Wound dressing to stop antibiotic-resistant bacteria from spreading

University of Florida researchers have led the development of a new type of wound dressing that could keep dangerous antibiotic-resistant bacteria from spreading in hospitals, a problem that leads to thousands of deaths in the United States each year.

Cancer vaccine based on the bacterium Listeria monocytogenes, can cure mice with breast tumors

A team from the University of Pennsylvania School of Medicine has shown that by using a cancer vaccine based on the bacterium Listeria monocytogenes, they can cure mice with established breast tumors. Cancer vaccines, which are more properly described as immunotherapy, work by boosting an immune response against tumor-associated antigens.

Pneumonia doesn't appear to harm HIV-positive patients any more than those without HIV

In a two-year study that documented cases in 26 hospitals in 11 countries including the United States, Canada, South Africa, Chile and Spain, outcomes for 58 HIV-positive patients with CAP, or community-acquired pneumonia (pneumonia contracted outside of hospitals) were compared with outcomes for 174 HIV-negative patients suffering a similar severity of CAP.

Antibody in humans that quickly fights the smallpox virus

Researchers at the La Jolla Institute for Allergy & Immunology (LIAI) have made a major advancement toward protecting society against a smallpox outbreak by identifying an antibody in humans that quickly fights the smallpox virus.

Increasingly virulent Staph infections

In a "Brief Report" in the 22 September 2005 issue of the New England Journal of Medicine, researchers at the University of Chicago describe three cases of rapidly progressive and ultimately fatal Staphylococcus aureus infections in small children.

New way to create a permanent chemical bond between antibiotics and titanium

Infections associated with inserting a medical device can be devastating, painful, and cause prolonged disability, costing tens of thousands of dollars.

Daylight savings changes may help extend the life and health of people's teeth and bones

Beginning in 2007, daylight savings time will be extended by almost a month. This additional amount of daylight may also help extend the life and health of people's teeth and bones. That's because vitamin D, also known as the "sunshine vitamin," is made by the body through casual and minimal sun exposure.

Antibiotic resistance has put humans in an escalating 'arms race' with infectious bacteria

...as scientists try to develop new antibiotics faster than the bacteria can evolve new resistance strategies. But now, researchers have a new strategy that may give them a leg up in the race -- reproducing in the lab the natural evolution of the bacterial enzymes that confer resistance.

Adult sickle cell drug hydroxyurea proves effective in young children

A drug used for the treatment of sickle cell anemia in adults has now been shown to cause significant improvements in very young children with the disorder.

Use of antibiotics for acne may increase risk of upper respiratory tract infection

Individuals treated with antibiotics for acne for more than six weeks were more than twice as likely to develop an upper respiratory tract infection within one year as individuals with acne who were not treated with antibiotics, according to an article in the September issue of Archives of Dermatology.

Safe, non-surgical method of identifying brain infections such as brain abscess

Researchers at Westmead Millennium Institute have discovered a safe, non-surgical method of identifying brain infections such as brain abscess, and an accurate and rapid way of diagnosing meningitis.

Bacteria lurking in household dust produce chemicals that may trigger asthma

These bacterial chemicals, called endotoxins, particularly those found on bedroom floors, were linked with increased respiratory problems in adults.

Amnioinfusion does not reduce the risk of meconium aspiration syndrome

An international randomized trial, funded by the Canadian Institutes of Health Research (CIHR), has revealed that amnioinfusion, the infusion of saline into the uterus, does not reduce the risk of meconium aspiration syndrome (MAS), as previously believed.

Single molecular anchor holds the key to treating many types of bacterial meningitis

By blocking the molecule's anchoring ability, researchers may be able to find a way to stave off the most common serious infection of the central nervous system and a major cause of childhood death and disability. The researchers' findings appear in the September 2005 issue of the Journal of Clinical Investigation.

Macrophages kill bacteria - but not always

Macrophages are effective weapons used by our immune system to absorb and digest pathogenic intruders. Some bacteria, however, can subvert this defence mechanism and even multiply within the macrophages.

Study provides first steps toward individualized treatment of serious injuries

A multi-institutional research collaborative has begun to decipher the complex interplay of genes that underlies the body's response to major injuries.

More than 15 percent of our genes are mobilized to defend against microbial attacks

The body's overwhelming genetic defense, which has implications for the survival of patients who are severely burned or injured, was revealed in a sweeping analysis of gene activity in volunteers who were injected with a bacterial product that temporarily created flu-like symptoms.

When it comes to inflammation, too much of a good thing can be deadly

In some severely injured patients, this normal healing process can develop into a lethal, whole-body response, including bloodstream infection (sepsis) and multiple organ failure. How and why inflammation turns from healing to harming is still mysterious, so doctors can't accurately predict how each injured patient will fare.

Significant advance in understanding how enzyme can prevent certain bacteria from becoming virulent

A team of biomedical researchers from Brandeis University and the University of Texas at Austin has determined the first 3-dimensional structure of an enzyme that may be pivotal in preventing certain bacterial infections in plants, animals and humans, according to a study published in the Proceedings of the National Academy of Sciences.

Emergent Biosolutions' typhoid vaccine achieves positive results in Phase II clinical study

Emergent BioSolutions today announced positive results from a Phase II clinical study evaluating a new simplified dosing regimen for the company's next generation single dose oral typhoid vaccine. The results of the study were published in the August edition of the Journal of Infectious Diseases.
