Photodynamic therapy may be an effective treatment for infections of the oral cavity

Researchers found that the bacteria S. mutans, as well as fungal organisms of the genus Candida, cultured from HIV patients, were highly susceptible to killing with minimal doses of PDT, both in laboratory dishes and on biofilms grown on denture material.

Link between childhood exposure to tobacco smoke and Streptococcus pneumoniae

Many of the medical risks associated with smoking, such as cancer, emphysema and heart attacks, are well-known to physicians and the general public.

University of Michigan researchers target stubborn gram-negative bacteria

Ronald Woodard's team set out looking for a way to kill a stubborn type of bacteria and they succeeded - but not in the way he expected.

Details of protein-cleaving complex key to microbe's survival may improve drug design

With the hope of designing more effective treatments for tuberculosis (TB), scientists from the U.S. Department of Energy's Brookhaven National Laboratory and collaborating institutions have published the first detailed reports on the biochemistry and structure of a protein-cleaving complex that is essential to the TB bacterium's survival.

Clinical implication of routine stone culture in percutaneous nephrolithotomy - A prospective study

If you have a patient with a staghorn stone and the preoperative urine culture is sterile, does that mean that the stone is likewise sterile? The answer is No.

Researchers gain key insights into how different types of infection-fighting T-cells survive

T-cells, or lymphocytes, are the body's natural defense mechanism against infection, directly attacking foreign bodies such as bacteria and viruses.

Mutant genes trigger AMD but may lighten the way to new treatments

According to new research in the U.S., the most common form of blindness in the elderly, age-related macular degeneration (AMD), can be attributed to just two genes which trigger the condition.

Interferon-producing killer dendritic cell speeds up immune reactions and fights cancer

A mouse immune cell that plays dual roles as both assassin and messenger, normally the job of two separate cells, has been discovered by an international team of researchers from the United States and France.

Global evolutionary map reveals new insights into our last common ancestor

In 1870 the German scientist Ernst Haeckel mapped the evolutionary relationships of plants and animals in the first 'tree of life'.

Genome signature tagging used to quickly identify and distinguish between pathogens and harmless microbes

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new, high-throughput technique for identifying the many species of microorganisms living in an unknown "microbial community."

Photodynamic therapy lighting the way for medical treatments

For the millions of people who suffer from acne, sun damage or even worse, skin cancer, there is a light of hope - photodynamic therapy or PDT.

Reaction to DTaP vaccine finds no help from ibuprofen, acetaminophen

A red splotch forms where most preschoolers get their fifth, and last, shot of the acellular diphtheria-tetanus-pertussis (DTaP) vaccine, and it can last a few days.

Defective apoptosis of dendritic cells can be a critical component of autoimmune diseases

The failure of programming that sparks the death of dendritic cells - those that activate the immune system - can initiate autoimmune disease, said researchers from Baylor College of Medicine in a report that appears in the current issue of the journal Science.

Stress affects male rats more than female rats

A new study reinforces the growing body of evidence on health disparities between men and women and may possibly shed light on why socially isolated men are more vulnerable to disease and death than isolated women.

Is persistent bacterial infection good for your health?

Bacteria are bad. Mothers and doctors, not to mention the cleaning product industry, repeatedly warn of their dangers. But a Stanford University School of Medicine microbiologist is raising the intriguing idea that persistent bacterial and viral infections have benefits.

New generation gold-based drugs for treating rheumatoid arthritis

Gold compounds have been used for the treatment of rheumatoid arthritis and other autoimmune diseases for more than 75 years, but until now, how the metals work has been a mystery.

Viagra could cure Crohn's disease

Crohn's disease is a chronic inflammatory bowel disorder which causes ulcerations in the gut and can make digesting food painful.

Common practice of prescribing H2 blockers to treat acid reflux in premature infants should be discontinued

Researchers in an NIH network have found that premature infants given a common class of non-prescription drugs used to treat acid reflux are slightly more likely to develop a potentially fatal bowel disorder than are infants who are not treated with the drugs

Research points to a novel approach to treating serious Strep infections

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered that so-called flesh-eating "Strep" bacteria use a specific enzyme to break free of the body's immune system, a finding which could potentially lead to new treatments for serious infections in human patients.

24 Feb 2006

Why some infectious diseases are limited to small outbreaks and others become full-blown epidemics

In an important study forthcoming in the March 2006 issue of the American Naturalist, biologists from Yale University, University of Florida, and Dartmouth University explore the dynamics of pathogen survival and shed new light on a longstanding mystery
