News‘Hangry’ bacteria pump out toxins, unlike their identical but well-fed colleagues
New study shows that genetically identical cells within a bacterial community have different functions, with some members behaving more docile and others producing the very toxins that make us ill.

NewsScientists reveal how getting physical can tackle a key hurdle in synthetic biology
A team of scientists may have solved one of the biggest hurdles standing in the way of synthetic biology - the difficulty of transferring the resulting large DNA molecules into bacterial host cells.

NewsOutbreak of typhoid on Dutch ship traced to contaminated drinking water in corroded tank
A large outbreak of typhoid on a ship in the Netherlands was traced to contaminated water, this year’s ECCMID 2023 will hear.

NewsFruit fly gut remodels itself to create home for beneficial microbiome species
The digestive tract of fruit flies remodels itself to accommodate beneficial microbiome species and maintain long-term stability of the gut environment, according to new research.

NewsResearchers solve the cell structure responsible for travellers diarrhoea
Researchers have found that pili used by enterotoxigenic Escherichia coli to attach to host intestinal epithetlia are fine-tuned for their preferred microenvironment, such as the gut or the urinary tract.

NewsWhite-tailed deer blood kills bacteria that causes Lyme disease
The blood of the white-tailed deer kills the corkscrew-shaped bacterium that causes Lyme disease, a potentially debilitating illness.

NewsIntestinal contents of thrushes killed in window collisions reveal shifting gut microbiomes
A study of bodies of migratory birds killed in window collisions over the years helps to uncover the relationship between birds and the microbes living in their guts—which appears to be wildly different from mammals and their microbiomes.

NewsCoastal ecosystem shows shifting bacterial extracellular hydrolytic systems
Scientists have found that a coastal ecosystem that experiences periodic phytoplankton blooms appears to have two distinct bacterial extracellular hydrolytic systems linked to shifts in bacterial community structure.
-
NewsMethanogen genomes reveal how life thrives in extreme conditions
A comparison of the genomes of methane-producing microorganisms reveals that temperature adaptation might not be genomically encoded, but rather enforced through protein regulation and finer scale adaptations in amino acids.
-
NewsScientists developing drug candidates that could prevent germination of C diff
New research could lead to a drug that susceptible people take before infection starts.

NewsBlocked cell wall formation stops bacterial cell division
Researchers using high-performance microscopes to observe the effect of different antibiotics on Staphylococcus aureus have clarified how exactly different antibiotics block cell division within a few minutes.
-
NewsmNGS outperforms microbiological tests to diagnose bloodstream infections
Next-generation sequencing (mNGS) leverages genetic testing advantage to save more lives and is found to be twice as effective at identifying infection cases.

NewsEurope set to miss 2030 SDG target for ending TB as global threat
A new paper examining progress towards the Sustainable Development Goals target for tuberculosis and associated targets warns that as it stands, the EU/EEA will not reach the set targets by 2030.

NewsWater quality standards ‘should be reviewed to reflect AMR threat’
Water quality standards should be reviewed to reflect the threat from the spread of antibiotic resistance, a team of scientists has warned.

NewsScientists warn of rise in flesh-eating bacterial infection due to global warming
Continued warming of the climate would see a rise in the number and spread of potentially fatal infections caused by bacteria found along parts of the coast of the United States, researchers predict. Vibrio vulnificus bacteria grow in warm shallow coastal waters and can infect a cut or insect bite ...

NewsCo-infection with ‘superbug’ bacteria increases SARS-CoV-2 replication up to 15 times
New research has revealed that IsdA, a protein found in all strains of Staph A., boosts SARS-CoV-2 replication by 10- to 15-fold.
-
NewsExtensively drug-resistant Shigella sonnei strain emerges in France
Scientists monitoring Shigella in France have detected the emergence of extensively drug-resistant (XDR) strains of Shigella sonnei. Bacterial genome sequencing and case characteristics suggest that these strains, which originated in South Asia, mainly spread among men who have sex with men.

NewsCarbon limitation boosts survival of beneficial bacterium in the human gut
Yale researchers have discovered that one of the most abundant beneficial species found in the human gut showed an increase in colonization potential when experiencing carbon limitation — a finding that could yield novel clinical interventions to support a healthy gut.
-
NewsStudy shines new light on ancient microbial dark matter
An international research team reveals a first in-depth look at Omnitrophota – one of the world’s oldest and tiniest bacteria.

NewsWHO warns of dearth of new antibiotics, especially those targeting drug-resistant pathogens
A review from WHO on the number of new antibiotics currently in the pipeline shows that just 12 new antibiotics have entered the market in the five years from 2017-21.
