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

Existing drug helps bladder cells destroy hidden urinary tract infections

Urinary tract infections, or UTIs, are among the most common bacterial infections, caused mostly by the uropathogenic bacterium Escherichia coli. But even after antibiotic treatment, a large number of patients experience another UTI.

Kansas researchers secure NIH funding to fight antibiotic resistance

As antibiotic resistance makes everyday infections tougher to treat and emerging pathogens drive challenging infectious-disease outbreaks, researchers in Kansas from multiple disciplines and institutions are teaming up to target pathogens and overcome antibiotic resistance.

Why are more younger adults in the Eastern Mediterranean facing colorectal cancer?

A 22-country analysis of modeled GLOBOCAN 2022 data found 15,381 early-onset colorectal cancer cases and 6,965 related deaths across the WHO Eastern Mediterranean Region, with substantial differences between countries and comparatively high mortality. Projections suggest that annual case and death counts could rise markedly by 2050, largely due to demographic change, while the findings support screening and detection strategies tailored to local resources and disease burden.

A child's gut microbiome may offer early clues to type 1 diabetes risk

Researchers tracking 887 children at high genetic risk of type 1 diabetes identified three distinct patterns of gut microbiome maturation during early childhood. One pattern was associated with substantially higher risk of islet autoantibody seroconversion or type 1 diabetes, while host genetic background altered the risk associated with another pattern.

Could a parent’s hospital job shape a child’s nasal microbiome?

A pilot study of 37 families found that children with healthcare-worker parents had lower nasal microbial diversity, with the largest differences among children whose two parents worked in healthcare. Porphyromonas was significantly less abundant, while Neisseria showed a similar non-significant pattern, but the cross-sectional study cannot establish causality or determine whether these microbiota differences affect health.

Wearable microneedle patch tracks antibiotic levels in real time

A wearable patch with microneedles coated in DNA molecules tracks levels of antibiotics in the body in real time.

New national guidelines developed to improve sepsis-related care

A UVA Health doctor and other leading national experts have developed important new guidelines to improve care for patients who develop sepsis, a dangerous full-body infection that kills at least 350,000 Americans every year.

Researchers mine cobra toxins to uncover a membrane-disrupting antimicrobial peptide

Researchers combined toxin sequence mining with machine learning and deep-learning prediction tools to identify and experimentally test 14 antimicrobial peptide candidates derived from cobra cardiotoxins. Most candidates showed limited antibacterial potency, while CTX-p5 displayed moderate membrane-disrupting activity, revealing both the potential and current limitations of computationally guided venom peptide discovery.

Can AI find drugs to fight infection?

Streptococcus pneumoniae is a bacterial pathogen that causes life-threatening infections, including pneumonia and meningitis.

Genetically modified bacteria create protective shield against Salmonella attacks

The mammalian gut microbiome is teeming with a delicate balance of bacteria and the viruses that keep them in check, called bacteriophages, or phages.

C. diff uses dual-threat sensing system to survive gut stress

The pathogen Clostridioides difficile (C. diff) - a leading cause of hospital-acquired infections - must contend with a variety of threats inside the harsh environment of the gut to survive and grow.

River-type drinking water sources generally carry higher antibiotic resistance risks

Antibiotic resistance is increasingly recognized as a major public health and environmental challenge, yet the risks are not evenly distributed across aquatic environments.

Helicobacter pylori exposure linked to one in five cases of bowel cancer

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, published in the open access journal eGastroenterology.

Scientists discover new mechanism for bacterial fosfomycin resistance

Bacteria can survive antibiotics in several ways, including by pumping the drugs out of their cells before they can take effect.

The vaginal microbiome may be an overlooked reservoir of antibiotic resistance

Researchers analyzed 1,957 vaginal metagenomic samples from 1,547 pregnant women and found that bacterial community structure was strongly associated with the diversity and distribution of clinically relevant antibiotic resistance genes. Lactobacillus crispatus-dominated communities carried comparatively few acquired resistance genes, while L. iners-dominated and anaerobe-rich communities showed greater resistance diversity, with PPROM associated with broader predicted resistance profiles among ARG-positive samples.

Microplastics transport toxins and antibiotic resistance across ecosystems

Microplastics are often viewed as pollutants in their own right, but their environmental impact may extend far beyond the plastic particles themselves.

Scientists capture how bacteria build their protective antibiotic-resistant barriers

Gram-negative bacteria are responsible for causing several infections that are hard to treat, owing to their high resistance to antibiotics.

Lab-grown micro bladder helps explain why urinary tract infections return

A lab-grown micro bladder may explain why urinary tract infections (UTIs) return so frequently, according to a study led by researchers at UCL, the University of Oxford and the University of Leicester.

Genetic marker links popular seizure drug to life-threatening reaction

A genetic marker already used to flag risk of a life-threatening reaction to the antibiotic vancomycin also identifies patients at risk of that reaction to lamotrigine - and it is missing from the gene panels clinicians order before prescribing the drug, Vanderbilt Health-led researchers report Sept. 2 in JAMA Network Open.
