Pre-cut Salad May Encourage Growth of Salmonella

Washington, DC – November 18, 2016 – A new study from the University of Leicester shows that small amounts of damage to salad leaves in bagged salads encourage the presence of Salmonella enterica. Juices released from damaged leaves also enhance the pathogen’s ability to attach to the salad’s pl... Read More

Science Magazine: New antibiotic found in human nose

With drug-resistant bacteria on the rise, scientists believe the nose is engaging in "microbial warfare". Scientists in Germany have identified that Staphylococcus lugdunensis, found in the nose, excretes a compound they named lugdunin. This compound prevents S. aureus from growing. S. aureus ca...

Ebola adapted to easily infect people

Two studies, in the journal Cell, found a mutation increased the virus' ability to infect human cells fourfold.

Scientists have argued the mutation may have been "pivotal" in the outbreak becoming the largest in recorded history.

There were 28,616 Ebola cases in Guinea, Liberia and Sierra ... Read More

Simple food additive slows E. coli food poisoning

Polysorbate, a safe additive found in everything from ice cream to cosmetics, has been proven to slow the toxic effects of E. coli poisoning.

Had this discovery been known before the deadly 2011 E. coli outbreak in Germany, doctors may have had one more tool to save some of victims.

The fi... Read More

Know thy enemy: Kill MRSA with tailored chemistry

UConn medicinal chemists have developed experimental antibiotics that kill MRSA, a common and often deadly bacteria that causes skin, lung, and heart infections. The success is due to their strategy, which found a weakness and exploited it in a way the bacteria should have trouble countering, th... Read More

Viruses Overheard Talking to One Another

Viruses may be stealthy invaders, but a study at the Weizmann Institute of Science reveals a new, chatty side of some: For the first time, viruses have been found communicating with one another. This communication – short “posts” left for kin and descendants – helps the viruses reading them to d... Read More

Memory loss caused by a virus

Well you may ask what virus ?

and I tell you West Nile Virus ( but I want to change it to WNV ). Every year when mosquito season arrives it will bring a lot of diseases . one of them is the memory loss. you may ask how does memory loss concern WNV?
THE ANSWER:

Thousands of people are liv... Read More

Bacterial Messages From Beyond?

H.P. Lovecraft fan and composer Reber Clark (https://reberclark.bandcamp.com/) collaborated with my undergraduate student Ruth Isenberg and myself on a science+music+HPL video. When a log phase culture of Photobacterium leignothi is poured into a Petri dish, and 10 second exposures are taken ev... Read More

'Farming' bacteria to boost growth in the oceans

Chemosynthetic symbionts are bacteria living inside or on the surface of animals, supplying their host with food that would otherwise be unavailable. It has long been known that these bacteria fix carbon and convert it into organic forms. Microbiologist Jillian Petersen and colleagues from the U... Read More

Anthrax capsule vaccine completely protects monkeys from lethal inhalational anthrax

Vaccination with the anthrax capsule--a naturally occurring component of the bacterium that causes the disease--completely protected monkeys from lethal anthrax infection, according to a study published online this week in the journal VACCINE. These results indicate that anthrax capsule is a hig... Read More

In search of a better diagnostic assay for emerging fungal pathogen Candida auris

Misdiagnosis can lead to severe consequences for patients, and is a serious clinical issue. The newly emerging Candida auris requires higher doses of antifungal medications to treat an infection than does C. albicans, highlighting the importance of proper diagnosis. Thus far, the most accurate d... Read More

Connecting the Food Supply and Urinary Tract Infections

An Applied and Environmental Microbiology study found ubiquitous contamination of chicken products in the United States with clinically relevant E. coli strains, which has implications for urinary tract infection transmission. A new book from ASM Press describes UTIs in detail, from virulence me... Read More

Disarming a pathogen's ability to cause disease

The anaerobic, Gram-positive Clostridium difficile is a big problem. It causes rampant diarrhea and tissue necrosis, with more than 150,000 annual cases in the United States alone. Many of the disease manifestations of C. difficile are mediated by two exotoxins that C. difficile produces: TcdA a... Read More

RNA interference is activated in human response to influenza, other important viruses

Researchers from Massachusetts General Hospital (MGH) and the University of California, Riverside, have shown for the first time that RNA interference (RNAi) – an antiviral mechanism known to be used by plants and lower organisms – is active in the response of human cells to some important virus...

Hospital Rooms and Patients Equally Likely to Transmit Pathogens

Hospital rooms, not just the patients in them, can spread germs through contact with health care personnel, a Duke Health study reports.

“This study is a good wake-up call that health care personnel need to concentrate on the idea that the health care environment can be contaminated,” said De... Read More

Rare fungus product reduces resistance to antibiotics

A team from the Vetmeduni Vienna and the University of Natural Resources and Life Sciences, Vienna succeeded for the first time in extracting the rare compound cPM from a filamentous fungus, applying a special method. Using this substance leads to increased susceptibility of a resistant pathogen... Read More

Small RNAs regulate Bacteroides nutrient use

Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More

Microbial Awards Season in Biology 350!

I like to encourage my students to explore the intersection between art and microbiology. Science + art = awesome! In any event, in this blog post, I describe two microbial art competitions in my microbiology course at the University of Puget Sound. I think my micronauts did some remarkable w... Read More
