(Editor's note -- this information comes from a press release, but these are interesting treatment developments.)
MRSA (methicillin-resistant Staphylococcus Aureus) and other drug-resistant bacteria could face annihilation as low-temperature plasma prototype devices have been developed to off... Read More
When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.
These "regulated errors" com... Read More
There has been a “worrisome spike” in secondary bacterial infections among Americans with swine flu, federal health officials said Wednesday, urging more people at risk to get the underused vaccine that prevents some of those infections.
Bacterial infections are a common and sometimes deadly ... Read More
