Scientists said Sunday that the Clostridium difficile epidemic from 2002 to 2006 - an outbreak of gastrointestinal illness that spanned hospitals across the globe - was caused by two closely-related strains of the bacterium and not one, as had been previously believed. Trevor Lawley of the Wellcome Trust Sanger Institute in Hinxton, England and coauthors from other institutions sequenced the genomes of C. difficile samples collected between 1985 and 2010, mainly from hospital patients. Analyzing the samples, they found the two lineages of the bacterium,which they named FQR1 and FQR2.

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.

Visitors and patients at UCLA hospitals probably won't notice what's gone missing from the chili, hamburgers and chicken dishes they order for lunch. But by putting antibiotic-free ground beef, ground beef patties and chicken breasts on the menus at the university's Ronald Reagan UCLA Medical Center and UCLA Medical Center in Santa Monica, hospital officials hope to strike a blow against so-called superbugs. Feeding antibiotics to cows, chicken and pigs is a common practice that enhances growth in the animals but also contributes to the growing problem of antibiotic resistance: when microbes evolve to become impervious to attack, making it more and more difficult for physicians to treat infections.

The U.S.-raised animals we eat consumed about 29 million pounds of antibiotics in the last year alone, according to a first-ever Food and Drug Administration accounting of antimicrobial drug use by the American livestock industry. The release of the figures -- in a little-noticed posting on the FDA's website Friday -- came in response to a 2008 law requiring the federal government to collect and disseminate antibiotic use in livestock as part of the Animal Drug User Fee Act . The Union of Concerned Scientists, which authored a 2001 report that was highly critical of the routine practice of feeding antibiotics to livestock, estimated the yearly animal consumption of antibiotics to be eight times as large as the volume of antibiotics produced for human consumption in the U.S. Mardi Mellon, director of the Union of Concerned Scientists' Food and Environment program, said the new report corroborates the 2001 findings of the group's report, titled "Hogging It.

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.
