NewsTraditional herb offers new hope for antibiotic-free pig farming
A new review highlights that Houttuynia cordata extract could serve as a multifunctional natural substitute for antibiotics in swine production. Plant-derived flavonoids, volatile oils, and polysaccharides suppress pathogens including Salmonella, PRRSV, and Streptococcus suis.

NewsHow Mtb safeguards itself from foreign DNA
Researchers have discovered how a key protein in the tuberculosis bacterium helps protect it from the influence of foreign DNA inserted into its genome. Understanding how this protein – called Lsr2 – functions could help develop drugs that target it, thereby aiding in the fight against TB.

NewsNew test shows which antibiotics actually work
Drugs that act against bacteria are mainly assessed based on how well they inhibit bacterial growth under laboratory conditions. A critical factor is whether the active substances actually kill the pathogens in the body. Researchers have presented a new method for measuring how effectively antibiotics kill bacteria.

NewsTB harnesses part of immune defense system to cause infection
Scientists have made a discovery that helps explain why humans and animals are so susceptible to contracting tuberculosis – and it involves the bacteria harnessing part of the immune system meant to protect against infection. They team discovered that MTB survives within the cells of its host by targeting Dectin-1.

NewsBiodegradable and conventional plastics shape very different antibiotic resistance risks in river microbiomes
Biodegradable plastics are not always safer for rivers and oceans, according to a new study that tracked how different plastics change the risk of antibiotic resistant bacteria over time in a real river.

NewsMelting glaciers may release hidden antibiotic resistance into vital water sources
Researchers report that glaciers act as long-term reservoirs of antibiotic resistance genes. Once released by glacier melt, these genes can enter rivers, lakes, and ecosystems that supply drinking water and support wildlife in polar and high-altitude regions.

NewsWhat causes some people’s gut microbes to produce high alcohol levels?
A study of people with a rare condition known as auto-brewery syndrome has found a link between gut microbes and symptoms of intoxication, pointing to new treatment strategies.

NewsVictoria’s Secret grant backs cutting-edge ovarian cancer research
Promising ovarian cancer research by Melanie Rutkowski, PhD, at the University of Virginia Comprehensive Cancer Center has won $700,000 in support from the Victoria’s Secret Global Fund for Women’s Cancers in partnership with Pelotonia and AACR, the American Association for Cancer Research.

NewsA high-protein diet can defeat cholera infection
A new study has found that diets high in casein, the main protein in milk and cheese, as well as wheat gluten, could make a dramatic difference in the amount of cholera bacteria able to infect the gut.

NewsA new ally against tooth decay: Arginine offers sweet relief
A new human clinical trial finds arginine can prevent caries due to bacterial plaques by reducing the acidity, altering the plaque structure and reducing harmful bacteria in the plaques.

NewsMicrobes in breast milk help populate infant gut microbiomes
A new study provides one of the most detailed portraits yet of how different combinations of bacteria in human milk contribute to the assembly of infants’ gut microbiomes.
-
NewsBeyond gene scissors: New CRISPR mechanism discovered
Two studies describe how researchers found a novel CRISPR mechanism, Cas12a2, in a family of nucleases that exclusively cleave DNA. In contrast, Cas12a2 was able to broadly cleave both RNA and DNA.

NewsWhooping cough vaccination for pregnant women strengthens babies’ immune system
Vaccinating women during pregnancy leads to the transfer of antibodies to their newborns. These antibodies were detected not only in blood, but also in the nasal mucosa, the site where whooping cough bacteria enter the body.

NewsNew research decodes the bacterial “zip code” of colorectal cancer for prediction and survival
A recent study shows that bacteria living inside colorectal tumors form distinct ecosystems that are closely linked to how the disease progression and patient outcomes.

NewsCooperation: A costly affair in bacterial social behaviour?
A new study reveals that population bottlenecks can fundamentally reshape how cooperation evolves and persists in complex microbial societies. Researchers explored how repeated bottlenecks affect cooperative traits of Myxococcus xanthus, a model social bacterium.

NewsCholera vaccine completes phase 1 trial
A clinical trial shows promising results for PanChol, a single-dose oral vaccine aimed at the up to 4 million annual cholera cases worldwide.

NewsSub-lethal water disinfection may accelerate the spread of antibiotic resistance
A new study reveals that environmental stressors do not merely kill bacteria; they can also prime surviving cells to take up resistance genes more efficiently, raising concerns about how antibiotic-resistant bacteria may spread in aquatic environments.
-
NewsSome antibodies outmaneuver germs from sticking to cells
Researchers have uncovered several new mechanisms by which antibodies block E. coli bacteria that cause urinary tract infections from attaching to bladder cells. Once E. coli bacteria get a strong grip, they can be difficult to flush out.

NewsRibosomal engineering creates ‘super-probiotic’ bacteria
Using ribosome engineering (RE), researchers introduced mutations affecting the protein synthesis mechanism of probiotic Lacticaseibacillus rhamnosus GG (LGG). These mutant LGGs exhibit altered surface protein expression, including increased presentation of so-called “moonlighting proteins.”

NewsCRISPR discovery could lead to single diagnostic test for COVID, flu, RSV
Researchers report newly discovered details about the Cas12a3 immune system that precisely targets transfer RNA in invading pathogens, without destroying host cells.
