Antibiotics are known to attack different vital processes in bacteria. But a study published in Cell1 today has revealed that three major classes of unrelated drugs use the same ultimate weapon to finish off the infectious critters. All of them force...
  • Bid to Create Super-Antibiotics

    09/07/2007 7:56:40 AM PDT · by Froufrou · 4 replies · 263+ views ^ | 09/06/07 | Unknown
    Research into the way antibiotics work could make them more effective weapons in the battle against bacteria. Researchers have learned that all three major classes of antibiotics kill bugs by boosting levels of free radicals, destructive molecules which damage DNA and cell membranes. The new findings could aid the development of new anti-bacterial drugs, and help scientists overcome resistance to existing antibiotics. One way bacteria become drug resistant appears to be through their in-built DNA repair mechanism, which kicks in after exposure to free radicals. "Our findings suggest that if you could shut off the bacteria's repair response, you might...

    In Mexico, pharmacies don't require a prescription for antibiotics. They are sold like most cold remedies here are, over the counter. It has come to the attention of the Bradley County District Attorney's office that this practice has found its way here. District Attorney General Steve Bebb has issued a warning for stores that cater to hispanic customers that the stocking and sale of antibiotics in the United States by anyone but a licensed pharmacologist filling a legal prescription will not be tolerated. The warning came in the form of a bi-lingual notice that was distributed to law enforcement agencies...
  • Antibiotic Use in First Year May Increase Asthma Risk

    The use of antibiotics in the first year of life is associated with an increased risk for asthma at age 7, a new study has found, and the reason may be that antibiotics destroy not only disease-causing microbes, but also those that are helpful to the developing immune system. Antibiotic use had a greater impact on children who would otherwise be considered at lower risk — children who lived in rural areas and those whose mothers did not have asthma — than on those who were already at increased risk because of an urban environment or genetic predisposition. Studies of...

    Associated Press NEW YORK -- NEW YORK Tyson Foods will no longer use antibiotics to raise chicken that is sold fresh in stores and will launch a $70 million advertising campaign to tout the shift, the nation's largest meat producer said Tuesday. The company said fresh chicken raised without antibiotics was shipped to stores Monday and will be sold beginning later this week in packaging that emphasizes that there are no artificial ingredients. "We're providing mainstream consumers with products they want," Tyson Chief Executive Richard L. Bond said at a news conference. Consumers will have to pay slightly more for...

    The rates of drug-resistant gonorrhea in the United States have increased so greatly in the last five years that doctors should now treat the infection with a different class of antibiotics, the last line of defense for the sexually transmitted disease, officials said yesterday. The percentage of drug-resistant gonorrhea cases among heterosexual men jumped, to 6.7 percent in 2006 compared with 0.6 percent in 2001, officials from the Centers for Disease Control and Prevention said. Standard monitoring of gonorrhea cases is conducted among men who go to S.T.D. clinics. New data from such sites in 26 cities show that rates...

But researchers now say that such ineffectual mixes could be used in the campaign against resistance to the drugs. The counterintuitive conclusion comes from the observation — so far seen only in the lab — that less-effective drug mixes allow bacteria that are sensitive to drugs to out-compete those that are resistant them....

    Tie ban for doctors to stop spread of MRSA By Alex Berry Last Updated: 2:35am GMT 18/12/2006 Doctors have been ordered to ditch their ties over fears they are spreading the deadly hospital superbug MRSA. An NHS trust has also told all its staff involved in direct patient care not to wear jewellery, wrist watches, scarves or any "superfluous clothing". Even consultants have been warned that being smartly-dressed when giving patients bad news could present an infection risk. The move, by Brighton and Sussex University Hospitals NHS Trust, follows a report by the British Medical Association calling for doctors to...

