Dr. Brad Spellberg, an infectious disease expert at Harbor UCLA Medical Center says there is no current teatment for CRKP bacteria — and there might not be any in the future either. County health officials warn the elderly are especially at risk of CRKP infections. (Getty Images) “There’s been a complete collapse in the development of new antibiotics over the last decade…and in the next decade there isn’t going to be anything that becomes available that’s going to be able to treat these bacteria,” said Spellberg. Medical expert Dr. David Baron of Primary Caring in Malibu cautions hospital visitors that...

Prescribing antibiotics for patients with discoloured phlegm caused by acute cough has little or no effect on alleviating symptoms and recovery, a Cardiff University study has found. Acute cough is one of the common reasons why people visit their GP and accounts for a large proportion of antibiotics prescribed in the community. One of the most common questions asked by GPs to their patients is about their phlegm: "Are you coughing anything up?" or "What colour is your phlegm?" Clinicians and patients commonly believe that yellow and green phlegm production is associated with a bacterial infection, which is more likely...

New Antibiotics, Stat!The drug makers are in a bind — and public health is in danger. The development of new antibiotics has slowed to a trickle, just when we need them most. As drug-resistant bacteria are on the rampage worldwide, we find ourselves in a most precarious situation — one not unlike the pre-antibiotic era, before penicillin, when staphylococcal and pneumococcal infections were the dominant pathogens. Now MRSA (methicillin-resistant Staphylococcus aureus) kills more people than AIDS every year, and various multiple-drug-resistant organisms have appeared, leaving doctors with few therapeutic weapons for treating a number of prevalent infections. How did this...

WASHINGTON (Reuters) – Even seemingly gentle antibiotics may severely disrupt the balance of microbes living in the gut, with unforeseen health consequences, U.S. researchers reported on Monday. An intimate study of three women given ciprofloxacin showed the drug suppressed entire populations of beneficial bacteria, and at least one woman took months to recover. The study, published in the Proceedings of the National Academy of Sciences, supports the common wisdom that antibiotics can damage the "good" germs living in the body. It may also support the idea behind the development of so-called probiotic products including yogurt with live cultures of bacteria.

A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer. The finding is the strongest evidence yet that the art of making antibiotics, which officially dates to the discovery of penicillin in 1928, was common practice nearly 2,000 years ago. The research, led by Emory anthropologist George Armelagos and medicinal chemist Mark Nelson of Paratek Pharmaceuticals, Inc., is published in the American Journal of Physical Anthropology. “We tend to associate drugs that cure diseases with modern medicine,” Armelagos says. “But it’s becoming increasingly clear that this prehistoric population was...

Just 65 years ago, David Livermore's paternal grandmother died following an operation to remove her appendix. It didn't go well, but it was not the surgery that killed her. She succumbed to a series of infections that the pre-penicillin world had no drugs to treat. Welcome to the future. The era of antibiotics is coming to a close. In just a couple of generations, what once appeared to be miracle medicines have been beaten into ineffectiveness by the bacteria they were designed to knock out. Once, scientists hailed the end of infectious diseases. Now, the post-antibiotic apocalypse is within sight....

A new superbug that is resistant to even the most powerful antibiotics has entered UK hospitals, experts warn. They say bacteria which make an enzyme called NDM-1 travelled back with NHS patients who had gone abroad to countries like India and Pakistan for treatments such as cosmetic surgery. Although there have only been about 50 cases identified in the UK so far, scientists fear it will go global. Tight surveillance and new drugs are needed says Lancet Infectious Diseases. NDM-1 can exist inside different bacteria, like E.coli, and it makes them resistant to one of the most powerful groups of...

There are many that believe bikinis are the world's greatest scientific breakthroughs. Many believe that Quaaludes should be brought back. Then there is the world wide favorite, beer, wine, and thermoses. Whoopie cushions, helmets that hold two beer cans, soda cans, (strangely) flying squirrels, the Spork, and reclining chairs. Then there's toilet paper, sunglasses, the fork, air conditioner, paper, the refrigerator, the printing press, and electricity. All are lifestyle accoutrements that make living easier and more enjoyable. But in actuality, the truly brilliant discoveries transcend culture, lifestyle, and Preparation H (no matter how highly recommended). Below are listed and described...

OSLO, Norway – Aker University Hospital is a dingy place to heal. The floors are streaked and scratched. A light layer of dust coats the blood pressure monitors. A faint stench of urine and bleach wafts from a pile of soiled bedsheets dropped in a corner. Look closer, however, at a microscopic level, and this place is pristine. There is no sign of a dangerous and contagious staph infection that killed tens of thousands of patients in the most sophisticated hospitals of Europe, North America and Asia this year, soaring virtually unchecked. The reason: Norwegians stopped taking so many drugs.

US scientists are targeting an enzyme essential to bacterial metabolism in the search for new antibiotics.Michael Burkart of the University of California, San Diego, and Anton Simeonov from the National Institutes of Health, Bethesda, and coworkers have developed a high-throughput kinetic assay to screen small molecules as inhibitors of surfactin-type phosphopantetheinyl transferase (Sfp-PPTase) enzymes.Transferases are among a group of enzymes that can add and remove groups from proteins after their polypeptide backbone has been built - a process known as posttranslational modification. The enzymes are of biological and pharmaceutical interest as their inhibitors have been suggested as avenues for antibacterial,...

