Study: Antibiotic resistance is increasing in Shiga toxin-producing E. coli

Resistance to antimicrobial agents is rising among human infections with Escherichia coli bacteria that produce the Shiga toxin, according to a study analyzing data from nearly 2,000 infections in the United States between 2010 and 2021.

Antibiotic by-products in waterways continue promoting bacterial resistance

Antibiotics continue to drive resistance to bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first time.

Home sewage overflows expose residents to dangerous drug-resistant bacteria

A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat.

Modified culture medium speeds up detection of antibiotic resistance

A critical problem with treating Clostridioides difficile infections is the possibility that the pathogen develops resistance to fidaxomicin, an antibiotic often prescribed as a first-line treatment.

New manufacturing platform produces targeted mixtures of beneficial gut bacteria

Researchers at the Icahn School of Medicine at Mount Sinai have developed a new manufacturing platform for producing targeted mixtures of beneficial gut bacteria, an approach that could help expand access to microbiome-based therapies for patients with recurrent Clostridioides difficile (C. difficile) infection.

New antibiotic kills drug-resistant bacteria by targeting a previously unknown vulnerability

Researchers at McMaster University have discovered a new antibiotic that kills some of the world's most dangerous and drug-resistant bacteria - and does so by targeting a previously unknown vulnerability, opening the door to an entirely new class of treatments.

Giving antibiotics for throat infections overrates their power against sepsis

Antibiotics for sore throats have hardly any preventive effect against serious streptococcal infections in the population, according to a study from the University of Gothenburg.

Gladstone receives NIAID grant to establish the Center for PhAIge Therapy

When a bacterial infection stops responding to antibiotics, doctors have few options to treat it. Phages-viruses that naturally infect and kill bacteria-have long intrigued clinicians as a potential weapon against these infections.

Southwest Research Institute evaluates NASA's medication handling practices

Southwest Research Institute evaluated NASA's medication handling practices, which currently call for removing medications from their original packaging and storing them in resealable plastic bags.

Post-discharge oral antibiotics show no benefit for pediatric appendicitis

Acute appendicitis is one of the most common surgical emergencies among children, and complicated acute appendicitis (CAA), including perforated or gangrenous disease, carries a higher risk of infection and longer hospitalization.

Teclistamab delivers deeper responses in relapsed myeloma patients

Patients with relapsed multiple myeloma treated with the immunotherapy teclistamab lived significantly longer and remained in remission far longer than those receiving standard therapies, according to results from a major international phase 3 clinical trial published in The New England Journal of Medicine and presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting.

New approach helps design better antibiotics to fight drug-resistant infections

A new way of designing antibiotics could support the discovery of new treatments for drug-resistant infections.

Gut microbiota may determine severity of life-threatening sepsis infections

Why do some people recover easily from bacterial infections while others rapidly deteriorate into life-threatening sepsis? According to a new study, the answer may lie not only in the invading pathogen itself, but also in the microorganisms already living inside the gut.

Surface acids found crucial for bacterial shape and growth

Researchers have discovered how acids on the surface of bacteria give these microscopic organisms their characteristic "rod" shape-by keeping an enzyme at bay that would otherwise turn the cylindrical cells into shape-shifting blobs.

Rattlesnakes show higher vulnerability to fungal and parasitic infections

Snakes are threatened with extinction in many places around the globe. Disease, often caused by parasites or fungi, is thought to be one of the key factors alongside habitat destruction.

New AI model detects hidden antibiotic resistance genes beyond standard databases

resLens uses genomic language models to detect antibiotic resistance genes from DNA sequences, performing especially well on long-read data and on some ARGs poorly represented in reference databases.

Yoga and meditation show promise for gut health

This systematic review found that yoga and Buddhist meditation were associated with favorable gut microbiota and metabolite profiles in four human studies involving healthy adults. However, because participants largely followed vegetarian or vegan diets and no randomized controlled trials were included, the findings cannot prove that meditation alone reshapes the gut microbiome.
