NewsSloth fur may carry antibiotic-producing bacteria
The fur of Costa Rican sloths appears to harbour antibiotic-producing bacteria that may hold a solution to the growing problem of antimicrobial resistance.
-
NewsPredatory soil protists may boost PGPB activity
Bacterivorous soil protists may regulate the activity of plant growth promoting bacteria (PGPB), boosting plant growth even further, according to a new study.
-
NewsPreemie infections may come from gut microbiomes
Dangerous bacterial bloodstream infections in premature babies may originate from the infants’ gut microbiomes, according to researchers.
-
NewsReef grazer fish faeces is deadly to coral
Faeces from fish that are typically thought to promote healthy reefs can damage and, in some cases, kill corals, according to a recent study.
-
NewsMachine learning helps to ID microbe preferences
Researchers have figured out a way to predict bacteria’s environmental pH preferences from a quick look at their genomes, using machine learning.
-
NewsGut microbiome fluctuates through days and seasons
The balance of microbes in the human gut varies substantially from morning to night and even more by season, with profound fluctuations completely transforming the microbiome from summer to winter, a new study reveals.
-
NewsSensor controls how dormant bacteria reawaken
Researchers have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly spring back to life.
-
NewsAchilles heel is uncovered in Helicobacter pylori
Researchers have discovered a weakness in the bacterium Helicobacter pylori, which could be exploited to develop new drugs.
-
NewsPhage delivers double whammy against biofilms
A novel bacteriophage isolated from sewage water not only kills its target bacteria in the Klebsiella oxytoca complex but was unexpectedly found to be capable of disrupting biofilms produced by these bacteria.
-
NewsCyanobacteria membrane proteins similar to animals’
A dynamin-like protein, namely SynDLP, has been identified in the genome of a cyanobacterium.
-
NewsGlobal prevalence of H. pylori infection declining
Researchers have found that Helicobacter pylori (H. pylori) infection around the world has been steadily declining over the past four decades, and that the use of antibiotics against it could alter the micro-organisms and the virus community present in the gut.
-
NewsUnknown bacteria key players in ocean energy cycle
Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean.
-
NewsNew method may harness radiation-resistant bacterium
Researchers find a novel way to expand applications of the hardy bacterium Deinococcus radiodurans, using gene deletion techniques.
-
NewsAntimicrobial use in agriculture can breed bacteria resistant to first-line human defences
A new study has shown that overuse of antimicrobials in livestock production can drive the evolution of bacteria more resistant to the first line of the human immune response.
-
NewsStool transplants more effective than antibiotics for treating recurring, life-threatening gut infections
A new Cochrane Review has found that, compared with standard antibiotic treatment, stool transplantation can increase the number of people recovering from Clostridioides difficile infection from 40% to 77%.
-
NewsNew biologic effective against major infection in early tests
Researchers have shown in early tests that a bioengineered drug candidate can counter infection with Staphylococcus aureus – a bacterial species widely resistant to antibiotics and a major cause of death in hospitalized patients.
-
NewsBacteria’s antibiotic-evading super polymers do best in harsh conditions of the gut
New research has shown that gut bacteria’s extracellular appendages known as F-pili are stronger in the turbulent conditions of the gut, helping the bacteria transfer resistance genes to each other more efficiently and to clump into ‘biofilms’ – protective bacterial consortia – that help them fend off antibiotics.

FeaturesEarth Day 2023
Celebrating Earth’s microbiomes and how we can harness unusual microbes for wider applications around the world.

News New cell-killing toxin discovered in an environmental pathogen
An international research team has discovered how a bacterial toxin, known as Ssp, is capable of entering and killing a wide range of living cells, including human cells.

NewsVesicles produced by intestinal bacteria cause a malignant cycle in patients with cirrhosis
Researchers have revealed that small vesicles, around 100 nm in size, released by intestinal bacteria induce immune activation and progression of liver cirrhosis, as well as reduction of serum albumin level, subsequently leading to oedema and ascites.
