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.

NewsCentauri Therapeutics selects first clinical candidate for immunotherapeutic treatment of Gram-negative bacterial infections
Centauri Therapeutics Limited has announced the selection of its first clinical candidate in the ABX-01 programme. The compound is designed to target serious Gram-negative bacterial infections in the lung.

NewsStudy uncovers how low-carb diet drives colorectal cancer development
A new study suggests that a low-carbohydrate diet promotes the growth of a strain of E. coli that produces DNA-damaging colibactin, which drives genetic mutations and predisposes tumour development.

NewsStudy uncovers the core principles of low-resistance antibiotics
Researchers have demonstrated that a dual-target approach, combining membrane disruption with an additional critical cellular pathway, significantly prevents the development of resistance in bacteria.

NewsCan Rhizobium + low P increase the yield of common bean in Ethiopia?
A study found that bean inoculation with Rhizobium alone or in combination with P application, can increase grain yield of two common bean cultivars in Ethiopia.

NewsProactively exposing ecosystems to mild environmental stressors appears to offer protection
Mild, proactive exposure to environmental stress can help biological communities resist severe disturbances and maintain genetic diversity, a recent study has found.

NewsMotion capture: In a world first, motility apparatus of Mycoplasma mobile clarified
Mycoplasmas, including bacteria that cause pneumonia in humans, are generally nonmotile, but Mycoplasma mobile, as the species name suggests, has been found in the gills of fish and seems to move by gliding along surfaces. The molecular structure that allows it to do so has for the first time been ...
