Substance protects resilient staph bacteria

...y fatal but can lead to serious conditions such as sepsis (widespread toxic infection) and endocarditis (inflammation of the lining of the heart and its valves). Because of the ability of PGA to promote resistance to innate immune defenses, learning more about the protein could lead to new treatments for S...

Community MRSA is re-emergence of 1950s pandemic, study suggests

...taphylococcus aureus bacteria caused skin lesions, sepsis and pneumonia in children and young adults around the world. This pandemic of both hospital and community acquired infections waned throughout the 1960s as the antibiotic meticillin was used to treat these infections. Now researchers have shown that...

HIV accessory protein disables host immunity via receptor-protein intermediary

...cked out and found that their cells were immune to sepsis (pathogens and their toxins in the blood), because the NF-kB molecules did not go into overdrive, kicking up inflammatory molecules called cytokines. This data demonstrate that Vpr attacks PARP-1 activity, so the mice are immune to toxins created by ...

Lack of a key enzyme dramatically increases resistance to sepsis

... could be a potentially useful in the treatment of sepsis and other inflammatory and immune disorders. The...ese individuals are far more susceptible to severe sepsis and have a significantly increased risk of dying from it." Sepsis, the body's inflammatory respons...

Less is more, gene study shows

...people who lack the gene are better able to resist sepsis than those who have a working copy. "This is another indication that loss of the gene would be good for the individual, but it doesn't show that the gene became a pseudogene because of that advantage." However, using population genetics techniques, ...

Mayo Clinic researchers challenge sepsis theory

...has challenged the accepted theory on the cause of sepsis -- a condition in which the body's cells generate ...nce/journal/14714914 . Their findings suggest that sepsis begins with a change in certain cellular receptors that then provoke widespread inflammation, even i...

Cell wall of pneumonia bacteria can cause brain and heart damage

...es. S. pneumoniae is a leading cause of pneumonia, sepsis (a potentially life-threatening bloodstream infection) and meningitis (inflammation of the membranes surrounding the brain and spinal cord). The St. Jude team found that pieces of cell wall from S. pneumoniae that escape from the bloodstream enter...

Gene chip technology shows potential for identifying life-threatening blood infection

Researchers identify new weapon to fight deadly bacterial sepsis