    About 1.7 million people die from TB globally each year A "virtually untreatable" form of TB has emerged, according to the World Health Organization (WHO). Extreme drug resistant TB (XDR TB) has been seen worldwide, including in the US, Eastern Europe and Africa, although Western Europe has had no cases. Dr Paul Nunn, from the WHO, said a failure to correctly implement treatment strategies was to blame. TB experts have convened in Johannesburg, South Africa, to discuss how to address the problem. TB presently causes about 1.7 million deaths a year worldwide, but researchers are worried about the emergence of...

    In April 2005, Sara Stephan, a 13-year old in Charleroi, Pa., developed what looked like a pimple on her cheek. A blemish on a teenager is not exactly cause for alarm, but her mother, Carla Stephan, became concerned when it started to spread and swell. “Her whole cheek got big and red,” she said. Next, a similar lesion above Sara’s eye. Then, she got one the size of a softball on her buttock, and several more on her thighs. Tests showed that Sara had a particularly persistent and sometimes deadly bacterial infection known as methicillin-resistant staphylococcus aureus, often abbreviated as...

    Health Department says it did not give antibiotics to an 18-year-old woman who later died of meningococcal disease because it was "following national guidelines". The department's director-general, Robyn Kruk, announced an external review yesterday into the handling of the case of Jehan Nassif, of Yagoona, who died on Friday morning. Ms Nassif died less than three days after a visit to Bankstown Hospital to see her boyfriend's cousin, Elias Khouzame, who had the disease. Ms Nassif's boyfriend, George Khouzame, 19, had caught a Gulf Air flight home on Monday with Elias and two other relatives from a holiday in Greece....

    It begins as microscopic bacteria that invades the intestine with the potential to kill in extreme cases, or cause severe bouts of diarrhea in other instances. Probably a hundred cases have occurred in the past year in the Antelope Valley, though most of those stricken with Clostridium difficile survived, according to Dr. Michael Cohen, an infectious diseases specialist in Lancaster who tends to patients at Antelope Valley and Lancaster Community hospitals. "We've had cases at both hospitals," Cohen said. "Cases have been documented nationwide. At least three patients in Antelope Valley died." Deaths usually result from one of two conditions:...
  • Antibiotics abridged - Unnecessarily long prescriptions may fuel drug resistance.

    Cutting the length of time that patients take certain antibiotics could help to tackle the rise in drug resistance. So say the authors of a study showing that just three days' worth of drugs can fight pneumonia just as well as a longer treatment. Many antibiotics are prescribed for a week, ten days, or more, and patients are usually told to finish the course of pills to ensure that all the infection-causing bugs are eradicated. It is widely thought that not finishing the full course of drugs may allow a few of the hardiest bugs to linger, raising the risk...

    CHICAGO - Buying organic milk these days - or organic apples, eggs, or beef - no longer has to mean an extra trip to a Whole Foods supermarket or the local co-op. Organic products now line the shelves at Safeway and Costco. And Wal-Mart - already the nation's largest organic-milk seller - says it wants to sell more organic food. Large companies including Kraft, General Mills, and Kellogg own sizable organic- and natural-food brands. Now, they are developing organic versions of their own products, too. Still, while some organic-food fans welcome its broadening appeal and availability, others worry that the...

    Darwinian evolution follows very few of the available mutational pathways to attain fitter proteins, researchers at Harvard University have found in a study of a gene whose mutant form increases bacterial resistance to a widely prescribed antibiotic by a factor of roughly 100,000. Their work indicates that of 120 harrowing, five-step mutational paths that theoretically could grant antibiotic resistance, only about 10 actually endow bacteria with a meaningful evolutionary advantage. The research is described this week in the journal Science. "Just as there are many alternate routes one might follow in driving from Boston to New York, one intrinsic property...

    ATLANTA, March 21 — Antibiotic resistance has long been an important human health problem. But now it is also showing up in a small but growing number of pets in this country, Canada and Europe, scientists and federal health officials said on Tuesday at the International Conference on Emerging Infectious Diseases here. The health officials said they did not want to sound too loud an alarm. But they said they wanted to learn more about the problem that has developed involving the bacterium Staphylococcus aureus, the most common cause of staphylococcal infections among people. The same genetic strains of S....
