News City birds found to be carriers of antimicrobial resistant bacteria
Researchers have found that wild birds such as ducks and crows living close to humans, for example in cities, are likely to carry bacteria with antimicrobial resistance (AMR).
-
NewsRaw meat based diets for pets are carrying multi-drug resistant pathogens
Raw meat-based diets for pets can serve as a vehicle for multi-drug resistant pathogens, posing significant risks to their owners, a new study has found.
-
NewsInfected bacteria fight back with ‘hidden’ genes that halt cell growth, slow viral spread
Researchers have uncovered a surprising way bacteria defend themselves: when a bacterium is infected, bacterial enzymes that copy genetic information from RNA into DNA synthesize genes whose protein products help shut down cell growth.

NewsNasal microbiome: friendly pirates deprive multi-resistant bugs of iron
A new study reveals that whether dangerous staphylococci survive in the nose depends on what other bacteria are present – and how they obtain iron.
-
NewsFungi elude antifungal treatments by restructuring cell walls
A new multi-institutional study has characterized how fungi adapt to restructure their cell walls, effectively thwarting current antifungal medications. This new information opens opportunities to devise more effective use of antifungal drugs.
-
NewsSuperbugs spread to family members of recently hospitalized patients
Family members of patients recently discharged from hospital may have a higher risk of getting an antibiotic-resistant infection, even if the patient was not diagnosed with the same infection, suggesting hospitals play a role in community spread of resistant bacteria.
-
NewsBacterial gut diversity improves the athletic performance of racehorses
The composition of gut bacteria of thoroughbred racehorses at one-month-old can predict their future athletic performance, according to a new study.
-
NewsResearchers discover new Candida auris – a possible global public health threat
Researchers have discovered a new clade (or type) of Candida auris, bringing the number of clades known globally to a total of six.
-
NewsResearchers discover source of deadly fungal infections in bone marrow transplant patients
Scientists have found that heteroresistance is the reason a small number of transplant patients developed bloodstream infections, despite receiving prophylaxis with the antifungal drug micafungin.
-
NewsScientists solve mystery of bacterial scavenging machinery
Scientists investigated how the oleate shuttle from FakB2 to FakA kinase works in the Fak system, which is exploited by the zoonotic pathogen Streptococcus suis (S. suis) pathogen to scavenge exogenous fatty acid (eFA).
-
NewsCoinfecting viruses impede each other’s ability to enter cells
Scientists researching phage infection at the level of a single cell investigated whether the number of infecting phages that bind to the bacterial surface corresponds to the amount of viral genetic material that is injected into the cell.
-
NewsSuper cally molecules take down tuberculosis
Researchers have identified and synthesised a group of molecules that can act against the cause of tuberculosis in a new way. The callyaerins act against TB by employing a fundamentally different mechanism compared to antibiotic agents used to date.
-
NewsNew compound found to be effective against flesh-eating bacteria
Researchers have developed a novel compound that effectively clears bacterial infections in mice, including those that can result in rare but potentially fatal ‘flesh-eating’ illnesses, and could be the first of an entirely new class of antibiotics.
-
NewsHuman clinical study launched using phage lysin to eliminate staph in the nasal microbiome
A “first-in-human” study with the novel drug candidate HY-133 began on 10 July with the recruitment of clinically healthy volunteers who tested positive for Staphylococcus aureus colonisation of the nose.
-
NewsCopper oxide nanoparticles to counter pathogens are synthesized from mango
Researchers have synthesized green copper oxide nanoparticles from Mangifera indica leaf extract. They showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on persimmon fruit pathogens.
-
NewsAI opens door to safe, effective new antibiotics to combat resistant bacteria
A large language model—an AI tool like the one that powers ChatGPT—has been used to engineer a version of a bacteria-killing drug that was previously toxic in humans.
-
NewsDerivative of the long pepper battles bacterial biofilms
Scientists investigating the long pepper - known in traditional medicine for its treatment of a variety of illnesses - have created a derivative that disrupts bacterial chemical communication.
-
NewsDual action antibiotic could make bacterial resistance nearly impossible
A new antibiotic that works by disrupting two different cellular targets would make it 100 million times more difficult for bacteria to evolve resistance, according to new research
-
NewsNew agent effective against drug-resistant malaria parasites
Scientists have developed a promising new antimalarial agent, DIF-1(+3), which is a derivative of Dictyostelium differentiation-inducing factor-1 (DIF-1).

NewsNew UK research networks will tackle antimicrobial resistance
Eight new UK networks, combining different research specialisms, will work together to tackle one of humanity’s biggest threats, antimicrobial resistance (AMR).
