels. The tiny fringes are the cilia it uses to move around and gobble up algae. What makes Oxytricha unusual, however, is the crazy things it does with its DNA.
Unlike... Read More
A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit its infection, manipulates its victims to die in the vicinity of the colony, ensuring a constant supply of potential new hosts, according to researchers at Penn State and colleagues at Brazil's Federal U...

Researchers from the Institute of Microbiology at ETH Zurich have discovered a new protein with antibiotic properties in a mushroom that grows on horse dung. Researchers are now exploring the various potential applications.
Microbiologists and molecular biologists at ETH Zurich and the Univer... Read More
Up to 1 in 25 patients with hospital-acquired infections. It may be that standard hand-washing and sterilization procedures in hospitals aren't enough, which is where these new fabrics that can kill bacteria come in.
University researchers in Australia have shown how cotton fabrics impregnate... Read More
Scientists looking for Ebola in bats have identified 16 other viruses in the animal which could jump to humans and potentially cause a disease outbreak on a similar scale to the West African crisis, a health security expert said on Friday.
Humans can contract Ebola from bats, which are carrie... Read More
As the world experiences a wakeup call about the rise of drug-resistant infections, a new approach to creating smarter, “programmable” drugs could combat the two major problems with life-saving drugs today.
On the one hand, today’s antibiotics work a little too well. They not only kill infect... Read More
News that a stomach bug is becoming resistant to antibiotics is alarming, but before you start fearing the so-called new bug, there are a few things you should know.
The Centers for Disease Control and Prevention reported this week that the bacteria Shigella sonnei has become resistant to cip... Read More
Dear Vincent, Dickson and Daniel,
I think the latest case describes cutaneous furuncular myiasis.
The lesion on the young man's buttock is suggestive of a botfly infection with the larvae most likely of the species Derm... Read More
Treating dairy cows and other farm animals with antibiotics and then laying their manure in soil can cause the bacteria in the dirt to grow resistant to the drugs. But a study now suggests that the manure itself could be contributing to resistance, even when it comes from cows that are free of a... Read More
Conjugal plasmids provide microbes with full complements of new genes. Conjugal plasmid transfer is deemed responsible for the rapid spread of antibiotic resistance among microbes. While broad host range plasmids are known to confer transfer abilities to diverse hosts in pure culture, the extent... Read More
Last week two American aid workers who had contracted Ebola while working in west Africa were released from a U.S. hospital and pronounced “recovered.” They had been flown to Emory University Hospital in Atlanta from Liberia earlier this month to receive care in the hospital’s specialized infect...

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
Researchers at the University of Michigan are studying the ecology of microbes in the GI tract in hopes of developing novel diagnostic tests and effective treatments for intestinal disease. How are they studying this? By creating tiny gut ecosystems! Using undifferentiated stem cells, the inv... Read More
Many drinking water treatment facilities worldwide disinfect water with ultraviolet light because it’s quick and efficient, kills protozoa such as Giardia, and doesn’t introduce potentially harmful disinfection by-products. But a new study shows that UV treatment alone can push bacteria into a d... Read More
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
