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)

Bacteria take a deadly risk to survive
Bacteria need mutations -- changes in their DNA code -- to survive under difficult circumstances. When necessary, they can even mutate at different speeds. This is shown in a recent study by the Centre of Microbial and Plant Genetics at KU Leuven (University of Leuven), Belgium. The findings open up various new avenues for research, ranging from more efficient biofuel production methods to a better treatment for bacterial infections and cancer. (2017-05-02)

Bioinspired agent kills drug-resistant bacteria
Microbial resistance to antibiotics and biocides is increasing, and our ability to effectively treat bacterial infections and contamination is under threat. Researchers have developed an antimicrobial treatment that can rapidly kill drug-resistant bacteria. These iodo-thiocyanate complexes caused rapid bacterial death in the tested strains, which included an antibiotic-resistant strain. They could kill both free-floating bacteria and those in biofilms, suggesting that they could be used for decontamination in a variety of situations. (2017-05-02)

Two presentations at the 27th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) show that repeated infection with the bacterium Clostridium difficile (C. difficile), which causes stomach upsets and diarrhoea, is linked to higher death rates, as well as having a significant impact on health services in terms of cost and hospital beds occupied. (2017-04-20)

Same but different
Bacterial populations pose an intriguing puzzle: in so-called isogenic populations, all bacteria have the same genes, but they still behave differently, for example grow at different speeds. Researchers at the Institute of Science and Technology Austria (IST Austria) now solved a part of this puzzle by studying how the bacterium Escherichia coli divides up a protein complex that detoxifies cells by pumping multiple drugs such as antibiotics out of the cell. (2017-04-20)

(2017-04-18)

Study examines effectiveness of steroid medication for sore throat
In patients with a sore throat that didn't require immediate antibiotics, a single capsule of the corticosteroid dexamethasone didn't increase the likelihood of complete symptom resolution after 24 hours, and although more patients taking the steroid reported feeling completely better after 48 hours, a role for steroids to treat sore throats in primary care is uncertain, according to a study published by JAMA. (2017-04-18)
