NewsScientists reveal the first structure of the complete botulinum neurotoxin complex
Researchers have succeeded in creating a molecular blueprint of how one of the world’s most dangerous toxins, botulinum toxin, is structured, stabilised, delivered and released. The research paves the way for more effective drugs.

NewsAlcohol opens the floodgates for bad bacteria
Scientists have found that chronic alcohol use impairs the production of a key cellular signaling protein that helps keep gut bacteria within the gut. Without this guardrail in place, bacteria from the gut can more easily migrate to the liver, exacerbating liver damage caused by alcohol.

NewsStudy exposes sewage contamination locations threatening West Hawai’i coral reefs
New research reveals the extent to which sewage pollution threatens the fragile coral reef ecosystems of West Hawaiʻi Island. Researchers pinpointed locations where high levels of fecal bacteria associated with populated coastal areas are driving worsening contamination.

OpinionSafety and nutritional claims for raw milk
Robert F Kennedy Jr. famously advocates drinking raw milk and promotes its benefits. But how safe is unpasteurised milk? Nicola Holden and Gil Domingue, who sit on Applied Microbiology International’s Food Security Scientific Advisory Group, take a deep dive into the science.

NewsMouth to gut bacteria migration explains why smoking is good for inflamed bowels
Researchers have discovered why smoking tobacco helps people suffering from ulcerative colitis. The study shows that smoking produces metabolites that encourage bacteria from the mouth to grow in the large intestines where they trigger an immune response.

NewsBacteria strains infecting cattle and humans in US are highly similar
Salmonella Dublin, a type of bacteria that primarily infects cattle but some strains also can adapt to infect humans, is increasingly becoming resistant to antibiotics, making it a growing public health threat.

NewsGut bacteria can reveal colorectal cancer
Researchers identified all human gut bacteria to a level of detail that uncovers the physiological importance of the different microbial subgroups. This inventory was then used to detect the presence of colorectal cancer according to the bacteria present in simple stool samples.

NewsColibactin-producing E. coli linked to higher colorectal cancer risk in FAP patients
Researchers have found that patients carrying colibactin-producing Escherichia coli in their colon polyps were more than three times as likely to have a history of colorectal cancer compared to those without the bacterium.

NewsKidney fibrosis linked to molecule made by gut bacteria
A molecule made by bacteria in the gut can hitch a ride to the kidneys, where it sets off a chain reaction of inflammation, scarring and fibrosis — a serious complication of diabetes and a leading cause of kidney failure.

NewsNew AI tool reveals how drugs kill tuberculosis
A new study offers a powerful AI-assisted method for uncovering exactly how TB drugs kill the bacteria, opening the door to smarter treatment combinations that could work faster.
-
NewsArchaea can kill bacteria with new antibacterials
A first look into the molecular defenses of archaea highlights the importance of surveying diverse microbes to discover new types of antimicrobials.

NewsMaternal antibodies in breast milk regulate early immune responses in mouse gut
In mice, maternal antibodies ingested in breast milk in the first week after birth help to regulate immune responses in the newborn gut, according to a new study.
-
NewsResearchers use generative AI to design compounds that can kill drug-resistant bacteria
With help from artificial intelligence, researchers have designed novel antibiotics that can combat two hard-to-treat infections: drug-resistant Neisseria gonorrhoeae and multi-drug-resistant Staphylococcus aureus (MRSA).
-
NewsA microbial DNA signature differentiates two types of cancer in the liver
Researchers have identified a microbial DNA signature in blood plasma that reliably differentiates primary liver cancer from colorectal cancer that has spread to the liver (metastatic colorectal cancer).

News‘Essentiality’ scan reveals microbe’s ‘must-have’ list
Researchers have spent years taking apart one of the world’s simplest microbes, Mycoplasma pneumoniae, piece by piece, and created a detailed list of what molecular parts the living cell can and cannot do without.

News CRISPR-based therapeutics hold potential to combat AMR and cure chronic viral infections, says GlobalData
CRISPR-based therapeutics show potential to combat antimicrobial resistance (AMR) and deliver functional cures for chronic viral infections, says GlobalData, a leading data and analytics company.
-
News‘Controlled evolution’ dramatically boosts pDNA production for biomedical manufacturing
Researchers have controlled the evolution of E. coli bacteria in the lab in order to dramatically increase the amount of plasmid DNA (pDNA) these modified bacteria produce. pDNA is an essential – and expensive – ingredient in many gene therapies.
-
NewsTwo-dose therapy for S. aureus bloodstream infections on par with standard treatment
A clinical trial has found that the outcome of treating complicated Staphylococcus aureus bloodstream infections with two intravenous (IV) doses of the antibiotic dalbavancin seven days apart is just as good as daily IV doses of conventional antibiotics over four to six weeks.

NewsBacterial protein therapy shows promise as first-ever antidote for carbon monoxide poisoning
Researchers have engineered a new molecule that appears promising as an effective antidote for carbon monoxide poisoning with fewer side effects than other molecules currently being tested.

NewsStudy looks for markers that predict risk of severe chlamydia infection
A new study has identified markers that may predict whether a chlamydia infection is likely to ascend into the uterus and endometrium. The work could lead to new diagnostics that can predict a woman’s risk of severe infection.
