NewsThe gut bacteria that put the brakes on weight gain in mice
Research has identified a specific type of gut bacteria, called Turicibacter, that improves metabolic health and reduces weight gain in mice on a high-fat diet. People with obesity tend to have less Turicibacter, suggesting that the microbe may promote healthy weight in humans as well.

NewsRising heat reshapes how microbes break down microplastics, new review finds
A new review examines how high and extreme temperatures influence the ability of microorganisms to degrade microplastics. The authors show that heat can both accelerate and suppress microbial breakdown of plastic particles, depending on conditions and the organisms involved.

NewsFor certain life-essential proteins in E. coli, repair is more likely
A new study shows that E. coli proteins containing a specific structure are more likely to misfold and, if they are required the bacteria’s survival, more likely to be repaired.

NewsStudy reveals high stakes of early immune development—and a potential probiotic fix
Scientists find that certain gut bacteria are essential for building immune defenses during infancy, pointing to new strategies for protecting children’s health. They have identified a way to preserve healthy immune development even when infants need antibiotic treatment.

NewsCancer-fighting bacterial product ‘cocktails’ may offer personalized treatment
Bacteria may be the next frontier in cancer treatment, according to researchers who devised a new approach of creating bacteria-derived mixtures — or cocktails — to help fight bladder cancer. They found that the cocktails significantly boost the immune system’s ability to fight cancer.

NewsSoil bacteria and fungi emerge as a top predictor of childhood allergic disease
The unique blend of fungi and bacteria in a region’s soil may be the strongest factor explaining its rates of childhood allergic disease, with certain assemblages of soil critters appearing linked with better health outcomes, according to new research.

NewsNew one-two punch could knock out drug-resistant TB
Researchers found that pairing the antibiotic rifampicin with a second compound turned multidrug resistance into a weakness—providing proof of concept for using basic science to design life-saving dual-drug strategies.

NewsCan certain bacteria regulate aging of the immune system and its related alterations?
Researchers have discovered a strain of Lentilactobacillus capable of preventing and even reversing aging-related immune alterations. Feeding aged mice with heat-inactivated YRC2606 resulted in lowered levels of inflammatory cytokines and signaling proteins.

CareersCBCTA 2024 oral presentation winners: Isabella and Lia take home the honours
Letters in Applied Microbiology sponsored the best oral presentation award at the 29th Brazilian Congress of Food Science and Technology (CBCTA 2024). Winner Isabella Bassoto Xavier and runner-up Lia Mariano Aquino take a dive into their research.

NewsUnseen allies: symbiotic bacteria help clean wastewater, but there is a catch
Scientists have identified new species of denitrifying endosymbionts in wastewater, highlighting their global prevalence – with an unexpected climate implication.
-
NewsGut bacteria from amphibians and reptiles achieve complete tumor elimination
Researchers have discovered that the bacterium Ewingella americana, isolated from the intestines of Japanese tree frogs (Dryophytes japonicus), possesses remarkably potent anticancer activity.

NewsA fatal mix-up: How certain gut bacteria drive multiple sclerosis
If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to attack its own nervous system. This mechanism can accelerate the progression of multiple sclerosis.

NewsOroya fever: Elucidation of disease mechanism opens possibility for novel therapy
An international research team has generated and analyzed more than 1,700 genetic variants of the pathogen that causes Oroya fever, identifying two proteins that Bartonella requires for the destruction of red blood cells.

NewsStreptococcus suis serotype 2 collagenase-like protease promotes meningitis by increasing blood-brain barrier permeability
Streptococcus suis serotype 2 (SS2) is an emerging zoonotic pathogen that causes meningitis in humans and pigs. Researchers have investigated the role and mechanism of the SS2 Clp in promoting the passage of the bacterium across the blood-brain barrier (BBB).

NewsHarmless Klebsiella strain shows powerful protection against gut infections in Inflammatory Bowel Disease (IBD) model
A new study demonstrates that a harmless strain of Klebsiella can eliminate infections and reduce gut inflammation in mouse models of inflammatory bowel disease (IBD).

NewsSwedish freshwater bacteria give new insights into bacterial evolution
Researchers analyzing the DNA of all known Caulobacterales species, including newly collected samples from Swedish and Finnish forest lakes, discovered that several freshwater species lacked more than a hundred genes typically linked to the group’s complex lifecycle.

NewsNovel kirkovirus may be associated with colitis in horses
In a pilot study, researchers have found a novel kirkovirus that may be associated with colitis – and potentially small colon impactions – in horses. The study could offer a route to new therapies for horses with colitis symptoms from unknown causes.

NewsFecal tests reveal active termite attacks
Termite pellets can linger long after the insects that dropped them have disappeared. By testing for microbes in the excrement, researchers can distinguish old droppings from fresh, and whether a colony is actively chewing its way through a home.

NewsStudy links gut bacteria to bloodstream infections in newborns within sub-Saharan Africa for the first time
New research has shown gut and bloodstream infections are caused by the same bacteria giving hope of better prevention and diagnosis of deadly neonatal sepsis.

NewsCould hidden infections be fueling long COVID?
For millions suffering from long COVID, their persistent breathlessness, brain fog and fatigue remain a maddening mystery, but microbiologists think they may have cracked the case. The review argues that co-infections acquired before or during COVID could cause symptoms to persist indefinitely for many people.
