NewsMicrobiome: Researchers improve bacterial analysis for clinical applications
Different extraction methods can obtain the DNA of certain bacterial species differently, which can significantly distort the determined microbiome composition. Scientists have developed a computer-based method for correcting extraction bias.

NewsResearch team publishes paradigm-challenging discovery in a Yellowstone thermophile
A graduating PhD student has made an interesting discovery about a common thermophilic bacteria dwelling in hots prings which is able to simultaneously respirate and metabolize via aerobic and anaerobic pathways.

NewsNew discovery and grant to accelerate Strep A vaccine efforts
With a large sum of research funding and multinational contributions, the world’s only Strep A human challenge model will be used to resolve logistical issues and speed up the development of a successful Strep A vaccine.

NewsNovel enzyme found in gut bacteria could revolutionize prebiotic research
Researchers have discovered a new β-galactosidase enzyme in a human gut bacterium that breaks down and synthesizes previously unexplored glycans, which have prebiotic capabilities to improve gut health.

NewsBacteria and minerals work together to detoxify arsenic in contaminated soils
New research shows that the interaction between arsenic-oxidizing bacteria and goethite, a common Fe mineral, significantly accelerates the conversion of arsenic from its highly toxic form, arsenite [As(III)], into the less harmful arsenate [As(V)].

NewsSulfur-reducing bacteria team-up to break down organic substances in the seabed
Researchers have decoded the molecular strategies employed by the underappreciated sulfate-reducing bacteria, <i>Desulfobacteraceae</i>, which is capable of breaking down organic carbon in the oxygen-limited seabed.

NewsPurified immunoglobulin F(ab′) 2 prevents lethal staphylococcal enterotoxin B intoxication in mice and rhesus monkeys
Purified F(ab′)2 fragments are an effective antidote to lethal SEB doses in mice and rhesus monkeys, and therefore might be a favorable candidate for treating patients with severe SEB intoxication, a new study suggests.

NewsAntimicrobial resistance in soil bacteria without the use of antibiotics
Overuse of antibiotics is currently the primary reason for the rise of antimicrobial resistance (AMR), but researchers have shown that AMR can be found in soil bacterial communities due to microbial interactions too, driven by a species of predatory bacteria.

NewssiRNA-AGO2 complex inhibits bacterial gene translation: a novel therapeutic strategy for superbug infection
Scientists have demonstrated that exosomes can serve as delivery vehicles to introduce AGO2-loaded siRNA into the cytoplasm of bacteria, and in turn down-regulated gene expression of the mRNA that shares sequence complementarity to the siRNA.
-
NewsBacterial ‘jumping genes’ can target and control chromosome ends
Researchers have discovered a new mechanism that transposons, or “jumping genes” use to survive and propagate in bacteria with linear DNA, with applications in biotechnology and drug development.
-
NewsTB vaccine candidate provides ‘elite’ protection
A tuberculosis vaccine candidate under development shows complete protection and superior immune response in nonhuman primates compared to the existing BCG vaccine.
-
NewsDamaged but not defeated: Bacteria use nano-spearguns to retaliate against attacks
Scientists used state-of-the-art microscopy technology to mimic a nano-speargun, the type VII secretion system, used as a bacterial pinpoint counterattack tactic in response to cell envelope damage against rival bacteria.

NewsPackets of freeze-dried bacteria grow biocement on demand
Researchers report a freeze-drying approach that preserves biocement-producing bacteria, potentially allowing construction workers to use powder out of a packet to quickly make tiles, repair oil wells or strengthen the ground for makeshift roads.

NewsThroat microbiome holds clues to older Australians’ health
A simple swab from the back of the throat, known as the oropharynx, may offer clues about health challenges faced by aged care residents.
-
NewsResearchers see breakthrough in efficient biofuel production
Researchers have found ways to limit the toxicity to microbes generated by the biofuel butanol through fermentation of plant biomass, by manipulating the structure of microbe cell membrane at atomic level.
-
NewsAdaptation to extreme conditions: thermal water biofilm studies could help understand ancient ecosystems
Researchers have discovered unique bacterial communities in thermal waters that may help unravel the development of stromatolites, one of Earth’s oldest rock formations.

NewsLonger breastfeeding linked to blood-pressure lowering effects of certain infant gut bacteria
An observational study has found that infants who had more diverse bacteria in their gut had lower childhood blood pressure, and this protective association was stronger if they were breastfed for at least six months.

NewsWhite blood cells use brute force to dislodge bacteria
A $2.3 million grant from the National Institutes of Health (NIH).will support research into blood platelets and macrophages; how integrin tension influences cell function; and how this force affects platelet behavior.

NewsAMI member Christopher Stewart named as laureate in 2025 UK Blavatnik Awards for Young Scientists
Applied Microbiology International member Professor Christopher Stewart of Newcastle University has been named as one of three 2025 laureates in the eighth Blavatnik Awards for Young Scientists in the UK.

NewsScientists reveal anti-bacterial role of plant metabolite
A study shows that a plant metabolite, erucamide, is able to target and disrupt a protein assembly of Gram-negative bacterial pathogens, thus inhibiting their virulence. Understanding the metabolite’s molecular mechanisms could protect crops from infection.
