Immune system's distress signal tells bacteria when to strike back

The human opportunistic pathogen, Pseudomonas aeruginosa, has broken the immune system's code, report researchers from the University of Chicago, enabling the bacteria to recognize when its host is most vulnerable and to launch an attack before the weakened host can muster ...

Here are three examples. 1) Pneumocystis, an opportunistic pathogen causing mortality in AIDS patients and immunocompromised individuals, is now known to be a fungus, indicating a different treatment regimen is needed. 2) Phytophtora, an organism causing potato blight, such as the one that caused the Irish f...

Scientists determine structure of enzyme that disrupts bacterial virulence

Tuberculosis still a risk for patients receiving HIV drugs

.... Girardi said. Since TB is a potentially deadly opportunistic infection for patients with HIV, doctors need to be aware of the risk and take certain precautionary measures. "HIV-infected patients, even when treated with HAART, remain at increased risk of developing tuberculosis," Dr. Girardi said. "Thus, physic...

UCLA scientists discover immune response to HIV differs, even in identical twins
