A new bacterial strain, Noda2021, belonging to Candidatus phylum Dependentiae has been isolated and sequenced, revealing its genetic material and potential ecological significance. This discovery sheds light on the diversity of microorganisms in Japan's microbiological hotspots.
Researchers found that nitrate triggers Salmonella bacteria to switch from a sessile, biofilm lifestyle to a motile, free-swimming lifestyle in the intestine. This switch enables the bacteria to cause active infection and establish transmission to a new host.
Beneficial gut microbes transfer genes to acquire vitamin B12, increasing their ability to survive. This process, called bacterial sex, allows them to form a tube that DNA can pass through to another cell, demonstrating the horizontal gene exchange among microbes.
Researchers at Nagoya City University developed a novel approach for surface disinfection using harmless visible light, inactivating bacteria and viruses. The study's findings suggest that photothermal effects caused by pulsed laser irradiation can instantly destroy pathogenic microorganisms.
Researchers at the University of Copenhagen have discovered that resistant bacteria can hide resistance genes in inactive bacteria within biofilms, creating a reservoir of resistance that can be drawn upon when antibiotics are not present. This new understanding challenges the long-held assumption that resistant bacteria lose their res...
Engineered biofilms made of E. coli bacteria exhibit emergent drug resistance properties when printed using the new technique. This study provides valuable insights into harnessing the beneficial aspects of biofilms while combating their negative effects, potentially leading to breakthroughs in medicine and materials science.
A research team has identified a bacterium responsible for producing palmerolide A, a melanoma-fighting compound found in Antarctic sea squirts. The discovery could lead to the development of naturally-derived treatments for skin cancer.
Researchers have discovered a specific type of gut bacteria in bees that can improve memory, with bumblebees showing enhanced memory when fed this bacteria. The study suggests a causal link between the gut microbiome and cognitive abilities, opening up possibilities for similar effects in humans.
A study by Anglia Ruskin University has identified potentially dangerous Pseudomonas bacteria in 21% of wild bird faeces collected from locations near the River Cam. The bacteria, which can be passed on to humans through cross-contamination, were resistant to multiple antibiotics.
Researchers at Karolinska Institutet have discovered a new group of small antibacterial compounds that inhibit the formation of bacterial cell walls, showing promise against antibiotic-resistant strains. The molecules work by binding to lipid II, a crucial molecule for bacterial cell wall construction.
Researchers have identified specific skin microbiome bacteria and their pathways as contributing to ageing skin. The study, published in PLOS ONE, used a novel approach to chart host-microbe co-metabolism in skin aging.
Researchers found that levels of REG3G, a natural antimicrobial molecule, fluctuate on a circadian rhythm prompted by resident gut bacteria. This cycling has significant consequences for the ability to fight off infection, with higher bacterial burdens and rates of death when exposed at sunset.
