NewsEngineered bacteria track down tumours, then signal the immune cells
Researchers have created a ’bacterial suicide squad’ that targets tumours, attracting the host’s own immune cells to the cancer to destroy it.

NewsE coli-based water monitoring technology homes in on heavy metal contamination
Researchers have created an E coli-based water monitoring technology that uses the bacterium as a live sensor to detect heavy metal contamination in water.

NewsRestricting antibiotics for livestock could curtail spread of AMR infections in people
A California policy restricting antibiotic use in animals raised for food is associated with a reduction in one type of antibiotic-resistant infection in people in the state, according to a new study.

NewsElectrochemical energies yield insights into how bacteria may develop antibiotic tolerance
Researchers investigated variations in the electrochemical energies that power bacterial growth to understand how bacteria develop antibiotic tolerance without acquiring new genes or mutating existing ones.

NewsHarmful bacteria can elude predators when concealed in mixed colonies
Efforts to fight disease-causing bacteria by harnessing their natural predators could be undermined when multiple species occupy the same space, a new study has revealed.

NewsGenetically engineered bacterium can synthesize melanin nanoparticles
Researchers have heterologously expressed a tyrosinase gene in Escherichia coli to synthesize melanin nanoparticles which offer potential for tumour treatment.

NewsProtective bacterial cultures offer promise for antibiotic resistant salmonella in food
UConn researcher Dennis D’Amico and his team looked at the ability of a protective culture called Hafnia alvei B16 to prevent infection by two Salmonella serovars, a grouping within the Salmonella enterica species.

NewsResearchers uncover role of sulphides in aerobic/anaerobic switching in bacteria
A research team has cast fresh light on the special mechanisms by which bacteria in the human intestinal tract can switch from aerobic respiration to anaerobic respiration depending on their environment.

NewsScientists show how livestock systems act as a reservoir for antimicrobial-resistant bacteria
Scientists from the International Livestock Research Institute (ILRI), the University of Liverpool, the University of Edinburgh and elsewhere have traced how livestock systems act as a reservoir for antimicrobial-resistant (AMR) bacteria and AMR genetic determinants that may infect or colonize people.

NewsInternational team tracks the global spread of antimicrobial resistance
An international research team has provided valuable new information about what drives the global spread of genes responsible for antimicrobial resistance (AMR) in bacteria.

NewsLiquid-coated air filter inspired by carnivorous plant can improve early capture of airborne pathogens
Researchers have designed a new liquid-coated air filter that allows for improved early detection and analysis of airborne bacteria and viruses, including the one that causes COVID-19.

NewsGull droppings undermine efforts to control spread of colistin-resistance genes
Gull droppings at beaches in the Porto region of Portugal are riddled with bacteria that are resistant to the ‘last-resort’ antibiotic colistin, undermining efforts in the livestock sector to reduce colistin-resistance, according to a paper published in Environmental Microbiology, an Applied Microbiology International publication. Researchers at the ...
