How Cholera Bacteria Becomes Infectious

In a new study, Dartmouth researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. Buried within ToxT, the researchers were surprised to find a fatty acid that appears to inhibit ToxT, which prevents the b... Read More

Hypothesis on mystery of dengue virus infection confirmed

La Jolla Institute scientists have proved a hypothesis that said antibodies contribute to severe dengue virus-induced disease.

The findings of the La Jolla Institute for Allergy & Immunology have major implications for efforts to develop a first-ever vaccine against the dangerous infectious d... Read More

H1N1 virus' death toll as high as 17,000, CDC estimates

The H1N1 virus, also known as swine flu, may have killed as many as 17,000 Americans, according to new estimates by the Centers for Disease Control and Prevention (CDC) in Atlanta.

Though 2,498 confirmed deaths linked to the H1N1 virus had been reported to the CDC as of January 30, the agency... Read More

Mumps outbreak observed among Orthodox Jews in New York

At least 1,500 people in New York, most of them Orthodox Jews, have contracted mumps during a seven-month outbreak that began last summer in a boys camp in the Catskill Mountains, the Centers for Disease Control and Prevention reported Thursday in its Morbidity and Mortality Weekly Report. Almos... Read More

Cholera and Related Diseases: Grasping Bacterial 'Friending' Paves the Way to Disrupt Biofilm Creation

Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery, now published in the journal Science, provides a major tool to combat enter... Read More

Skier spreads cheese on leg to heal injury

Some turn to prayer. Others turn to state-of-the-art medicine. Lindsey Vonn turned to the power of fromage.

The Olympic favorite has been wrapping her injured shin in an Austrian cheese -- topfen -- to reduce inflammation.

One former Olympic trainer wasn't surprised.

"It's not bizarre a... Read More

Martian sheen: Life on the rocks

When NASA's Viking landers touched down on Mars, they were looking for signs of life. Instead, all their cameras showed was a dry, dusty - and entirely barren - landscape.

Or so it seemed. But what the 1976 Viking mission, and every subsequent one, saw was a scene littered with rocks coated w... Read More

Slime mold considers the menu before going to dinner

Hmm, a burger or salad? We use our brains to judge the nutritional value of foods. Now it seems that slime mold can make similarly complex decisions - despite being just a giant super-cell.

The ASMCUE Steering Committee invites abstract submissions on any aspect of microbiology or biology education for the poster session. This opportunity provi... Read More

Show some LOVE for environmental microbiology

One of the most unique fields within microbiology is environmental microbiology and ecology. With discovery literally underfoot, opportunities to identify new organisms and solve challenging puzzles that impact the entire planet make this area of science exciting and fun. These were just some o... Read More

Outbreaks of gastroenteritis linked to lettuce in Denmark

At least 11 linked outbreaks of gastroenteritis with a total of 260 cases have occurred in Denmark in mid January 2010. Investigations showed that the outbreaks were caused by norovirus of several genotypes and by enterotoxigenic Escherichia coli. Lettuce of the lollo bionda type grown in France... Read More

Bacteria Are Better Gene Packers Than We Thought

In microbial genomes, genes are typically depicted as linear series of separate regulatory and coding regions. This leads to the assumption that annotations done by computer to predict such arrangements completely describe the coding capacity of bacterial genomes.

However, the more complex o... Read More

New Screening System for Hepatitis C

A newly designed system of identifying molecules for treating hepatitis C should enable scientists to discover novel and effective therapies for the dangerous and difficult-to-cure disease of the liver, says Zhilei Chen, a Texas A&M University assistant professor of chemical engineering who help...

Of Archaeal Periplasm and Iconoclasm

Moselio Schaechter of the Small Things Considered blog reviews the surprising findings in the paper "Energized outer membrane and spatial separation of metabolic processes in the hyperthermophilic Archaeon Ignicoccus hospitalis" published in the recent Proceedings of the National Academy of Scie...

Best Sellers in Microbiology

I first posted this list in July 2009. Now Washington University in St. Louis has posted a new list extending from May 2009 to today. Perhaps you're a microbiology student with an interest in growing your library or maybe you're the author of one of these books! Maybe you are just looking for a ... Read More

Protection against 2009 influenza H1N1 by immunization with 1918-like and classical swine viruses

Influenza A viruses typically cause severe respiratory disease mainly in the very young or the elderly. The 2009 swine-origin H1N1 virus is unusual because it preferentially infects individuals under 35 years of age. We’ve previously noted that being older is a good defense against 2009 H1N1 inf...

A new theory of how low doses of antibioitics create antibiotic resistance

Exposure to low levels of antibiotics increases mutations in E. coli and Staphylococcus bacteria hundreds of time more than normal, making the creation of drug-resistance strains more likely, says a paper in today's edition of the journal Molecular Cell.

This finding adds to concerns about an... Read More

Shark skin used to keep germs at bay

You expect the hospital to be one of the cleanest places around. But it can actually be a safe haven for super germs that can get you very, very sick. These germs are so hard to treat that scientists are now looking to the sea for solutions.

Sharks are considered to be some of the most danger... Read More

Soil microbial testing now affordable

Many farmers are faced with the situation of diminishing returns, even where productivity is increasing.

It is not that new technology, such as precision systems, new formulations of fertilisers and chemicals, do not continue to increase productivity, but often the problem is that productivit... Read More
