Researchers Manipulate Demographic of Bacterial Community with Novel Electronic Technology
10/05/2022 - Using second-long electrical shocks, UC San Diego scientists were able to control the types of cells in a community of bacteria. Being able to direct the ratio of cells holds implications for...
New Tool Assesses Evolutionary Risks of Antibiotics
20/01/2022 - Countering a rising antibiotic resistance crisis, doctors now prescribe combinations of antibiotics. Yet many risks are involved with such multi-drug combinations. Scientists have developed a way to...
Trained Viruses Prove More Effective at Fighting Antibiotic Resistance
08/06/2021 - Research reveals that phage viruses that undergo special evolutionary training increase their capacity to subdue bacteria. The results provide hope for the antibiotic resistance crisis, a rising...
BioVersys Gets EIB Funds to Address Antimicrobial Resistance
15/04/2021 - Financing supports development of BioVersys’ breakthrough hospital antibiotic therapy targeting Acinetobacter baumannii
Centrient Pharmaceuticals to Acquire Astral SteriTech
18/02/2021 - Brings in-house manufacturing capabilities for high-quality sterile antibiotic powder injectable finished dosage forms with two FDA-approved production lines.
Not as simple as thought: How bacteria form membrane vesicles
04/02/2021 - Researchers have identified a novel mechanism by which bacteria form membrane vesicles, which bacteria employ to communicate with each other or to defend themselves against antibiotics. By studying...
Research establishes antibiotic potential for cannabis molecule
04/02/2021 - The main nonpsychoactive component of cannabis has been shown to kill the bacteria responsible for gonorrhoea, meningitis and legionnaires disease, which could lead to the first new class of...
Scientists identify nutrient that helps prevent bacterial infection
04/02/2021 - Scientists studying the body's natural defenses against bacterial infection have identified a nutrient -- taurine -- that helps the gut recall prior infections and kill invading bacteria, such...
By changing their shape, some bacteria can grow more resilient to antibiotics
04/02/2021 - Scientists describe how glutamate signals are transmitted across synapses to turn on the switch for synapatic plasticity, the ability of synapses to strengthen or weaken over time in response to...
By changing their shape, some bacteria can grow more resilient to antibiotics
04/02/2021 - New research demonstrates how certain types of bacteria can adapt to long-term exposure to antibiotics by changing their shape.
Message in a bottle: Info-rich bubbles respond to antibiotics
04/02/2021 - Researchers describe the effects of antibiotics on membrane vesicles, demonstrating that such drugs actively modify the properties of vesicle transport. Under the influence of antibiotics, MVs were...
Antibiotic resistance may spread even more easily than expected
04/02/2021 - Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research shows that one reason could be significant genetic transfer between...
Unlocking 'the shape of water' in mechanisms of antibiotic resistance
04/02/2021 - Researchers captured and comparted hi-res images of ribosome structures from sensitive and resistant bacteria and report that a water molecule needed for antibiotic binding was not present in the...
Antibiotic resistance from random DNA sequences
19/01/2021 - An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, researchers have shown how new genes that produce resistance can arise from...
