Scientists watch agents of brain-wasting diseases invade and move within brain cells

Scientists for the first time have watched agents of brain-wasting diseases, called transmissible spongiform encephalopathies (TSE), as they invade a nerve cell and then travel along wire-like circuits to points of contact with other cells.

Anti-inflammatory protein annexin 1 may protect patients from the detrimental effects of severe inflammatory response syndrome

Severe inflammatory response syndrome, or SIRS, occurs when the body's response to an overwhelming infection becomes uncontrolled. The very immune response meant to clear the pathogen and its toxins actually causes damage to the host's own tissues when it goes into overdrive, releasing too many immune signals.

Alcohol consumption increases movement of S. pneumoniae toward the lungs

Streptococcus pneumoniae is a bacterium that can infect the upper respiratory tract and cause pneumonia, as well as infections in other parts of the body such as the bloodstream (bacteremia), lining of the brain and spinal cord (meningitis), bones (osteomyelitis), joints (arthritis), ears (otitis media) and sinuses (sinusitis).

Neutrophils dictate whether our immune system will permit or prevent bacterial infections

New research on a bacterium that can survive encounters with specific immune system cells has strengthened scientists' belief that these plentiful white blood cells, known as neutrophils, dictate whether our immune system will permit or prevent bacterial infections.

Scalpel-free surgery could reduce risk of HIV and Hepatitis exposure for health care workers in city hospitals

While the incidence of disease from HIV and hepatitis is increasing in the United States, little is known about their prevalence in patients undergoing surgery. Now, researchers have shown that nearly 40 percent of surgeries at The Johns Hopkins Hospital occur in patients who tested positive for a bloodborne germ.

Avian flu pandemic a very real threat

A new influenza pandemic is being seen by experts as the most significant global public health emergency caused by a naturally occurring pathogen.

Molecular switch may help fight off MRSA

The discovery of a 'molecular switch' could lead to new ways of treating infections such as MRSA, and inflammatory diseases like arthritis.

Novel strategy to create a genetic vaccine against P. aeruginosa

Pseudomonas aeruginosa is a bacterium that can cause respiratory tract infections, which can be life threatening in patients who have cystic fibrosis. It is therefore important to develop a vaccine against this pathogen.

Surprising discovery about natural immunity to pneumococcus

Since 2000, U.S. infants have been routinely immunized against pneumococcal (Streptococcus pneumoniae) infection. Now, Boston researchers have made a surprising discovery about natural immunity to pneumococcus.

Scientists provide insight into the molecular mechanisms behind Listeria monocytogenes

When the bacterium Listeria monocytogenes invades the body, it commandeers its host cell's actin cytoskeleton to invade other cells. In a report published in the Journal of Biological Chemistry, a group of scientists provide insight into the molecular mechanisms behind this infection technique.

Drug-resistant bacteria on uncooked poultry products varies by commercial brand

The presence of drug-resistant, pathogenic bacteria on uncooked poultry products varies by commercial brand and is likely related to antibiotic use in production, according to researchers at the Johns Hopkins Bloomberg School of Public Health.

New immunotherapeutic approach against anthrax

The anthrax attacks in the aftermath of September 11, 2001 in the USA have illustrated the high potential of anthrax for misuse in bio-terrorism. Dissemination of anthrax by letters led to the death of 5 people and chemotherapeutic treatment of 30,000 individuals.

Naturally occurring antifungal agent in saliva kills oral pathogen responsible for most HIV-related oral infections

Oral biologists at the University at Buffalo have shown for the first time how histatin, the naturally occurring antifungal agent in saliva, kills the oral pathogen Candida albicans, the fungus responsible for most HIV-related oral infections.

Government is treating the symptoms and not fighting the causes of infectious diseases

The Microbiology Awareness Campaign gathered momentum this week at the House of Lords when scientists informed Peers and MPs that new and re-emerging infectious diseases could spell trouble if not tackled soon.

Study first to document increase risk of herpes infection due to oral sex, particularly in young women

The first clinical study to document risk of acquiring herpes simplex virus type 1 infection based on sexual activity has linked oral sex and vaginal intercourse with a demonstrably higher rate of infection, particularly in young women, researchers from the University of Pittsburgh report in the February issue of Sexually Transmitted Diseases, the journal of the American Sexually Transmitted Diseases Association.

Bacterial spread all down to chance: some strains 'just the luckyones'

Scientists have discovered that factors such as human immunity and drug resistance are less important to the success of bacterial spread than previously thought.

New filter promises clean water for millions

A handful of clay, yesterday’s coffee grounds and some cow manure are the simple ingredients that could bring clean drinking water to developing countries around the globe.

Gene transfer used to deliver antibodies to fight Anthrax

Using gene transfer technology, investigators were able to immunize mice against anthrax in just 12 hours, according to new research featured in the February 2005 issue of Molecular Therapy, the peer-reviewed scientific journal of the American Society of Gene Therapy (ASGT).

Using models to understand malaria

Malaria is one of the world's major killers. More than 500 million people live in epidemic regions and some 2 million - mostly children - die each year. And each year, drug resistance increases in the malarial parasite, Plasmodium falciparum, and the search for new treatments becomes more desperate.
