Potential Flu Pandemic Lurks in Birds, Pigs
May 13, 2013 1:01 pm | News | CommentsIn the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people. A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically similar to the 1968 strain and have the potential to generate a pandemic if they leap to humans.

Bacteria Interferes with Malaria Transmission
May 10, 2013 11:58 am | News | CommentsMosquitoes are deadly efficient disease transmitters. Research, however, demonstrates that they also can be equally adept in curing diseases such as malaria. A new study shows that the transmission of malaria via mosquitoes to humans can be interrupted by using a strain of the bacteria Wolbachia in the insects.
Colonized Bacteria Follow Economic Strategy
May 10, 2013 11:14 am | News | CommentsBacteria on a surface wander around and often organize into highly resilient communities known as biofilms. It turns out that they organize in a rich-get-richer pattern similar to many economies, according to a new study. This is the first study identify the strategy by which bacteria form the micro-colonies that become biofilms, which can cause lethal infections.

May 6, 2013 9:43 am | News | CommentsThe tick-borne Lone Star virus has been conclusively identified as part of a family of other tick-borne viruses called bunyaviruses, which often cause fever, respiratory problems and bleeding, according to new research. What made the work especially promising was the speed at which the virus was definitively identified.
Speedy Diagnostic Device Adapted for Bacterial Infections
May 4, 2013 8:00 pm | by Mass General | News | CommentsA handheld diagnostic device that MGH investigators first developed to diagnose cancer has been adapted to rapidly diagnose tuberculosis and other important infectious bacteria. New research describes portable devices that combine microfluidic technology with nuclear magnetic resonance (NMR) to not only diagnose these important infections, but also determine the presence of antibiotic-resistant bacterial strains.
Bacterial Defense System Has Valuable Genes
May 1, 2013 9:45 am | News | CommentsEven bacteria have a kind of “immune system” they use to defend themselves against unwanted intruders– in their case, viruses. Scientists are now able to show that this defense system is much more diverse than previously thought and that it comes in multiple versions.
SARS Treatment Works on Novel Coronoavirus
May 1, 2013 9:27 am | News | CommentsScientists used lab-grown human lung cells to study the cells’ response to infection by a novel human coronavirus (called nCoV) and compiled information about which genes are significantly disrupted in early and late stages of infection.
Hospitals See Surge of Superbug-fighting Products
April 29, 2013 3:01 am | by MIKE STOBBE - AP Medical Writer - Associated Press | News | CommentsThey sweep. They swab. They sterilize. And still the germs persist. In U.S. hospitals, an estimated 1 in 20 patients pick up infections they didn't have when they arrived, some caused by dangerous 'superbugs' that are hard to treat. The rise of these superbugs, along with increased pressure from the government and insurers, is driving hospitals to try all sorts of new approaches to stop their spread.
New Antibodies Help Fight Stubborn Bacteria
April 25, 2013 12:03 pm | News | CommentsIn an advance toward coping with bacteria that shrug off existing antibiotics and sterilization methods, scientists are reporting development of a new family of selective antimicrobial agents that do not rely on traditional antibiotics.
China Bird Flu Jumped Directly from Chickens
April 25, 2013 11:48 am | by The Associated Press | News | CommentsChinese scientists have for the first time found strong evidence of how humans became infected with a new strain of bird flu: from chickens at a live market. Chinese scientists compared swabs from birds at markets in eastern China to virus samples from four patients who caught the new H7N9 virus. The scientists found the virus from one patient was nearly identical to one found in a chicken.
New Flu Passes More Easily from Bird to Human, WHO Says
April 24, 2013 3:35 am | by GILLIAN WONG - Associated Press - Associated Press | News | CommentsA lethal new strain of bird flu that emerged in China over the past month appears to jump more easily from birds to humans than the one that started killing people a decade ago, World Health Organization officials said Wednesday. Scientists are watching the virus closely to see if it could spark a global pandemic.

Protein Discovery Prevents HIV Reservoirs
April 17, 2013 1:11 pm | by Einstein | News | CommentsResearchers have discovered how the protein that blocks HIV-1 from multiplying in white blood cells is regulated. HIV-1 is the virus that causes AIDS, and the discovery could lead to novel approaches for addressing HIV-1 "in hiding"– namely eliminating reservoirs of HIV-1 that persist in patients undergoing antiretroviral therapy.

TB Fighter, Promoter Reveals Split Identity
April 12, 2013 11:17 am | News | CommentsTumor necrosis factor– normally an infection-fighting substance produced by the body– can actually heighten susceptibility to tuberculosis if its levels are too high. A new study shows how excess production of this disease-cell destroyer at first acts as a TB germ killer. But later the opposite occurs: Too much tumor necrosis factor encourages TB pathogens to multiply in the body.
Medication Nation: Study Shows Antibiotic Overuse
April 10, 2013 4:59 pm | by MIKE STOBBE - AP Medical Writer - Associated Press | News | CommentsU.S. doctors are prescribing enough antibiotics to give them to 4 out of 5 Americans every year, an alarming pace that suggests they are being overused, a new government study finds.

Tiny Proteins Prevent Bacterial Gene Transcription
April 10, 2013 10:10 am | News | CommentsIn the search for new antibiotics, researchers are taking an unusual approach: They are developing peptides, short chains of protein building blocks that effectively inhibit a key enzyme of bacterial metabolism. The road from gene to protein has an important stop along the way: ribonucleic acid, or RNA.
