How HIV turns food-poisoning into lethal infection

Animal study reveals mechanism behind rise in salmonella bacteremia in AIDS patients Nearly half of all HIV-positive African adults who become infected with Salmonella die from what otherwise would be a seven-day bout of diarrhea. Now, UC Davis School of Medicine scientists have discovered how salmonella becomes lethal for AIDS patients. Their findings also implicate a mechanism by which HIV evades the powerful drugs used to treat AIDS.

Possible inhibitors against X-DR TB discovered

Researchers based at South Africa's CSIR have made a breakthrough in isolating five compounds that show efficacy against X-DR TB, the virulent strain of tuberculosis that has gripped the world. X-DR (extensively drug-resistant tuberculosis, those strains of TB resistant to both first and second line drugs), leaves infected people virtually untreatable with currently available anti-TB drugs.
