NewsAntimicrobial use in agriculture can breed bacteria resistant to first-line human defences
A new study has shown that overuse of antimicrobials in livestock production can drive the evolution of bacteria more resistant to the first line of the human immune response.

NewsBacteria’s antibiotic-evading super polymers do best in harsh conditions of the gut
New research has shown that gut bacteria’s extracellular appendages known as F-pili are stronger in the turbulent conditions of the gut, helping the bacteria transfer resistance genes to each other more efficiently and to clump into ‘biofilms’ – protective bacterial consortia – that help them fend off antibiotics.

NewsVesicles produced by intestinal bacteria cause a malignant cycle in patients with cirrhosis
Researchers have revealed that small vesicles, around 100 nm in size, released by intestinal bacteria induce immune activation and progression of liver cirrhosis, as well as reduction of serum albumin level, subsequently leading to oedema and ascites.

NewsWARNING - GRAPHIC IMAGES: War in Ukraine fuelling rise in injuries infected with multi-drug resistant bacteria
New research being presented at this year’s ECCMID highlights the devastating impact of war injuries with complex bone and soft-tissue multidrug-resistant infections suffered by 13 civilians and one soldier during the war in Ukraine, who were transferred to Germany for specialist treatment.

NewsStudy suggests antibiotic-resistant “superbugs” are being passed between dogs and cats and their owners
Evidence that multidrug-resistant bacteria are being passed between pet cats and dogs and their owners will be presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark (15-18 April).

NewsGold-based antibiotics shine through in battle against multi-drug resistant superbugs
Several gold-based compounds with the potential to treat multidrug-resistant ’superbugs’ have been identified in new research being presented at this year’s ECCMID.

NewsEngineered E. coli delivers therapeutic nanobodies to the gut
A genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.

NewsResearchers solve the cell structure responsible for travellers diarrhoea
Researchers have found that pili used by enterotoxigenic Escherichia coli to attach to host intestinal epithetlia are fine-tuned for their preferred microenvironment, such as the gut or the urinary tract.

NewsWhat’s stopping bacteria from becoming biofactories that transform toxic metals into metallic nanoparticles?
A research group working on using microbes to transform toxic metals into valuable metallic nanoparticles has designed a form of E. coli that can resist 1,000 times more tellurite than its wild-type counterpart.

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.
