NewsHeme-based sulfide sensing in bacteria: a new target for antibiotics
Heme binding to a bacterial transcription factor is critical for hydrogen sulfide (H₂S) signaling, a new study reveals. Heme binding promotes the reaction of H₂S with the transcription factor, leading to structural changes that can regulate stress tolerance in bacteria.

NewsBroccoli seeds can spread resistance to multiple fungicides
Researchers who screened commercial broccoli seeds for Alternaria brassicicola, a fungal pathogen, found that seeds can harbor A. brassicicola and can spread resistance to multiple fungicides. Based on the findings, the researchers developed a faster way for detecting and monitoring fungicide resistance.

NewsZoo poo might hold the secrets to new medical treatments
Scientists are hoping the collection of poo from tigers, elephants, giraffes and other exotic animals, could contain the secret to finding new medical treatments. Although a waste product to the animals, hidden amongst it are thousands of phages which are potentially capable of fighting bacterial infections.

NewsStudy detects multidrug-resistant KPC-producing bacteria in Chilean wastewater for the first time
A team of Chilean researchers has identified, for the first time in the country, the presence of KPC-type carbapenemase-producing bacteria in wastewater samples from the Greater Concepción Metropolitan Area.

NewsCommon painkillers linked to antibiotic resistance
Ibuprofen and paracetamol are common over-the-counter medications that many of us reach for when we’re sick. But new research shows that these trusted staples are quietly fuelling one of the world’s biggest health threats: antibiotic resistance.

NewsBacteria strains infecting cattle and humans in US are highly similar
Salmonella Dublin, a type of bacteria that primarily infects cattle but some strains also can adapt to infect humans, is increasingly becoming resistant to antibiotics, making it a growing public health threat.

NewsResearchers use generative AI to design compounds that can kill drug-resistant bacteria
With help from artificial intelligence, researchers have designed novel antibiotics that can combat two hard-to-treat infections: drug-resistant Neisseria gonorrhoeae and multi-drug-resistant Staphylococcus aureus (MRSA).

News‘Essentiality’ scan reveals microbe’s ‘must-have’ list
Researchers have spent years taking apart one of the world’s simplest microbes, Mycoplasma pneumoniae, piece by piece, and created a detailed list of what molecular parts the living cell can and cannot do without.

News CRISPR-based therapeutics hold potential to combat AMR and cure chronic viral infections, says GlobalData
CRISPR-based therapeutics show potential to combat antimicrobial resistance (AMR) and deliver functional cures for chronic viral infections, says GlobalData, a leading data and analytics company.

NewsLaser therapy enhances treatment of fungus resistant to conventional medication
Researchers have managed to reduce Candida albicans’ resistance to fungicides by incorporating photodynamic inactivation techniques into the treatment. The technology can be used in both human healthcare and the prevention of food contamination.

NewsBee and frog proteins: nature’s double defense against farm superbugs
A new study reveals that combining natural antimicrobial peptides can significantly slow the development of antimicrobial resistance in bacteria. Using two peptides together prevents harmful bacteria from mutating as quickly, offering a promising alternative to traditional antibiotics.

NewsMultidrug-resistant bacteria spread from war-zone hospitals to other countries
After Russia’s full-scale invasion, thousands of patients were transferred from Ukraine to other European countries. Researchers in Helsinki found that 8% of Ukrainian refugees had been hospitalised due to war injuries. Almost 80% of them carried multidrug resistant bacteria.

NewsCopper antimicrobials can drive antibiotic resistance in bacteria, but there’s a fix, scientists say
Microbiologists have found that heavy use of copper antimicrobials can drive antibiotic resistance in bacteria. However, resistance quickly diminishes without copper exposure, suggesting that copper could help reduce antibiotic resistance if alternated with other measures.

NewsMicrobial map reveals countless hidden connections between our food, health, and planet
A new map of ‘agri-food system microbiomes’ reveals how players at every stage of the food system can restore and protect dwindling microbiomes to help boost human and planetary health.

NewsHospital superbugs that cause sepsis and meningitis could be hitching a ride on mobile phones
Hospital superbugs that cause sepsis and meningitis could be hitching a ride on mobile phones, allowing them to escape out of healthcare settings and into the community, according to research presented at MLS Future Forum earlier this year.

NewsExperiment on joint NASA and SpaceX mission will study the effect of space travel on disease-causing bacteria
ARC/Sheba Medical Center is launching an Israeli experiment on the International Space Station to investigate how microgravity and space conditions influence bacterial virulence and antibiotic resistance.

NewsHow bacteria use a protein associated with Alzheimer’s to fight off threats
Amyloids are perhaps best known as a key driver of Alzheimer’s disease. According to new research, these oft-maligned proteins also serve a critical role for bacteria in our environment, enabling them to fight off other “predatory bacteria.”

NewsNew tool helps predict antibiotic resistance
Researchers have developed a platform that identifies drug resistance genes already circulating in the environment before they emerge in the clinic and directly couples this information to the design of resistance-evasive antibiotics.

NewsReviving 80-year-old fungi offers new clues for sustainable agriculture
Researchers who revived 80-year-old fungal pathogens from a museum collection found that these pre-Green Revolution strains differ significantly from modern ones, revealing how decades of pesticide use and intensive farming have reshaped plant pathogens.

NewsNew insights could help phages defeat antibiotic resistant bacteria
Researchers have worked out how bacteria defend themselves against viruses called phages and the new insights could be key to tackling antibiotic resistance. The new research is the first to describe how a bacterial defence mechanism against phages, called Kiwa, works.
