Antibiotic News and Research

RSS

Antibiotics are drugs used to treat infections caused by bacteria and other microorganisms.

Scientists uncover protein switch that turns on leptospirosis virulence

During infection, pathogens must adapt quickly to the conditions to thrive inside the body. A research team at the University of Basel, Switzerland, has uncovered how a key protein switches on the machinery that enables Leptospira pathogens to survive and cause disease.

Bacterial vesicles emerge as powerful tools against antibiotic resistance

Antibiotic resistance is making bacterial infections harder to treat, demanding new therapeutic strategies. A new review highlights bacterial extracellular vesicles (BEVs) as promising nanoscale tools that can kill pathogens, block infection, enhance vaccines, and deliver drugs.

Molecular gatekeepers in bacteria prevent the spread of antibiotic resistance

A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads.

Algeria eliminates trachoma as a public health problem after decades of effort

The World Health Organization (WHO) has validated Algeria as having eliminated trachoma as a public health problem, making it the 10th country in WHO's African Region and the 29th country globally to achieve this significant milestone.

Children with multiple chronic conditions show unique antibiotic exposure patterns

A new study from Boston Children's Hospital found that annual prescription rates increased non-linearly as children's underlying level of medical complexity increased. Frequent antibiotic use has associated risks, including increased likelihood of antibiotic-related complications (e.g., C. difficile) as well as the development of antibiotic resistance. Findings from the study will be presented during the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston.

AI model rapidly designs new antibiotic to fight resistant bacteria

Researchers at McMaster University have developed a new generative artificial intelligence (AI) model capable of drastically speeding up drug discovery - and, in early tests, it has already designed a brand-new antibiotic.

Detailed structure of Vibrio bacteria offers hope for new therapies

Scientists have mapped in unprecedented detail the structure of Vibrio bacteria, which can cause life-threatening infections linked to antibiotic resistance.

High levels of gut bacterial toxin linked to increased lupus nephritis risk

The body's immune reaction to increased levels of a toxic molecule, part of a bacterial species in the human gut, may reveal who is most at risk of developing lupus nephritis, according to a new study led by NYU Langone Health.

Gut microbiome characteristics predict treatment response in IBS-D patients

In a new study published in Clinical Gastroenterology and Hepatology, the low FODMAP diet and the antibiotic rifaximin provided similar and significant relief for patients with irritable bowel syndrome with diarrhea (IBS-D).

Rapid blood infection test fails to improve survival

Rapid antimicrobial susceptibility testing for gram-negative blood infections shows no improvement in clinical outcomes compared to standard testing methods.

Scientists develop MIND approach to predict and reshape microbiomes

University of California San Diego researchers have developed a new tool for understanding and modifying any microbiome, including the human microbiome.

New mechanism disables antibiotic resistance and cross-protection in bacteria

A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.

WHO-recommended antibiotics ineffective for many neonatal sepsis cases

A major multi-country study has found that WHO-recommended first-line antibiotics for neonatal sepsis are likely to be effective in only one quarter of infections in low- and middle-income countries (LMICs).

Study finds no benefit of stronger antibiotics for sinusitis

Acute sinusitis leads to more antibiotic prescriptions for U.S. adults than any other condition, but there is no consensus on which antibiotic is preferred for uncomplicated cases.

Newborns carry antibiotic resistance genes within first hours of life

Antibiotic resistance genes (ARGs) – segments of DNA that help bacteria survive the effects of antibiotics – can be present in newborns within the first hours of life, according to research presented at ESCMID Global 2026.

Synthetic biology approach boosts growth of implanted liver tissue

In patients developing end-stage liver disease, the damage has become too severe for the liver's normally extraordinary regenerative capacity to repair or compensate for it. Once this "point of no return" has been reached, the only option is an organ transplant.
