Bacteria: Protein researchers decipher resistance mechanism
Worldwide, resistance to antibiotics is on the rise. In order to understand why bacteria are becoming immune to previously well-functioning drugs, scientists are penetrating ever deeper into the molecular structure of cells. A research group at Martin Luther University Halle-Wittenberg (MLU) has succeeded in isolating a membrane protein from the E. coli bacterium and shed light on its molecular structure and how it manages to rid itself of the antibiotic by forcing out the drug. (2018-10-25)

Superbug genome sequenced
The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance.

Russian scientists plot antibiotic resistance on a world map
Antibiotic resistance is a serious problem for human health. Uncontrolled antibiotic usage in agriculture and medicine makes bacteria resistant to drugs and these drugs become less effective. This means that infections that used to be curable could become lethal once again. ResistoMap is an interactive visualization of the gut resistome to different antibiotics. The map will help to identify national traits in antibiotic intake and obtain a global-scale view of their resistome. Data is openly available for any researcher to download. (2017-05-02)

Resistance genes discovered in ancestral tomato species

The phytopathologist found these same two genes, which provide resistance against a certain fungus, in several wild tomato species. (2004-10-11)

Transporting broiler chickens could spread antibiotic-resistant organisms
A study by researchers at the Johns Hopkins Bloomberg School of Public Health found increased levels of pathogenic bacteria, both susceptible and drug-resistant, on surfaces and in the air inside cars traveling behind trucks that carry broiler chickens.

Research may help rescue antibiotics' effectiveness in the face of drug-resistant bacteria
Bacteria--especially Gram-negative strains--are becoming increasingly resistant to current antibiotic drugs, and the development of new classes of antibiotics has slowed. Faced with these challenges, investigators are studying the potential of combination therapy, in which two or more drugs are used together to increase or restore the efficacy of both drugs against a resistant bacterial pathogen. Now new research indicates that such synergy may work even when bacteria become resistant to colistin, which is considered a treatment agent of last resort. (2018-08-10)

(1999-01-11)

Researchers develop new approach for vanquishing superbugs
A scientific team from Case Western Reserve University School of Medicine and Cleveland Clinic has developed a new way to identify second-line antibiotics that may be effective in killing germs already resistant to a first-line antibiotic -- potentially helping overcome antibiotic resistance. This new research provides an approach clinicians could consult when deciding which antibiotic treatment courses will be most effective for patients. (2019-01-30)

Rise in antibiotics prescribed to dental patients in England during COVID-19 lockdown
One of the unintended consequences of the COVID-19 lockdowns in England earlier this year has been a 25 per cent increase in the prescription of antibiotics by dentists, according to a new study published today in the British Dental Journal (BDJ). Prescription rates were the highest in London, with an increase of 60% for the same period and the lowest increases, less than 10%, were in the South-West of England. (2020-11-13)

War on bacteria could leave drug-resistant strains unchecked
Efforts to keep our bodies and everything we touch bacteria- free could instead promote the growth of drug-resistant strains, says a Tufts University physician who urges people to abandon their irrational fears and make peace with the beneficial bacteria surrounding us. Not only do most bacteria help keep harmful bacteria in check, they may even give a baby's immune system the exercise it needs to develop normally. (2000-07-16)

Scientists at The Scripps Research Institute (TSRI) have given new superpowers to a lifesaving antibiotic called vancomycin, an advance that could eliminate the threat of antibiotic-resistant infections for years to come. (2017-05-29)

Local adaption of tuberculosis, not human migration, spread TB resistance mutations
Migration from Europe during the colonial period drove the spread of the dominant strain of tuberculosis seen today, lineage four, a new study reports. Drug resistance to this infectious disease evolved independently in various regions multiple times, the study also suggests, with little international dissemination after independent disease evolution.
