New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.

Link between, bacteria, cancer explored with funding from American Cancer Society

The role of bacteria in the development of colorectal cancer is coming under scrutiny at the University of Rochester Medical Center, thanks to an $840,000 research award from the American Cancer Society.

Universal vaccination associated with decreased Canadian cases of most deadly strain of meningitis

Universal childhood vaccination against meningococcal C appears to reduce Canadian incidence of the most deadly strain of bacterial meningitis, reports new research published in the March issue of The Pediatric Infectious Disease Journal.

Instant immunity through chemically programmable vaccination and covalent self-assembly

The experiments, thus far performed only in mice, appear to overcome a major drawback of vaccinations - the lag time of days, or even weeks, that it normally takes for immunity to build against a pathogen.

Newly discovered protein points to new treatment for serious lung disease

The discovery by Uppsala University researchers of a previously unknown protein in the cells of the lower air ways brings new potential for early diagnosis of a serious lung disease.

Scientists debug Clostridium difficile

An international team of scientists, led by Monash University researchers, has uncovered the workings of a superbug that kills elderly hospital patients worldwide - a discovery that has the potential to save lives and health care systems billions of dollars each year.

Help for children with rheumatic heart disease

These bacteria carry a special protein sequence, the so-called PARF motif, on their surface.

Doctors call for change in how non-active tuberculosis in immigrant children treated

New guidelines proposed in the March 2009 issue of the journal Pediatrics by researchers from the Indiana University School of Medicine and Riley Hospital for Children may have a major impact on how pediatricians and family physicians treat non-active tuberculosis (TB) in children who are immigrants, internationally adopted or refugees.

Bacteria-killing enzyme cures mice with fatal pneumonia

Before the advent of antibiotics, pneumonia claimed so many lives - and was so feared - that it was called the "captain of the ship of death."

Lab tests show meropenem and clavulanate combination effective against drug-resistant TB bacteria

WHAT: In a finding that could soon help people infected with untreatable, highly drug-resistant tuberculosis (TB), scientists have shown that two FDA-approved drugs work in tandem to kill laboratory-grown strains of Mycobacterium tuberculosis (Mtb), the bacterium that causes TB.

Drug combo shows potential for treating extensively drug resistant tuberculosis

A combination of two FDA-approved drugs, already approved for fighting other bacterial infections, shows potential for treating extensively drug resistant tuberculosis (XDR-TB), the most deadly form of the infection.

Zoologists search sea for drugs of the future

No matter how sophisticated modern medicine becomes, common ailments like fungal infections can outrun the best of the world's antibiotics.

Immune system found to be more versatile than previously thought

By studying how mice fight off infection by intestinal worms - a condition that affects more than 1 billion people worldwide - scientists have discovered that the immune system is more versatile than has long been thought.

Discovery of gene that modifies severity of cystic fibrosis lung disease

Researchers have discovered a gene that modifies the severity of lung disease in people with the lethal genetic condition, cystic fibrosis, pointing to possible new targets for treatment, according to a new study in Nature.

Johns Hopkins safety team works to eliminate bloodstream infections in the nation and the world

A widely heralded Johns Hopkins safety initiative to reduce bloodstream infections in intensive care units (ICUs) was implemented in 30 states starting Feb. 1 and could save an estimated $3 billion dollars and 30,000 lives annually.

Researchers block immune cell rush behind deadly sepsis

Researchers have found a way to block the ability of white blood cells to sprint toward the sites of infection when such speed worsens the damage done by sepsis, the often fatal, whole-body bacterial infection, according to a study published today in the journal Blood.

Scientists manipulate bacteria into generating their own vaccine

Scientists have developed a way to manipulate bacteria so they will grow mutant sugar molecules on their cell surfaces that could be used against them as the key component in potent vaccines.

Microfluidic device mimics tumor microenvironment, helps drug discovery

One of the challenges that cancer researchers face in designing new antitumor agents is that of predicting how drug molecules will behave in the complex microenvironment that surrounds a tumor. In particular, tumors create all sorts of chemical and physical barriers that limit how much drug is able to enter a tumor, let alone reach cells deep within a tumor.

Meningitis bacteria dress up as human cells to evade our immune system

The way in which bacteria that cause bacterial meningitis mimic human cells to evade the body's innate immune system has been revealed by researchers at the University of Oxford and Imperial College London.
