NewsFatty acid produced by gut bacteria directly influences fat metabolism in animals
Researchers investigating gut bacteria that produce fatty acids with a special chemical structure, known as a cyclopropane ring, showed that these can be converted into signals that turn on fat desaturation in the nematode C. elegans.

NewsMicrobiome studies explore why more women develop Alzheimer’s disease
Two new studies from the University of Chicago investigate the roles of the gut microbiome and estrogen in the differing rates of Alzheimer’s disease among women and men.

NewsSurge in gonorrhoea cases in Denmark: up by 46% between 2021 and 2022
An observed rise in gonorrhoea cases particularly affected younger women and men who have sex with women, indicating a potential shift in infection and transmissibility dynamics across the country.

NewsResearchers ID decline in microbial genetic richness in the western Arctic Ocean
Small but statistically significant results point to the need for future study, say David Walsh and Arthi Ramachandran.

NewsStudy identifies surge in antibiotic-resistant typhoid
Researchers used whole genome sequencing to identify that S Typhi isolates with mutations evolved locally from the endemic S Typhi population in Blantyre, Malawi, and were not the result of importations from other countries.

NewsScientists reveal what makes ‘bad’ bacteria life-threatening
Researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic resistance.

NewsScientists engineer a coating for disease-free produce
A new wax coating technology bolsters the safety of fresh produce and provides enhanced protection against bacteria and fungi. This composite coating provides both immediate and delayed antibacterial effects, according to the article.

NewsPhotosynthetic mechanism of purple sulfur bacterium adapted to low-calcium environments revealed
Researchers revealed the LH1-RC structures of Allochromatium vinosum, a model species of autotrophic bacteria capable of thriving in low-calcium or soft-water environments, at a resolution that enabled individual amino acid visualization.

NewsVibrio natriegens offers low cost and low capital plasmid engineering
A proposed V. natriegens platform that doesn’t depend upon chitin to become competent can enable the democratization of synthetic biology, especially in education, the authors of a new study suggest.

News‘Pink berries’ reveal how bacteria survive a viral epidemic
Like humans struggling to get through the COVID-19 pandemic, bacterial cells need social distancing to thwart viruses. But in some situations, such as inside elevators or within the candy-colored bacterial structures known as “pink berries,” staying apart just isn’t feasible. Source: Lizzy Wilbanks “Pink berry” bacterial structures. These ...

NewsBacterial metabolite activates another species to produce bad breath
Researchers find that a metabolite produced by the commensal oral bacterium Streptococcus gordonii activates another bacterial species, Fusobacterium nucleatum, to produce the malodorous compound methyl mercaptan.

NewsBacteria in the Arctic seabed are active all year round
Despite the pronounced seasonality in their habitat, the bacterial community in Arctic sediments is taxonomically and functionally very stable, a new study finds.

NewsGargling away the bad bacteria in type 2 diabetes can help to control blood sugar
Researchers have found that gargling with an antiseptic mouthwash can reduce ‘bad’ bacteria in the mouths of people with type 2 diabetes, and may lead to better control of their blood sugar.

NewsNew sepsis test provides faster and reliable results
Doctors received test results two days earlier than before, when they tested a new way to analyze blood samples for suspected sepsis. This could mean life or death for patients at your local hospital.
-
NewsSynthetic antimicrobial molecule is highly effective against multidrug-resistant bacteria
Cresomycin – a novel synthetic molecule – demonstrates remarkably robust efficacy against multiple, evolutionary divergent forms of antimicrobial resistance (AMR), researchers report.
-
NewsDrug-resistant bacterium responds to phage-antibiotic combo therapy
A case study, which required emergency investigational new drug approval from the U.S. FDA, is one of only a handful that have used bacteriophage therapy to treat Enterococcus faecium infection.
-
NewsLow-cost microbe can speed biological discovery
Researchers have created a new version of a microbe to compete economically with E. coli – a bacteria commonly used as a research tool due to its ability to synthesize proteins – to conduct low-cost and scalable synthetic biological experiments.

NewsCompounds released by bleaching reefs promote bacteria, potentially stressing coral further
New research reveals that when coral bleaching occurs, corals release organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.

NewsStudy reveals gut microbiome changes linked to Autism Spectrum Disorder
Researchers have found significant differences in both alpha and beta diversity of the gut microbiome in individuals with ASD, and identify specific types of bacteria found at higher abundance in individuals with autism.

NewsDrought may drive deadly amphibian disease by disrupting skin microbiome
Progressively severe droughts are disrupting the microbiomes of the thumbnail-sized orange frogs, potentially leaving them vulnerable to a deadly fungal disease, according to a new study by an international research team.
