Scientists said on Thursday that a gene which makes bugs highly resistant to almost all known antibiotics has been found in water supplies in New Delhi used by local people for drinking, washing and cooking. The researchers said the NDM 1 gene has spread germs that cause cholera and dysentery, and is circulating freely in other bacteria in the Indian city capital of 14 million people. "The inhabitants of New Delhi are continually being exposed to multidrug-resistant and NDM 1-positive...

Research published in the journal GENETICS suggests ways to increase the cost of antibiotic resistance and prolong the usefulness of antibiotics A team of scientists from the University of Oxford, U.K. have taken lessons from Adam Smith and Charles Darwin to devise a new strategy that could one day slow, possibly even prevent, the spread of drug-resistant bacteria. In a new research report published in the March 2011 issue of GENETICS (http://www.genetics.org), the scientists show that...

Measuring the mechanical strength of cancer cell mucus layers provides clues about better ways to treat cancer, and also suggests why some cancer cells are more resistant to drugs than others, according to Kai-tak Wan, associate professor of engineering at Northeastern University, Boston, Mass. According to Wan, healthy tissues naturally secrete mucus to protect against infection. Cancer cells, however, produce far more mucus than healthy cells. Mucus consists of protein "stalks" attached to...

Infections are among the most frequent complications of a stay in hospital and raise the complication and mortality rates. Calculations based on data from the Hospital Infection Surveillance System (Krankenhaus-Infektions-Surveillance-System, KISS) showed an incidence of almost 60 000 newly acquired infections per year in intensive care units in Germany. This is the conclusion reached by Christine Geffers and her coauthor in the current issue of Deutsches Óžrzteblatt...

A School of Science at Indiana University-Purdue University Indianapolis biophysicist has developed a new method to identify communication pathways connecting distant regions within proteins. With this tool, Andrew J. Rader, Ph.D., assistant professor of physics, has identified a mechanism for cooperative behavior within an entire molecule, a finding that suggests that in the future it may be possible to design drugs that target anywhere along the length of a molecule's communication pathway...

Genetic resistance to antibiotics is not the only trick bacteria use to resist eradication"“ they also have a second defence strategy known as persistence that can kick in. Researchers reporting in the Journal of Medical Microbiology have now demonstrated for the first time that interplay occurs between the two mechanisms to aid bacterial survival. The findings could lead to novel, effective approaches to treat multi-drug resistant (MDR) infections. 'Persister' bacterial cells are...

Cold plasma jets could be a safe, effective alternative to antibiotics to treat multi-drug resistant infections, says a study published in the January issue of the Journal of Medical Microbiology on 15 December. The team of Russian and German researchers showed that a ten-minute treatment with low-temperature plasma was not only able to kill drug-resistant bacteria causing wound infections in rats but also increased the rate of wound healing. The findings suggest that cold plasmas might be a...

A new molecular simulation technique developed by researchers at RIKEN and Kyoto University has confirmed for the first time the function of the transporter protein AcrB in E. coli multidrug resistance. The result marks a key step in efforts to combat antibiotic resistance, demonstrating the power of computer simulation as an essential tool for basic research. (PRWeb UK) November 19, 2010 A new molecular simulation technique developed by researchers at RIKEN and Kyoto University has...

A key enzyme in Mycobacterium tuberculosis that enables the microbe to reproduce rapidly could be a golden target for new drugs against tuberculosis (TB), according to a study published in Microbiology on 17 November. The human equivalent of this enzyme has been targeted in some cancer treatments as well as in immunosuppressive chemotherapies. Scientists at the University of Birmingham have now shown that inhibiting the same enzyme in M. tuberculosis effectively kills the bacterial cells. The...

Agency partners with CDC to kick off Get Smart about Antibiotics Week SILVER SPRING, Md., Nov. 15, 2010 /PRNewswire-USNewswire/ -- This year, millions of antibiotics will be prescribed. Antibiotics can be used to treat bacterial infections; however, they are commonly over-prescribed. Patients sometimes ask their health care professional to prescribe antibiotic drugs for viral infections, like the common cold, despite the fact that they will not work and may lead to potentially harmful side...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
