Vincent and friends,


While driving around a field cutting hay lost in my science podcast playlist the episode of TWIM #61 came up and I had to listen intently as salmonella typhimurium came up as this is a common enteric issue in agriculture. When ... Read More

De-discovering pathogens: Viral contamination strikes again

Do you remember the retrovirus XMRV, initially implicated as the cause of chronic fatigue syndrome, and later shown to be a murine virus that contaminated human cells grown in mice? Another virus thought to be associated with human disease has recently been shown to be a contaminant, derived fro... Read More

MWV Episode 78 / This Week in Microbiology 64: URI and UTI at ICAAC in Denver

A recorded version of a live streaming video episode of This Week in Microbiology (TWiM), a podcast about unseen life on Earth, with Vincent Racaniello, a Higgins Professor in the Department of Microbiology and Immu... Read More

Novel treatment for gonorrhea acts like a “live vaccine” and prevents reinfection, UB animal study shows

Administered intravaginally, microsphere treatment reverses suppression of immunity and circumvents antibiotic resistance.

A new gonorrhea treatment, based on an anti-cancer therapy developed by a Buffalo startup company, has successfully eliminated gonococcal infection from female mice and ... Read More

Researchers discover new organism: Finding will help scientists understand the origins of multicellular life

Researchers at the University of Arkansas have discovered and characterized a new organism that will help scientists understand the molecular mechanisms and ancestral genetic toolkit that enabled animals and fungi to evolve into diverse, multicellular life forms.

Jeffrey Silberman, a professo... Read More

CDC sets threat levels for drug-resistant 'superbugs'

Health officials have been warning us about antibiotic overuse and drug-resistant "superbugs" for a long time. But today the Centers for Disease Control and Prevention is sounding the alarm in a new way.

For the first time, the CDC is categorizing drug-resistant superbugs by threat level. Tha... Read More

Pig-manure fertilizer linked to human MRSA infections

People living near pig farms or agricultural fields fertilized with pig manure are more likely to become infected with methicillin-resistant Staphylococcus aureus (MRSA) bacteria, according to a paper published today in JAMA Internal Medicine1.

Previous research has found that livestock worke... Read More

Predictive model a step toward using bacteria as a renewable fuel source

A new transcriptomics-based model accurately predicts how much isoprene the bacterium Bacillus subtilis will produce when stressed or nourished. This model marks a step toward understanding how changes in the bacteria's environment affect gene expression and, in turn, isoprene production. Isopre... Read More

Novel vaccine approach to human cytomegalovirus found effective

An experimental vaccine against human cytomegalovirus (CMV) infection, which endangers the developing fetus, organ transplant recipients, patients with HIV and others who have a weakened immune system, proved safe and more effective than previous vaccines developed to prevent infection by the ub...

Vaccinating cattle against E.coli O157 could cut human cases by 85%

Vaccinating cattle against the E. coli O157 bacterium could cut the number of human cases of the disease by 85%, according to scientists.

The bacteria, which cause severe gastrointestinal illness and even death in humans, are spread by consuming contaminated food and water, or by contact with... Read More

Interview of Dr. Partha Pratim Majumder (Master of Genetics)

National Institute of BioMedical Genomics (NIBMG), an autonomous Institute by the Government of India, located around 50 Kms away from Kolkata, a metropolitan city of India. This institute is known to be the only Institute in India devoted with the researches on “Biomedical Genomics”. Dr. Partha... Read More

Cause of salamander die-off found: Skin-eating fungus

A newly discovered fungus that feasts on the skin of amphibians is threatening to decimate a species of salamander in the Netherlands, according to new research.

Fire salamanders are one of the most recognizable salamander species in Europe, and are characterized by their distinct yellow- and... Read More

In fight against infections, UIC researcher aims to scramble bacteria signals

Rather than destroying bacteria to fight infections, a University of Illinois at Chicago researcher is trying to "tweak" their savvy communication networks and block the signals that lead to infection and disease.

Researchers have known for several decades that bacteria communicate through a ... Read More

Biologists Discover New Method for Discovering Antibiotics

Biologists at the University of California, San Diego have developed a revolutionary new method for identifying and characterizing antibiotics, an advance that could lead to the discovery of new antibiotics to treat antibiotic resistant bacteria.

The researchers, who published their findings ... Read More

3 germs are urgent threats to USA's health, CDC says

The overuse of antibiotics has caused three kinds of bacteria, including one that causes life-threatening diarrhea, one that causes bloodstream infections and one that transmits sexually, to become urgent threats to human health in the United States, federal health officials say in a landmark re...

Drug-Resistant Superbugs Kill At Least 23,000 People in the U.S. Each Year

Each year, more than two million people in the United States develop antibiotic-resistant infections, and at least 23,000 of them die as a result, says the first-ever national snapshot of the issue. That toll only rises when other conditions exacerbated by these infections are included in the co... Read More

UCLA researchers' smartphone 'microscope' can detect a single virus, nanoparticles

Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.

Aydogan Ozcan, a professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, and h... Read More

It’s Time for Salmonella

If one were to ask, “What happens when Salmonella infects the gut?” it might not be obvious that you’d also need to ask, “What time is it?” But indeed you’d need to know the latter to appropriately address the former. An invading Salmonella, intent on setting up camp, is trying to pitch its tent... Read More

Vaccine seems to clear AIDS-causing virus from monkeys, scientists say

A promising HIV vaccine developed by researchers at Oregon Health & Science University eradicated the virus that causes AIDS in monkeys, and scientists hope something similar can soon be tested on humans.

AIDS in non-human primates is caused by simian immunodeficiency virus, or SIV, which is ... Read More
