Researchers from the University of Nottingham have discovered that in Staphylococcus aureus infections, bacteria defective in Quorum Sensing (QS) can benefit from opting out of toxin production and can quickly outnumber other bacteria, thereby reducing infection severity.
“This opens up the i... Read More
A University of Oklahoma research team has uncovered a key to arresting the growth of thrush -- a type of oral yeast infection that sickens patients with compromised immune systems, diabetes and newborns as well as healthy individuals, who may contract the disease following antibiotic treatment ...

A trial of a new human monoclonal antibody treatment against rabies has been successful, shaping up as a potential alternative to expensive alternatives derived from horse serum or human blood.
The new cost-effective rabies therapy developed by MassBiologics at the University of Massachusett... Read More
An average 7.8 percent of children under 5 years of age in Taiwan are carriers of multidrug-resistant staphylococcus aureus (MRSA) , a type of bacteria that can cause deadly infections, a study showed Saturday.
Among children under six months, 11 percent carry the bacteria without symptoms, a... Read More
Doctors and infectious bacteria are locked in an arms race. In this ever-escalating battle, the bacteria evolve ways to avoid every drug humans throw at them.
The conflict has intensified lately as more and more bacteria — particularly those lurking in hospitals — become able to resist nearly... Read More
On episode #100 of the podcast This Week in Virology, Vincent, Alan, and Rich celebrate the 100th episode by talking about viruses with Nobel Laureate David Baltimore.

I've been having an enjoyable time on my commute lately catching up with TWiV. Today I listened to #26 (Poxviruses), which included a discussion of Tysabri and PML. I work at Millipore which sells many products that go into a MAb production train, includ... Read More
Simple peptides can organize into bi-layer membranes. This recent finding suggests a “missing link” between the pre-biotic Earth’s chemical inventory and the organizational scaffolding essential to life.
“We’ve shown that peptides can form the kind of membranes needed to create long-range ord... Read More
More people have been infected with West Nile virus in DeKalb County than anywhere else in Georgia this year, officials said.
On Friday, the DeKalb County Board of Health announced five residents have been diagnosed with the disease, including an 87-year-old woman who is still in the hospital... Read More
The world's tiniest nuclear genome appears to have "snipped off the ends" of its chromosomes and evolved into a lean, mean, genome machine that infects human cells, according to research published September 21 by University of British Columbia scientists.
Until recently, E. cuniculi, a parasi... Read More
St. Petersburg, Fla. – (Sept. 22, 2010) – Scientists and researchers seeking additional funding sources for projects that will enhance their research goals now have an alternative resource for the money they need to propel their projects forward: the general public. SciFlies.org, a new non-prof... Read More
The bacteria Salmonella enterica—a common cause of food poisoning—exploits the immune response in the human gut to enhance its own survival.
The strategy, which improves reproductive and transmission success, gives Salmonella a growth advantage over the beneficial bacteria that normally are p... Read More
All known virus particles can be placed into one of two general categories: enveloped or non-enveloped. Viruses that fall into the former category are characterized by a lipid membrane derived from the host cell, and one or more nuclecapsid proteins that interact with the viral genome. A virus t...

Development of an effective vaccine for malaria is a step closer following identification of a key pathway used by the malaria parasite to infect human cells. The discovery, by researchers at The Walter and Eliza Hall Institute, provides a new vaccine target through which infection with the dead... Read More
Pity the poor sea otter.
It's been a struggle for the furry, button-nosed critter to make a comeback since being hunted nearly to extinction along California's coast.
They get chomped by great white sharks. They must scrounge in overexploited waters to find enough shellfish to eat. Their i... Read More
Genetic mutations that supercharge a cellular garbage disposal may explain why cancer cells can thrive even as their genetic material multiplies out of control, suggests new research by Howard Hughes Medical Institute investigator Angelika Amon. Though performed in yeast cells, the work may one... Read More
Dear Mr. Racaniello and Dick,
Thanks for TWIV and TWIP as both are great shows. Such a give and take of history, information and humor. Stumbled across TWIP several weeks ago and gave it a try. My only disappointment was there were not many podc... Read More
Nine babies have died in California, and four in Australia, so far, in the worst epidemic of whooping cough in rich countries since vaccination became widespread in the 1950s. The main cause is a lack of re-vaccination, but the bacterium may also be adapting to beat vaccines.
Vaccination prot... Read More
Across the globe, the diversity of plant and animal species generally increases from the North and South Poles towards the Equator but surprisingly that rule isn't true for soil bacteria, according to a new study by Queen's University biology professor Paul Grogan.
"It appears that the rules ... Read More
