NewsA universal toolkit for editing bacterial DNA
A major collaboration involving nine labs has transferred a particularly useful DNA editing system from E. coli into 14 new species of bacteria, spanning three major branches of the bacterial family tree.

NewsAutomation platform enables high-resolution spatial mapping of microbial communities
Researchers have developed a sequential error-robust FISH spatial mapping platform (SEER-Map) which enables fully automated, high-multiplexity spatial profiling of complex microbial communities at single-cell resolution.

NewsResearchers deploy phage therapy in new frontier against antimicrobial resistant infectious diseases
A revelatory treatment for patients with life-threatening infectious diseases is being pioneered in Melbourne. VICPhage, a clinical partnership between The Alfred and Monash, is one of the first in Australia to offer end-to-end capacity in phage therapy to treat some of the most challenging infections.

NewsGut microbiota impacts resistance to bacterial pneumonia: Study
A gut-lung connection influences susceptibility to infection by Acinetobacter baumannii, according to a new study. Investigators found that antibiotics disrupt the gut microbiota, suppress protective immune system pathways in the lungs; and increase the severity of pneumonia.
-
NewsGene-sharing myth challenged as bacteria shown to police DNA exchange
A new study reveals that bacteria can actively limit the spread of antibiotic resistance genes, using a newly characterized mechanism that blocks DNA transfer between cells. It focuses on how bacteria exchange genetic material through tiny intercellular bridges known as nanotubes.

NewsDetailed map of life-threatening Vibrio bacteria reveals new target for treatment
Scientists have mapped in unprecedented detail the structure of Vibrio bacteria, which can cause life-threatening infections linked to antibiotic resistance. The team behind the study say the finding could provide new targets for life-saving treatment.

NewsDrip-irrigated halotolerant PGPB boost jujube yield and quality in saline soils by reshaping soil bacterial communities
A new study demonstrates that applying halotolerant plant growth-promoting bacteria (PGPB) via drip irrigation during the crop growth period can effectively alleviate soil salinity stress, enhance jujube productivity and fruit quality, and restructure rhizosphere bacterial communities in saline agricultural soils.

NewsCinnamic acid blocks plasmid conjugation to slow antibiotic resistance spread
A new study reveals that cinnamic acid, a widely used food additive found in cinnamon, can effectively inhibit plasmid‑mediated conjugation, a major route for the global spread of antibiotic resistance genes (ARGs).

NewsTiny switch controls rare rotary machine in bacteria - and can even reverse direction of spin
Researchers have discovered a tiny molecular switch that can control and reverse the direction of a rare rotary machine linked to motility, surface colonization and protein secretion in bacteria.

NewsYellow food coloring changes gut microbiome in early life
Researchers found that the gut microbiotaof young rats changed with exposure to acceptable daily intake levels of the food coloring tartrazine. The males showed increases in bacteria linked to low-grade inflammation and they also did not gain as much weight as was expected.

NewsCosmetics from waste? New microbial discovery could enable more sustainable production of high-value chemical products
Researchers have made a key discovery about how certain bacterial strains produce a set of economically valuable chemicals — opening the door to new, more sustainable production methods. A family of molecules could be made via bacterial fermentation instead of from palm oil, as they are today.

NewsNew insights into how bacteria manage DNA
New analytical methods have enabled researchers to uncover how the sequence, physical shape and flexibility of bacterial DNA guide the activity of an enzyme called DNA gyrase, which previously got all the credit for managing DNA.

NewsHigh levels of gut bacterial toxin trigger lupus nephritis
Research suggests that using antibiotics to target the Ruminococcus gnavus lipoglycan, or the protein it activates on immune cell surfaces to amplify damaging inflammation, could serve as an alternative to current lupus nephritis therapies that suppress the immune system.

NewsResearchers fight oral cancer with bioengineered chewing gum
Research shows that antiviral and antibacterial chewing gums reduce the levels of three microbes linked to worse outcomes in oral cancers, paving the way for more effective and affordable therapies.
-
NewsResearch on tick-transmitted disease reveals potential weakness, opening paths to new treatments
Tularemia is a rare but highly infectious disease caused by Francisella tularensis, a bacterium that can evade immune defenses. Scientists have isolated and studied a set of proteins that play a central role in infection, revealing a potential weakness.

NewsNew research reveals mechanisms behind coffee’s positive effects on the gut-brain axis
First of its kind research shows the potential role of coffee as a further intervention to promote positive gut health and its effects on the gut-brain axis. Coffee was found to positively affect perceived mood and stress levels in individuals taking part in this study.

NewsE. coli and ‘good’ bacteria balanced by breastmilk in baby gut microbiomes
Sugars contained exclusively in breast milk are helping to feed an important balance of bacteria in babies’ developing gut microbiomes, according to a study that describes how babies who are breastfed maintain a mutually beneficial co-existence of E. coli and Bifidobacterium.

NewsResearchers disable antimicrobial resistance in cystic fibrosis-associated bacteria
A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.
-
NewsMetagenomic software advance boosts research into microbial diversity
Researchers studying the diversity of microbes in environmental samples now have access to a new tool that opens the door to cheaper, more accessible analysis of their samples.

NewsNew lactic acid bacteria for plant-based yogurt alternatives
Researchers find that a particular type of lactic acid bacteria has considerable potential for producing plant-based yoghurt alternatives. The bacteria inhibit potentially harmful bacteria and break down sugars that can cause stomach discomfort.
