Patients in U.S. hospitals are increasingly at risk of becoming infected with bacteria that resist treatment with antibiotics. But a new government survey has found that many hospital and clinic laboratories aren't routinely performing tests to identify some of the most dangerous drug-resistant strains. Earlier this month, the federal Centers for Disease Control and Prevention reported the fourth confirmed U.S.

The middle-aged woman was desperately ill. Brought by an anxious daughter to the emergency room at St. Joseph Medical Center in Burbank, she was nearly in a coma, her brain swelling with meningitis. Doctors swiftly put her on two antibiotics that for years have been highly effective against the disease. But she failed to improve, and lab tests showed she had a form of meningitis that resists both drugs.

At least one in every four San Franciscans newly infected with HIV, the virus that causes AIDS, contracts a form that is resistant to one or more of the commonly used AIDS drugs, researchers said here Saturday. As a result of this resistance, it takes at least three times as long to bring these infections under control, and more complicated drug regimens are often required, said Dr. Frederick M. Hecht of UC San Francisco.

The young Army medic would not stop bleeding. He had been put on a powerful regimen of antibiotics by doctors aboard the hospital ship Comfort in the Persian Gulf. But something was wrong. He was in shock and bleeding from small pricks where nurses had placed intravenous lines. Red, swollen tissue from an active bacterial infection was expanding around his abdominal wound. His immune system was in overdrive. How odd, thought Dr. Kyle Petersen, an infectious disease specialist.

AVOIDING the use of antibiotics in food animals appears to reduce drug resistance in humans, according to a study published online last week in the journal Clinical Infectious Diseases. The study involved the use of antibiotics called fluoroquinolones in Australian poultry. Australia restricts use of the antibiotics in animal husbandry because the practice is thought to contribute to drug resistance in people who contract bacterial infections from eating contaminated food.

WASHINGTON - Although malaria deaths have fallen worldwide over the last decade, health leaders warned Wednesday of a small but rising threat in parts of Southeast Asia, where anti-malaria drug resistance is confounding experts. Four countries - Cambodia, Myanmar, Thailand and Vietnam - make up an "epicenter to malarial drug resistance," said Robert Newman, the director of the World Health Organization's Global Malaria Program. Researchers have found that people in the Southeast Asia region have surprisingly high rates of resistance to artemisinin-based combination therapies, which are considered the best ways to treat the most deadly of the four types of parasites that cause malaria in humans.

About half of all adults being treated for HIV infection in the United States have strains of the virus that are resistant to some of the standard drug therapies, according to a study released Tuesday. The study is the first large-scale national survey to reveal the drug resistance. Previous drug-resistance research, physicians said, focused only on smaller groups of patients. "This is very discouraging," said Dr. Samuel Bozette of the San Diego VA Medical Center, a co-leader of the study.

Acnemedications and treatments fill drug store shelves, but some acne sufferers may have a tough time discerning which are the best to use. A paper published online in the journal the Lancet finds that certain studies on acne remedies are few and far between. In a seminar in the journal researchers from the U.S. and the U.K. reviewed the current slate of treatments available, including topical treatments such as benzoyl peroxide, retinoids and topical antibiotics, and oral treatments such as antibiotics, contraceptives and isotretinoin (the last typically used to treat severe cases of acne)

Resistance to anti-flu drugs has risen by 12% worldwide in the last decade, scientists said Thursday in a finding that could pose problems for health officials trying to avert a pandemic. Researchers at the federal Centers for Disease Control and Prevention in Atlanta found resistance to a class of drugs used to treat influenza for more than 30 years rose from 0.4% in 1994-95 to 12.3% by 2004. In some countries in Asia, drug resistance exceeded 70%.

Flu researchers Yoshihiro Kawaoka and Ron Fouchier found themselves in the middle of a firestorm when, in 2011, they reported how, in separate experiments, they had created mutant strains of the H5N1 bird flu that were able to pass easily between ferrets -- mammals often studied to understand how flu passes between people. On Wednesday, in a letter published in two leading scientific journals, the virologists and 22 coauthors explained why they are now planning to conduct similar experiments with another deadly bird flu: H7N9, which is circulating in China and has thus far killed 43 of the more than 130 people known to have been infected with it. "To fully assess the potential risk associated with these novel viruses, there is a need for further research," they wrote in the journals Science and Nature . Scientists are concerned about H7N9 flu for a variety of reasons. So far, H7N9 hasn't been as deadly as H5N1, which as of early July had killed 377 people, according to the World Health Organization (nearly 60% of the known cases.)
