Trials underway for 'essential' new TB vaccine
...ainst TB is going into second stage trials. The TB bacterium
has for too long managed to stay a step ahead of human efforts as shown by the appearance, especially in HIV positive populations in Southern Africa, of a strain of tuberculosis resistant to virtually all known drugs against TB. To have a new tool fo...
Hib vaccine: A critical ally in Asia's effort to reduce child deaths

US soldiers in Iraq fighting drug-resistant bacteria after injuries
... "This observation refutes the concept that the bacterium
is acquired prior to injury among soldiers deployed to Iraq," Dr. Griffith says. "In addition, this observation adds to the ever growing body of evidence implicating nosocomial transmission as the cause of the ongoing military outbreak." Because o...
