Gene mutation that decreases flesh-eating disease discovered by scientists

Scientists at The Methodist Hospital Research Institute in Houston recently discovered a simple gene mutation that decreases the chance people will get a flesh-eating disease called necrotizing fasciitis. Further, they proved that inactivating this section of the gene lessens the devastating disease in humans.

Scientists discover new molecular protein that protects bacteria from stomach acid

Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it's a job that usually requires a lot of energy.

Interesting aspects of bacterial sensing and signaling

Over the last fifteen years it has become increasingly obvious that bacteria are not as simple and solitary as once believed. Rather, an accumulating body of work shows that bacteria are highly complicated and social organisms, constantly sensing their surroundings and altering both their environments and behaviors to ensure survival. Direct communication between bacteria turns out to be quite common, as are coordinated intra- and interspecies responses that include the formation of highly sophisticated microbial communities.

Infecting mosquitoes with Wolbachia bacteria increases their resistance to human disease-causing viruses

Earlier this year, researchers showed that they could cut the lives of disease-carrying mosquitoes in half by infecting them with a bacterium they took from fruit flies. Now, a new report in the December 24th issue of Cell, a Cell Press publication, suggests that their strategy might do one better: The Wolbachia bacteria also makes the mosquitoes more resistant to infection by viruses that are a growing threat to humans, including those responsible for dengue fever and Chikungunya.

Growing public health threat from surge in drug-resistant strains of acinetobacter

A new study in the journal Infection Control and Hospital Epidemiology reports a surge in drug-resistant strains of Acinetobacter, a dangerous type of bacteria that is becoming increasingly common in U.S. hospitals. This study is being posted online today and will appear in the journal's February print edition.

Gene's role in immune system may suggest new treatments for childhood asthma

Pediatric researchers have identified a novel gene involved in childhood asthma, in one of the largest gene studies to date of the common respiratory disease. Because the gene, called DENND1B, affects cells and signaling molecules thought to be instrumental in the immune system overreaction that occurs in asthma, the discovery may have singled out an important target for new treatments.

Food safety advocate provides pros and cons of drinking raw milk

Unpasteurized milk — often referred to as raw milk — is at the center of a rally and court appearance today in Viroqua, Wisconsin. The controversial product can contain bacteria, like E. coli, Salmonella and Campylobacter, which can severely sicken those who consume it — bacteria removed by the pasteurization process.
