The Most Dangerous Bacteria

New York -

Athletes with infected scrapes that won't go away. Hundreds of soldiers returning from Iraq with wound infections that don't respond to most antibiotics. Often deadly pneumonias. Ninety-thousand patients who die in hospitals every year. That's the toll in the U.S. from germs that are resistant to existing medicines.

The problem is that many common bacteria and fungi have evolved into being resistant to the drugs that have kept them at bay for a half-century. The problem is not new (see), but it is still getting worse, even as a spattering of new antibiotics and anti-fungal drugs reach the market. Now, doctors are trying to get more attention for the problem, hoping that comprehensive legislation could stimulate drug firms to put more effort into developing new antibiotics.

Today, the Infectious Diseases Society of America, an association of 8,000 infectious-disease specialists, is announcing a hit list of the six most worrisome germs doctors now face in clinical practice. The list, which includes five bacteria and one fungus, is described in the current issue of Clinical Infectious Diseases, a medical journal, and will also be unveiled as part of a press conference today. For all of these germs, the authors see very few new drugs being developed and rising rates of illness.
