Antibiotic resistance News
|
Antibiotic resistance is causing significant medical problems and while a key factor is over-prescription of antibiotic medications, there are other factors. Once factor, according to new research, could be common agricultural herbicides.

Chicago -
A new class of antibiotic has been discovered. The chemical kills bacteria by binding to ribosome. This disrupts protein synthesis, and stops the microbial cell from replicating. This is a step forward in the search for new antimicrobials.

Birmingham -
British scientists have found a connection between a significant mechanism of antibiotic resistance to the disinfectant triclosan. This chemical is found in many common domestic products.

London -
Microbiologists have managed to ‘re-engineer’ an existing antibiotic so that it can take on one of the most threatening ‘superbugs’: the genera of vancomycin-resistant enterococci.
|

Community transferred and acquired MRSA is a growing concern, especially for those admitted to hospital. One common reservoir for the antibiotic-resistant bacteria are domestic dogs. A new study reveals the extent of the problem.

Dehli -
The head of one of India's drug industry lobby groups spoke out Thursday, saying media reports linking pollution in some lakes and rivers to factories making antibiotics is wrong, insisting the drug industry is in compliance with environmental rules.

|
It seems one of the strange science stories of the week, but Australian scientists have discovered that the milk from Tasmanian Devils has antimicrobial properties, including activity against antibiotic resistant organisms.
|
|
An interesting new study, using a combination of techniques from biology to mathematics has found that overcoming antibiotic-resistant bacterial infections could be achieved by using a three-drug cocktail, or combination of antibiotics.
|
|
Yale researchers went fishing for a natural product to use in combating antibiotic-resistant pathogens and found one floating on the water of a Connecticut pond.
|
|
The U.S. Food and Drug Administration issued an import alert on Malaysian shrimp and prawns on Monday. This means that all imports of the seafood products under the alert will be detained without inspection.
|
|
A large number of the nation's top food companies and others sent a letter to Congress this week, urging lawmakers to include funding in the Fiscal Year 2017 budget for the National Action Plan for Combating Antibiotic- Resistant Bacteria.
|
|
The threat of antibiotic resistance on a global scale is real, so much so that scientists are taking a second look at a therapy that has been around for a number of years. Think viruses that have the ability to infect and fight harmful bacteria.

Aiken -
Antibiotic-resistant bacteria are becoming more common, prompting medical and health care officials, as well as the media to better educate the public in the misuse and abuse of antibiotics. However, based on a new study, it may be worse than thought.
|
|
London -
As part of the growing action against the progressive rise in antibiotic resistant bacteria, two R&D organizations are to work together with the aim of creating new antibiotics.
|
One root of antibiotic resistance is from animals to people. To assess this, the European Medicines Agency (EMA) is running a public consultation on how to assess the risks of antimicrobial resistance passing from food animals to human.
|
|
A new concern has been expressed about the presence of large numbers of antibiotics in wastewater. Here treatments to "clean up" wastewater may be modifying the antibiotics and, by doing so, triggering a rise in antibiotic resistant bacteria.
|
|
Geneva -
Despite calls to restrict the use of antibiotics, in order to stem the tide of antibiotic resistance, a new report shows that around three-quarters of the countries in the world have no plans to slow-down on antibiotic use.
|
|
Washington D.c. -
Researchers have discovered antibiotic resistance genes in the bacteria of a South American tribe never exposed to antibiotic drugs. This suggests some bacteria have always been antibiotic resistant.
|
|
A new study has shown that New York City's subway system is crowded with microbes that are resistant to two widely used antibiotics.
|
|
Tokyo -
The challenge faced by scientists in developing a new generation of antibiotics to challenge the menace of antibiotic resistant superbugs is considerable. To help with this, researchers have pinpointed the how resistance develops.
|
|
Veracruz -
Antibiotic resistance is the scourge of modern medicine. Alarmingly, even animals that live far from humans are developing resistance to antibiotics.
|
|
A new study has found that over half of farm workers who look after animals in industrial hog farms carry home hog-related bacteria in their noses. This is potentially harmful for the farm workers and their families.
|
|
Lund -
A budding discovery courtesy of research teams at Lund University in Sweeden may open the door to defeating deadly, antibiotic-resistant bacteria.
|
|
Chicago -
A new drug designed to treat tuberculosis could be the basis for a class of broad-spectrum drugs that act against various bacteria. Interestingly the drug may be capable of evading resistance.
|
|
Research presented at the 247th National Meeting of the American Chemical Society indicates that honey could offer a solution to combat antibiotic-resistance among bacteria.
|
Bacteria that are found in lower numbers are more likely to mutate, resulting in higher rates of antibiotic resistance, new research has concluded.
|
|
Tianjin -
Chinese researchers have reported that some industrial solvents may help bacteria share an antibiotic resistance gene. This means that some solvents might be leading to a rise in certain bacterial diseases.
|
|
Sacramento -
The California State Senate has advanced a bill to restrict the use of antibiotics in farm animals. Farmers have been using antibiotics for growth enhancement, but now the bill will demand that the drugs be sold by prescription for medical reasons only.
|
|
The world is facing what appears to be a cataclysm in the global health care arena. “Superbugs” - bacteria that use nature’s micro-evolutionary mechanisms to develop antibiotic resistance have become a major threat to public health.

Sacramento -
Total knee replacements are no longer a rarity. Especially in adults over age 50.
Knee and hip replacement surgeries are performed in the United States at a rate of roughly one million annually.

Focused ion beam/scanning electron microscopy (FIB/SEM) image of samples challenged with 25 μg/mL gentamicin: spaceflight (left) and Earth control (right). FIB/SEM analysis corroborated the findings on reduced cell size in space. Scale bar on axes = 500 nm. Frontiers in Microbiology
E. coli commonly grows with uniform fine turbidity as seen in the 25 μg/mL Earth control (upper image). Spaceflight samples challenged with the concentrations of gentamicin at 125 μg/mL or higher tended to aggregate. The lower image shows the spaceflight sample treated with 175 μg/mL—after its return to Earth—and the clustered cells (red box) in an otherwise visibly clear growth medium. Frontiers in Microbiology
Pamela Yeh, Elif Tekin and their UCLA colleagues plan to offer open-access software based on their work that would let other scientists choose the most effective combinations of antibiotics. UCLA
