Antibiotics have long been a favorite remedy to treat acne. Adults and adolescents with even mild outbreaks are sometimes treated with tetracycline or erythromycin to quickly clear blemishes. But doctors may be forced to become stingier with antibiotics. Several recent studies show that acne-causing bacteria, Propionibacterium acnes--or P. acnes--have developed strains that resist both topical and oral antibiotics.

Patterns of antibiotic overuse vary in the U.S. vary by region, with residents of some Southeastern states taking about twice as many antibiotics per capita as residents in some Western states. According to the Washington-based Center for Disease Dynamics, Economics and Policy , Kentucky, West Virginia, Tennessee, Mississippi and Louisiana were the states with the highest rates of antibiotic use in 2010. Those states had more than one antibiotic prescription per capita in 2010. The states with the lowest use of antibiotics that year were Alaska, Hawaii, California, Oregon and Washington, with just over one prescription for every two people. Overall, the rate of antibiotic prescriptions in the U.S. declined from 966 prescriptions for each 1,000 residents in 1999 to 801 in 2010.

For most people who contract Lyme disease - a bacterial infection borne by ticks - a course of antibiotics does the trick. But for some, especially those who live in areas like the Northeast U.S., where Lyme disease is particularly common, the infection comes back. That raises questions about whether the disease is recurring - a single infection leading to multiple bouts with symptoms - or if reinfection is occurring, meaning the patient is unlucky enough to have been bit again. Now a new study, published Wednesday in the New England Journal of Medicine , appears to lay the question to rest: Such patients are reinfected, and Lyme disease does not appear to recur after successful courses of antibiotics.

Researchers have concluded that a Nebraska boy's infection by salmonella bacteria resistant to a widely used pediatric antibiotic came from cattle on his farm. The report has heightened concerns of public health officials that the routine use of antibiotics by farmers to treat and promote the growth of livestock is reducing the ability of similar antibiotics to cure humans of infections.

Bacteria, which cause a wide variety of diseases in humans ranging from diarrhea to pneumonia, appear to be developing resistance to medicine's arsenal of antibiotic drugs at an alarming rate around the world. More types of bacteria are becoming resistant to antibiotics, and organisms already resistant to one drug are developing resistance to new drugs, according to a new government-sponsored study. "You have to say it's serious," said Dr. Stuart B.

In a recent study, researchers in Seattle found antibiotics highly effective in preventing persistent urinary tract infections in all but two young women they studied. Laboratory tests uncovered the apparent reason for the two exceptions. Both women harbored infection-causing bacteria in their systems that were resistant to antibiotics, making the drugs unable to kill the bacteria.

People striving to sterilize their homes and hands with anti-bacterial soaps may be fueling the development of dangerous organisms that defy known drugs, according to an authority on drug-resistant strains. Dr. Stuart Levy of Tufts University, president of the Alliance for Prudent Use of Antibiotics, said last week that the popularity of disinfectant cleaners could not come at a worse time--an era when hospitals are discharging patients earlier to complete their recoveries at home.

Estimated cases of infection with methicillin-resistant Staphylococcus aureus , or MRSA, fell more than 30% in the U.S. between 2005 and 2011, suggesting that heightened efforts to combat the infections in hospitals had made a difference, researchers wrote Monday in the online edition of JAMA Internal Medicine. But another report, also published online in the journal, found that people who lived closest to farms had higher rates of MRSA infection than people who lived farthest from farms - reflecting ongoing concerns about antibiotic use in agriculture and its effects on human health.
