NewsSwimming in rivers and lakes linked to higher risk of stomach bugs and rashes
Researchers have found that people swimming in rivers and lakes were more than twice as likely to develop skin problems, while higher levels of bacteria linked to faecal pollution were associated with an increased risk of stomach bugs.

NewsSurvival of the driest: Directed evolution boosts bacterial tolerance to industrial spray-drying by 1000-fold
Spray-drying is the preferred method for producing dry microbial inoculants for agriculture, offering low cost and easy transport. But many beneficial Gram-negative bacteria struggle to survive the rapid dehydration and heat involved.

NewsPropionate from gut bacterium Akkermansia mitigates liver fibrosis
A recent study has identified the gut commensal bacterium Akkermansia muciniphila as a potent modulator of liver fibrosis.
-
NewsTraditional Chinese medicine compound shows promise against ischemic stroke by targeting the gut-brain axis
Researchers have uncovered new evidence that a polysaccharide derived from the traditional medicinal herb Astragalus membranaceus (Huangqi) can protect against ischemic stroke by acting through an unexpected route: the gut.

NewsEven ancient bacteria possessed intercellular communication structures like humans today
Communication between cells in plants, animals and humans takes place via specialised connecting structures. Researchers have discovered how the regulation of very similar structures was already present in multicellular bacteria.

NewsA bacterial protein fragment drives tissue fibrosis, but antibody treatment can help
A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell’s quality-control system, researchers found in a new study. Meanwhile, blocking corisin with an antibody impeded the damage.

NewsMicrobiome signaling system could open new paths for treating IBS-related constipation
New research expands scientists’ understanding of how the gut microbiome communicates with the body, and how our gut bacteria work together to control intestinal movement.
-
NewsResearcher awarded two NIH grants to advance research on antibiotic-resistant infections
The research is focused on developing new strategies to combat two infectious diseases: catheter-associated urinary tract infections (CAUTIs) and invasive Group A Streptococcus skin infections, both of which are increasingly difficult to treat because of antimicrobial resistance.

NewsDietary tryptophan prevents sepsis
Dietary tryptophan protects against sepsis through gut microbiota-derived metabolites which enhance macrophage bacterial phagocytosis.
-
NewsImmune responses to urinary tract infection linked to birth outcomes
A new study shows that the increased risk of preterm pregnancies associated with urinary tract infection, is linked to the body’s immune response to the infection rather than to the bacteria themselves.
-
NewsFor Legionella bacteria, taking over a cell means playing by its rules
New research demonstrates how a protein produced by Legionella mimics the behavior of the host cell’s own proteins.
-
NewsTuberculosis transmission may hold the key to prevention
Scientists have discovered the specific mechanisms that enable the bacteria responsible for tuberculosis to not only survive drying but also to generate mutations linked to antibiotic resistance.
-
NewsGut bacteria may communicate differently with the human body in patients with Parkinson’s disease
A new study suggests that gut bacteria may send different biological signals in Parkinson’s disease.

NewsEmergence of Stutzerimonas nitrititolerans co-carrying carbapenem and tigecycline resistance from geese in China
Researchers have found strains of Stutzerimonas nitrititolerans with resistance to meropenem and reduced susceptibility to tigecycline in geese feces in Yangzhou, China.

NewsNew approach cuts sepsis diagnosis from days to hours
A research team has developed a way to condense the days-long sepsis diagnosis timeline to just hours, a method which could help clinical decision-making that avoids worsening antibiotic resistance in the bacterial strains causing infections.
-
NewsWastewater may offer an early warning of pertussis outbreaks
Researchers found that pertussis-associated DNA in wastewater rose weeks before reported whooping cough cases, pointing to a new way to complement clinical surveillance.
-
NewsSharpening an essential tool for biotechnology
Scientists develop a database of validated guide RNAs to improve engineering of microbes for manufacturing applications.

NewsMagnetotactic bacteria show potential for extending healthy lifespan
Recently, new research has demonstrated that the magnetotactic bacterium (MTB) Magnetospirillum magneticum can extended healthy organismal lifespan in a Caenorhabditis elegans model.

NewsHerbal residue reshapes gut microbes and lipid metabolism in broilers
A research team found that dietary Radix isatidis herbal residue, a traditional Chinese medicine by-product, may improve growth, mucosal immunity, gut microbiota, and lipid metabolism in broilers.

NewsNew study maps how gut bacteria help and hinder each other’s growth
Researchers have now systematically mapped interactions between common gut bacteria, revealing both competitive and cooperative mechanisms and creating one of the most comprehensive datasets of its kind.
