Multidrug-Resistant Tuberculosis - Update
The World Health Organization (WHO) has ongoing programs to improve and monitor tuberculosis (TB). The WHO's 2011 report on global TB control provides the most comprehensive information ever collected on the problems and issues of disease, as well as deaths caused by TB and multidrug-resistant TB (i.e. disease marked by in vitro resistance to at least isoniazid and rifampicin)...

Averting Drug Resistance
Bacterial resistance to antibiotics is growing exponentially, contributing to an estimated 99,000 deaths from hospital-associated infections in the U.S. annually, according to the Centers for Disease Control and Prevention. One reason that this is happening is that drug resistant proteins are transporting "good" antibiotics, or inhibitors, out of the cells, leaving them to mutate...

Shedding New Light On The Way Superbugs Such As MRSA Are Able To Become Resistant To Treatment With Antibiotics
Scientists have shed new light on the way superbugs such as MRSA are able to become resistant to treatment with antibiotics. Researchers have mapped the complex molecular structure of an enzyme found in many bacteria. These molecules - known as restriction enzymes - control the speed at which bacteria can acquire resistance to drugs and eventually become superbugs...

Manuka Honey Could Be The Answer For Treating And Preventing Wound Infections
Manuka honey could help clear chronic wound infections and even prevent them from developing in the first place, according to a new study published in Microbiology. The findings provide further evidence for the clinical use of manuka honey to treat bacterial infections in the face of growing antibiotic resistance...

MRSA, In Pork Products
According to a study by the University of Iowa College of Public Health and the Institute for Agriculture and Trade Policy, the prevalence of methicillin-resistant Staphylococcus aureus bacteria (MRSA) in retail pork products in the U.S. is higher than researchers originally thought...

Retail Meat Products Found To Contain High Levels Of MRSA Bacteria
Retail pork products in the United States have a higher prevalence of methicillin-resistant Staphylococcus aureus bacteria (MRSA) than previously identified, according to new research by the University of Iowa College of Public Health and the Institute for Agriculture and Trade Policy...

A Cause Of Resistance To Colon Cancer Treatment Identified
Doctors and researchers of Hospital del Mar and its research institute, the IMIM, have lead a study describing a new pharmacological resistance to cancer. This new mechanism is a mutation in an oncogene called EGFR (epidermal growth factor receptor) causing resistance to treatment using a drug called cetuximab, a monoclonal antibody which specifically attacks the EGFR...

Use Of Antimicrobial Scrubs May Reduce Bacterial Burden On Health Care Worker Apparel
The use of antimicrobial impregnated scrubs combined with good hand hygiene is effective in reducing the burden of Methicillin-Resistant Staphylococcus Aureus (MRSA) on health care workers' apparel and may potentially play a role in decreasing the risk of MRSA transmission to patients, according to a new study from Virginia Commonwealth University researchers...

Mechanism Of Lung-Cancer Drug Resistance Revealed By Study
New research published in Nature Medicine indicates that targeted drugs such as gefitinib might more effectively treat non-small cell lung cancer if they could be combined with agents that block certain microRNAs. The study was led by investigators with the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J...

New Insights Into Antibiotics And Pig Feeds
Antibiotics in pig feed increased the number of antibiotic resistant genes in gastrointestinal microbes in pigs, according to a study conducted by Michigan State University and the U.S. Department of Agriculture's Agricultural Research Service...

Detecting Staph Infections With Mass Spectrometry
Researchers have designed a new laboratory test that can quickly identify the bacterium that causes Staphylococcus aureus infections. The findings have been published in the January issue of the journal Molecular and Cellular Proteomics...

Untreatable Tuberculosis Reported In India
Experts have long feared the eventual arrival of a completely drug-resistant TB (tuberculosis) - a hospital in India has reported the nation's first cases of a type of tuberculosis for which there are no effective drugs, making the TB virtually untreatable. Other untreatable TBs have emerged over the last nine years; there have been reported cases in Iran and Italy...

UGA Scientists 'Hijack' Bacterial Immune System
The knowledge that bacteria possess adaptable immune systems that protect them from individual viruses and other foreign invaders is relatively new to science, and researchers across the globe are working to learn how these systems function and to apply that knowledge in industry and medicine...

"Stay Away Unless Absolutely Essential", UK Hospital Urges People
In order to help stop sickness bugs spreading this winter, staff at Southampton's teaching hospitals are advising members of the general public to avoid the hospitals unless their visit is "absolutely essential." Currently, seven wards are not taking in new patients at Southampton General Hospital in order to prevent gastroenteritis viruses from spreading - resulting in a loss of 30 beds...

MRSA Post Tympanostomy Tube Placement Not Linked To Further Complications
According to an investigation published in the December issue of Archives of Otolaryngology - Head & Neck Surgery, researchers have discovered that ear discharge and drainage (otorrhea) caused by methicillin-resistant Staphylococcus aureus (MRSA) after ear tube placement in children is not linked to an increased risk of needing further surgery or other complications, in compari...
