NewsHeatwaves inhibit antibiotic resistance in soils - but at a price
Heatwaves temporarily reduce the amount of resistance genes in the soil, but heat and droughts are also causing significant damage to soils and ecosystems. The temporary dip in resistance therefore does not mean that the health risks from antibiotic resistance disappear.

NewsProbiotic use surges - but microbiome-supportive food consumption stagnates
New research finds that probiotic supplement use has surged in the United States, while the consumption of microbiome-supportive foods has remained virtually unchanged. According to a study published in Clinical Gastroenterology and Hepatology, the consumption of probiotic supplements increased 287% among adults from 2009-2023 and 786% among ...

NewsToxic tail: Biologists find a hidden weak spot in how bacteria build the tails they use to move
New research has uncovered a previously unknown vulnerability in how bacteria build the whip-like tails they use to move. Building these tails can put stress on the protective wall surrounding a bacterial cell, and uncovered systems bacteria use to keep that stress from becoming destructive.

NewsHelicobacter pylori exposure may be linked to more than 1 in 5 bowel cancer cases worldwide
Exposure to the stomach microbe Helicobacter pylori may be associated with more than 1 in 5 cases of bowel cancer worldwide, suggests an exploratory risk attribution study - and those born in more recent decades may be more at risk of the disease after exposure.

NewsBacterial trial fails to demonstrate early asthma prevention - prompting rethink of 'hygiene hypothesis'
A national clinical trial has found that treating young children with an oral bacterial extract did not reduce the risk of severe wheezing and respiratory illnesses that can precede asthma, potentially prompting researchers to rethink aspects of the hygiene hypothesis.

NewsCommonly used cancer drugs boost MRSA antibiotics – new research
Scientists tested five anti-cancer drugs and revealed that four of them helped penicillin-type antibiotics to kill MRSA. These drugs interfere with the bacteria’s ability to make DNA, making the bacteria more vulnerable to the antibiotics.

NewsResearch explores why strep throat can linger, even after treatment with antibiotics
Streptococcal sore throat can linger even after treatment, turning otherwise healthy children into carriers. Using whole genome sequencing, researchers hope to discover why.

NewsRiver drinking water sources may face greater antibiotic resistance risks than reservoirs, study finds
A basin-wide study of 13 drinking water sources in China’s Poyang Lake region shows that water source type can strongly shape the occurrence and spread of antibiotics, antibiotic resistance genes, and resistant bacteria.

NewsMember Q&A: Harta Wedari on how AMI has opened up new opportunities and communities
Dr Ni Luh Putu Harta Wedari, a medical doctor and Clinical Microbiology Specialist from Bali, Indonesia reveals how engaging with AMI has expanded her international network and unveiled new opportunities.

NewsSmall bowel microbiome offers clues to women’s health
A new study has identified differences in the makeup and organization of the small bowel microbiome between women and men. One intriguing finding was a bacterial community containing Granulicatella, found only in women.

NewsA fourth T6SS in clinical Pseudomonas aeruginosa deploys the pore-forming effector TseMt
The hospital-associated pathogen Pseudomonas aeruginosa has type VI secretion systems (T6SSs). Most reference strains encode three T6SSs, but comparative genomics has identified an additional H4-T6SS in a subset of clinical isolates.

NewsMeningitis, hangover or freshers’ flu? Don’t dismiss serious symptoms
Students heading into freshers’ week are being warned not to assume a headache, vomiting or feeling wiped out is simply the result of a heavy night or the dreaded “freshers’ flu”. 246,089 doses of the MenB vaccine were administered to young people in England between 20 July and 31 August.

NewsBacteria in classroom dust associated with reduced lung function in children
Common bacteria found in classroom dust are associated with reduced lung function in children according to new research, Children in classrooms with higher levels of Streptomyces had a 0.08 litres lower forced vital capacity (FVC).

NewsBacteria can make testosterone. What could that mean for prostate cancer?
Scientists have identified an unexpected participant in androgen chemistry: a bacterium from the human urinary tract that can convert the steroid precursor DHEA into testosterone under laboratory conditions. It reveals a previously unknown microbial route to a hormone that is central to prostate biology.

NewsResearchers find C. difficile colonization in infants reshapes gut development
Practically since its discovery, the highly contagious bacterium Clostridioides difficile has been reported to not cause symptoms in infants. But new findings suggest that the bacterium can reshape the developing infant gut and may have long-term consequences.

NewsScientists discover link between gut bacteria and severe liver disease
Researchers have identified what may potentially be a missing link between specific activities in gut bacteria and the liver disease primary sclerosing cholangitis: the metabolite ImP, a molecule formed when certain gut bacteria break down dietary components.

NewsWhat happens when a shoreline scavenger consumes microplastics?
Researchers report on what happens when wharf roaches, a common shoreline scavenger, eat expanded polystyrene (EPS). Analysis of the wharf roach gut microbiome showed little change, but several rare microbes were found only in the EPS-fed specimens.

NewsInternational award supports research into fern-microbe symbiosis
Dr Sophie de Vries will combine evolutionary genomics with experiments that pair ferns and different microbes, to investigate how plants fight off “foes” (diseases) at the same time as supporting their beneficial “friendships” (bacterial partners).

NewsMXene-based hydrogel disrupt bacterial biofilms and reprogram immune cell metabolism to reverse bone resorption in periodontitis
Researchers have developed an injectable MXene-based composite hydrogel (GQM) for the treatment of periodontitis. The hydrogel consists of oxidized gellan gum (OG), quaternized chitosan (QCS), and magnesium-tannic acid modified MXene nanosheets (MTA-Mg).