People are less likely to get antibiotics for respiratory infections Since the mid-1990s, doctors have written fewer antibiotic prescriptions per year for respiratory infections, a new survey shows. The drop in these prescriptions in the United States per thousand people from 1995 to 2006 is 36 percent in children under age 5 and 18 percent among persons age 5 and up, researchers report in the Aug. 19 Journal of the American Medical Association. Many respiratory infections do not typically require antibiotics, including influenza, viral pneumonia, bronchitis, laryngitis, common colds and other infections caused by viruses. Infections more deserving of antibiotics...

Australian pharmaceutical firm, Biota, has said that Phase III trials of its new influenza drug laninamivir (CS-8958) have shown that a single inhaled dose of the drug was as effective as 10 doses of Roche’s Tamiflu administered orally over a 5 day period. The drug is a second generation neuraminidase inhibitor and is based on zanamivir, the active ingredient in Relenza, which Biota sold to GlaxoSmithKline. The study was conducted by Japanese pharma firm Daiichi Sankyo, which co-owns the drug, and included 1000 patients that had confirmed, naturally acquired influenza A or B. Preclinical studies have shown laninamivir to be...

The highest resolution snapshots yet showing how bacteria adapt to survive treatment with quinolone drugs are giving drug makers an additional weapon in the fight against antibiotic resistance. Scientists at King's College London and St. George's, University of London, have shown exactly how quinolones, which are the second line of defence against diseases like pneumonia and meningitis, interact with their topoisomerase IV enzyme target. The researchers captured detailed crystal structures using high power x-rays produced at the Diamond synchrotron in the UK and its French counterpart, Soleil. From these images the team has been able to identify the amino acids that mutate...

Scientists at St. Jude Children's Research Hospital have demonstrated a more effective treatment for bacterial pneumonia following influenza. They found that the antibiotics clindamycin and azithromycin, which kill bacteria by inhibiting their protein synthesis, are more effective than a standard first-line treatment with the "beta-lactam" antibiotic ampicillin, which causes the bacteria to lyse, or burst. The finding is important because pneumonia, rather than the influenza itself, is a principal cause of death from influenza in children and the elderly. During pandemics—such as the one that may arise from avian influenza—up to 95 percent of influenza deaths are due to pneumonia....

Earlier this year, Harold and Freda Mitchell of Como, Miss., both came down with a serious stomach bug. At first, doctors did not know what was wrong, but the gastrointestinal symptoms became so severe that Mrs. Mitchell, 66, was hospitalized for two weeks. Her husband, a manufacturing supervisor, missed 20 days of work. A local doctor who had worked in a Veterans Affairs hospital recognized the signs of Clostridium difficile, a contagious and potentially deadly bacterium. Although the illness is difficult to track, health officials estimate that in the United States the bacteria cause 350,000 infections each year in hospitals...

WASHINGTON (Reuters) – A bill that would ban the nontherapeutic use of antibiotics in animals would hurt the health of livestock and poultry while compromising efforts to protect the safety of the country's food supply, the leader of the largest U.S. farm group said on Tuesday. Bob Stallman, president of the 6 million-member American Farm Bureau Federation, said in a letter to Congress that its members "carefully, judiciously and according to label instructions" use antibiotics to treat, prevent and control disease in animals. "Antibiotic use in animals does not pose a serious public health threat," said Stallman, who urged lawmakers...

For a full list of the 36 generic antibiotics offered for free by Stop & Shop, visit www.stopandshop.com/antibiotics Beginning Friday, Stop & Shop Supermarket pharmacies will offer free antibiotics to anyone with a doctor's prescription, a program the company says will help maintain the health of its customers in "a difficult economy." The director of Saint Mary's Health System's infectious disease and infection control department, however, says the program is misguided. The company, with headquarters in Quincy, Mass., has 251 stores with pharmacies in the Northeast. It announced this week it will offer a free 14-day supply for any of...

Giving antibiotics to patients in hospital intensive care units (ICUs) to prevent – rather than fight – bacterial infections may reduce the number of patient deaths, Dutch scientists report today in the New England Journal of Medicine. Despite the findings, some researchers remain skeptical whether the possible risks (most notably spurring new antibiotic resistant germs) outweigh the benefits of plying patients with antibiotics instead of using other more benign strategies such as hand-washing, isolating contagious patients and scrubbing hospitals with antiseptic cleansers.

MRSA, a drug-resistant germ, lurks in Washington hospitals, carried by patients and staff and fueled by inconsistent infection control. This stubborn germ is spreading here at an alarming rate, but no one has tracked these cases -- until now. Year after year, the number of victims climbed. But even as casualties mounted -- as the germ grew stronger and spread inside hospitals-- the toll remained hidden from the public, and hospitals ignored simple steps to control the threat. Over the past decade, the number of Washington hospital patients infected with a frightening, antibiotic-resistant germ called MRSA has skyrocketed from 141...
