New approach to cystic fibrosis treatment

Researchers at the University of Pennsylvania School of Medicine have discovered that an enzyme produced by lung-infecting bacteria further shuts down a protein that is defective in cystic fibrosis patients.

Method of mass-producing disease-fighting antibodies entirely within bacteria

The group led by Dr. George Georgiou developed the new antibody-production approach to improve upon processes used previously to identify new drugs.

Vaccines to prevent or slow the growth of cancerous tumors

Mayo Clinic researchers have designed a new strategy in the promising field of cancer vaccine research that's proven to be successful in boosting T cells - the immune builders akin to a super defense force against cancer cells.

Researchers use bacterium to obtain biopreservatives from food

The research group "Estudio de sustancias antagonistas producidas por microorganismos" (Antagonistic substances produced by microorganisms), part of the Microbiology Department of the University of Granada, has succeeded in isolating enterocin AS-48, which could have a medium-term use as food biopreservative.

Researchers develop technique to concentrate, manipulate and separate a wide class of swimming bacteria

The technique is based on the transmission of tiny electric current in a very thin film sample cell containing a colony of bacteria. The current produces electrolysis that changes the local pH level in the vicinity of the electrodes.

Bacteria barge inside guard cells and initiate a powerful immune response

Immune cells that are the body's front-line defense don't necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought.

Staph infections among hospitalized patients are on the rise

The study, conducted by Gary Noskin, MD, infectious disease specialist and associate chief medical officer at Northwestern Memorial Hospital, also revealed that the increase in staph infections is resulting in millions of dollars of excess healthcare costs due to longer hospitalizations.

Most-at-risk nursing home residents to be tested for superbugs

A Johns Hopkins study of adult patients admitted to The Johns Hopkins Hospital showed that patients who resided in nursing homes or other kinds of long-term care facilities at any time within the last six months were far more likely than other adult patients to carry or be infected with a drug-resistant superbug.

Johns Hopkins to test all children for 'superbugs'

Infection control and critical care experts at The Johns Hopkins Hospital have ordered testing for the two most common hospital superbugs for every child admitted to its pediatric intensive care unit.

New genetic risk factors for Crohn's disease

An international research team , including investigators from Massachusetts General Hospital (MGH) and the Broad Institute of Harvard University and Massachusetts Institute of Technology, has identified several novel genetic variations associated with the risk of Crohn's disease.

New player in the development T-cell acute lymphoblastic leukemia

Leuven, Belgium -- Leukemia, or cancer of the bone marrow, strikes some 700 Belgians each year.

Rhythmic motion of the lungs clears bacteria

While working to find novel ways to treat the life-threatening disease of cystic fibrosis, researchers at the University of North Carolina have discovered that the rhythmic motion of the lungs during normal breathing is a critical regulator of the clearance of bacteria and other noxious materials.

First successful attempt to determine the structure of RfaH transcription factor

The results of a new study suggest that bacteria that cause diseases like bubonic plague and serious gastric illness can turn the genes that make them infectious on or off.

Bacteria can barge inside immune cells

Immune cells that are the body's front-line defense don't necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought. In a new paper, University of Michigan scientists describe their findings that bacteria can barge inside these guard cells and independently initiate a powerful immune response.

FDA approves GlaxoSmithKline's antibacterial Altabax

GlaxoSmithKline has announced that the U.S. Food and Drug Administration (FDA) has approved its antibacterial Altabax for the topical treatment of impetigo due to susceptible strains of Staphylococcus aureus or Streptococcus pyogenes, the two most common types of bacteria in this kind of infection.

FDA approves Altabax ointment for impetigo

The Food and Drug Administration (FDA) approved Altabax (retapamulin ointment) for topical treatment of impetigo, a skin infection caused by bacteria.

New CDC data show increases in E.coli, salmonella and vibrio

The Centers for Disease Control and Prevention's latest report shows that infections from E. coli O157:H7, Salmonella, and Vibrio are all on the rise. E. coli cases reported to CDC's FoodNet rose 50 percent since 2004, and Vibrio, another potentially deadly pathogen in shellfish, rose a whopping 78 percent since FoodNet began (1996-1998).

Vitiligo gene linked to other autoimmune diseases

In a study appearing in the March 22 New England Journal of Medicine, scientists supported by the National Institutes of Health's National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) have discovered a connection between a specific gene and the inflammatory skin condition vitiligo, as well as a possible host of autoimmune diseases.
