NewsNew source of natural antibiotics hidden within our own proteins identified
A team of scientists has identified a new type of antimicrobial peptides (AMPs) found in human proteins that are capable of selectively eliminating multidrug-resistant bacteria, particularly of the gram-negative type, responsible for serious hospital acquired infections.

NewsResearchers reveal remarkable antimicrobial activity in hydrogen boride nanosheets
Hydrogen boride (HB) nanosheets represent an exciting new frontier in the search for technologies that can combat microbes in everyday settings. Researchers discovered that they exhibit excellent antibacterial, antiviral, and antifungal properties.

NewsCan gut microbes save patients from chemotherapy side effects?
Intestinal microbes that survive chemo can rid the gut of excess chemo drugs and produce a vitamin that helps to stem nausea, a new study reveals.

NewsCould nanoplastics in the environment turn E. coli into a bigger villain?
New research suggests certain nanoplastics may make foodborne pathogens more virulent. Nanoplastics with positively charged surfaces were more likely to cause physiological stress in E. coli O157:H7, making them pump out more Shiga-like toxin.

NewsScientists evaluate in-vitro activity of ceftazidime-avibactam against carbapenem-resistant gram-negative bacteria
Scientists explored the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria collected at the outpatient, emergency, and inpatient departments of the Indus Hospital, Karachi.

NewsActivating ‘jumping genes’ speeds up bacterial evolution from decades to weeks
Scientists have developed a system to control and accelerate the evolution of changes in the bacterial genome structure, targeting small ‘jumping genes’, or DNA sequences known as insertion sequences.
-
NewsSlow-growing bacteria respond more sensitively to their environment
A new study reveals that the responsiveness of bacterial cells to environmental stimuli is directly linked to their growth rate: the slower cells grow, the more sensitively they respond. This increased sensitivity can give the cells a crucial survival advantage.

NewsBiological patterns: Stability through protein reservoirs
Biophysicists have figured out how bacteria form robust patterns despite changing environmental conditions and fluctuating protein concentrations.

NewsBacteria deployed as living test tubes to study human gene mutations
Bioengineers have developed a new simple approach to rapidly check on human gene changes and also screen chemicals as potential drugs by turning everyday bacteria into living test tubes.

NewsBacteria use ancient war trick to outsmart viruses – and it could help us fight superbugs
Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. They’ve named it Kongming after the Chinese military strategist who famously used enemy weapons to defeat his foes.

NewsGlycan-coated magnets: A game-changer for safer food supply chains
A new method using glycan-coated magnetic nanoparticles (gMNPs) is poised to change the way we detect foodborne pathogens like Escherichia coli and Salmonella in complex food matrices such as melons, lettuce, and raw chicken.

NewsNovel breath test shows promise for diagnosing and monitoring bacterial infections
A new, non-invasive breath test has emerged as a potential breakthrough for rapidly diagnosing bacterial infections and tracking treatment effectiveness.

NewsSpinning into the future: fidget spinner revolutionizes bacterial detection
The plasmonic fidget spinner (P-FS) integrates nanoplasmonic technology with surface-enhanced Raman spectroscopy (SERS) to provide ultra-fast and precise bacterial identification.

NewsScientists reveal new bacterial toxin that damages the gut
Scientistshave discovered how a diarrhoea-causing strain of bacteria uses ’molecular scissors’ to cut open and destroy gut cells, leading to severe illness and sometimes death.
-
NewsAntibiotic resistance among key bacterial species plateaus over time
Scientists studying eight key bacterial species found that while antibiotic resistance initially rises in response to antibiotic use, it does not rise indefinitely. Instead, resistance rates reached an equilibrium over the 20-year period in most species.

NewsPrecision medicine could be possible in the fight against antibiotic resistance
The first-of-its-kind in-depth bacterial evolutionary map could pave the way for the development of precision treatments for certain antibiotic-resistant infections, such as urinary tract infections.

NewsMicroalgae and bacteria team up to convert CO2 into useful products
Most methods of genetically modifying the bacterium Escherichia coli and other microbes to convert carbon dioxide into useful biological products require additional carbon sources. A new study overcomes this limitation by combining the photosynthetic finesse of a single-celled algae with the production capabilities of the bacteria E. coli.

NewsBfR organises three-day conference on food microbiology
The German Federal Institute for Risk Assessment, the German Society for Microbiology and Hygiene (DGHM) and the Association for General and Applied Microbiology (VAAM) are inviting researchers to the 19th Food Microbiology Conference in Berlin from 1 to 3 April.

NewsScientists develop eco-friendly, nylon-like plastic using microorganisms
Scientists have developed microbial strains through systems metabolic engineering to produce various eco-friendly, bio-based poly(ester amide)s from glucose derived from biomass sources such as waste wood and weeds.

NewsStudy uncovers the core principles of low-resistance antibiotics
Researchers have demonstrated that a dual-target approach, combining membrane disruption with an additional critical cellular pathway, significantly prevents the development of resistance in bacteria.
