Only 20% of the antibiotics sold in the U.S. are given to people who are sick with bacterial infections, such as ear and urinary tract infections and pneumonia. Most of the penicillin, tetracycline and other antibiotic drugs used in this country are given to livestock that are perfectly healthy. Farmers have been putting these medicines in animal feed since the 1950s. They say the drugs help protect herds from infectious diseases and help animals grow faster. But for at least 40 years, the U.S. Food and Drug Administration has been concerned that the widespread practice may be fueling the growth of human pathogens that are no longer vulnerable to doctors' front-line drugs.

When an HIV-infected patient walked into Dr. Daniel Berger's office with a nasty sore on his wrist, the physician suspected the culprit was a bacterium known as MRSA. The test results, however, were unexpected. Yes, this was methicillin-resistant Staphylococcus aureus, but it was unresponsive to two medications that are recommended, mainstay treatments. Berger realized the already-formidable microbe had strengthened its defenses. "I was quite concerned, needless to say," said Berger, who since that incident two years ago has treated several other patients with similar infections.

Tetracycline kills bacteria involved in a host of ailments, including periodontal disease. Now it's being further trained on gum disease--but not as an antibiotic. Tetracycline blocks the action of collagenase, an enzyme implicated in the tissue destruction of periodontal disease, say researchers at the State University of New York at Stony Brook. Collagenase breaks down collagen, the connective tissue that forms the framework for skin, bone and gum.

Researchers have solved a medical mystery that has eluded them for hundreds of years, demonstrating that an abundance of abnormal skin proteins causes the blotchy skin condition called rosacea. In a study published Sunday in the journal Nature Medicine's online edition, scientists showed that people with rosacea had too much of an incorrectly processed protein called cathelicidin. The results could aid researchers in designing an effective treatment for the disease affecting 14 million in the U.

Question: Pregnant women sometimes do get sick. Suppose a pregnant woman needs an antibiotic. Is she permitted to have it? Answer: Some antibiotics, including penicillin, appear to be safe for use during pregnancy.

I suffer from digestive upset when taking antibiotics, and I'd like to counter that with the probiotic bacteria in yogurt. Does taking antibiotics with yogurt affect absorption of antibiotics? It depends to a certain extent on the antibiotic, but many should not be taken within a few hours of yogurt or other calcium-rich foods. That includes antibiotics in the tetracycline family and drugs such as ciprofloxacin and norfloxacin, but not ofloxacin. Fruit juice fortified with calcium also can interfere with antibiotic absorption.
