Susceptibility to anthrax toxin is a heritable genetic trait that may vary tremendously among individuals, according to a new study by researchers at the Stanford University School of Medicine. Among 234 people studied, the cells of three people were virtually insensitive to the toxin, while the cells of some people were hundreds of times more sensitive than those of others. The findings may have important implications for national security, as people known to be more resistant to anthrax...

Repeated use of an antibiotic that is considered generally benign, because users seldom incur obvious side effects, induces cumulative and persistent changes in the composition of the beneficial microbial species inhabiting the human gut, researchers at the Stanford University School of Medicine have found. By a conservative estimate, something like 1,000 different varieties of microbes coexist harmoniously within a typical healthy person's gut, said David Relman, MD, professor of medicine...

By LAURAN NEERGAARD WASHINGTON - Infections may play a bigger role in premature birth than doctors have thought, says a new study that found almost one in seven women in preterm labor harbored bacteria or fungi in their amniotic fluid. It's a small study, and it doesn't prove that the germs triggered the early labor. But Monday's research used specialized molecular testing to uncover microbes that ordinary methods miss, and thus uncovered more women with simmering infections than...

Previously unrecognized and unidentified infections of amniotic fluid may be a significant cause of premature birth, according to researchers at the Stanford University School of Medicine. An analysis of amniotic fluid from women in preterm labor indicated that 15 percent of the fluid samples harbored bacteria or fungi -- an increase of 50 percent over previous estimates. The heavier the burden of infection, the more likely the women were to deliver younger, sicker infants. "If we...
