Researchers discover 'acquired' DNA key to certain bacterial infection

Researchers announced this week the discovery of a mechanism by which Mycobacterium avium -- a bacterium which can result in serious lung infections and is prevalent in emphysema and AIDS patients among others -- infects tissue cells or "macrophages" and thus compromises the body's immunity.

1. UGA scientists discover bacterial 'switch gene' that regulates oceans' sulfur emissions into the air
   10-26-2006 · EurekAlert!
   A team of researchers, led by marine microbial ecologist Mary Ann Moran at the University of Georgia, has discovered a bacterial "switch gene" in two groups of plankton. This gene helps determine whether certain marine bacterioplankton convert a sulfur compound to one that rises into the atmosphere and affects the earth's temperature or remains climatically inactive in the seas.

2. UCSD researchers discover internal compass of immune cell
   12-14-2006 · EurekAlert!
   Researchers at the UCSD School of Medicine have discovered how neutrophils -- specialized white blood cells that play key roles in inflammation and in the body's immune defense against bacteria -- navigate to sites of infection and inflammation. These findings could potentially lead to new treatments for serious infections and inflammatory diseases in patients.

   12-02-2007 · EurekAlert!
   Wellcome Trust researchers have identified a key gene involved in the disease lupus, which affects around 50,000 people in the UK, mostly women. The lead researcher behind the study has called for more patients to volunteer DNA samples to enable them to further study the underlying causes of the disease.

   08-07-2007 · EurekAlert!
   Researchers recently identified how a regulatory protein called Bcl-3 helps to control the body's inflammation response to infection by interfering a critical biochemical process called ubiquitination. Their findings open new avenues for developing therapies to treat such diseases as sepsis, diabetes and rheumatoid arthritis.

   08-22-2007 · EurekAlert!
   A new study spearheaded by the University of Pittsburgh School of Medicine has determined that environmental monitoring of institutional water systems can help to predict the risk of hospital-acquired Legionella pneumonia, better known as Legionnaires' disease. Reported in the journal Infection Control and Hospital Epidemiology, the 20-hospital study also calls for reconsideration of the current national infection-control policy to include routine testing of hospital water systems for Legionella, the bacterial group associated with Legionnaires'.

   09-06-2007 · EurekAlert!
   A team of researchers led by biochemists at the University of Georgia propose that T. b. brucei actually does infect humans but that the infection triggers release of hemoglobin from red blood cells. Hemoglobin appears to "arm" the human innate immune system by binding to a small fraction of high density lipoprotein (HDL), or "good cholesterol." The hemoglobin-HDL complex then becomes a super toxin and clears the body of trypanosomes.

9. Your genes may hold key to how sick you get from the flu
   11-03-2006 · EurekAlert!
   With the help of some high tech equipment, well-defined mouse models and analytical know how, researchers are trying to understand why a flu virus kills some people but not others. Studies to be presented at "Physiological Genomics and Proteomics of Lung Disease" found that a strain of mice more likely to die of influenza infection mounts a dramatically enhanced immune response in the lungs compared to a strain of mice that generally develops milder disease.
