New strategy restores vancomycin effectiveness against resistant bacteria

Antibiotic resistance is one of the most urgent threats to global health, linked to an estimated 4.7 million deaths worldwide in 2019 alone.

New pico-calorimeter detects antibiotic resistance via direct heat traces

When living cells grow, divide, or respond to drugs, they give off tiny amounts of heat that offer information about what the cells are doing. But since these heat signals are so vanishingly small, they have been traditionally impossible to measure directly.

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).

European report: Antimicrobial resistance remains widespread in foodborne bacteria

Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC).

Sub-lethal water disinfection can unintentionally boost the spread of antibiotic resistance

The study reveals that environmental stressors do not merely kill bacteria; they can also prime surviving cells to take up resistance genes more efficiently, raising concerns about how antibiotic-resistant bacteria may spread in aquatic environments.

Early life gut microbiome crucial for immune system development

Antibiotics are powerful treatments that have saved countless lives over the course of decades. New findings from Scripps Research have identified a way to preserve healthy immune development even when infants need antibiotic treatment.

Tiny antibiotic traces found to greatly accelerate resistance spread

Antibiotic resistance is widely recognized as one of the most urgent public health challenges of the twenty first century.

Chlorinated compounds from slime mold show strong antibacterial activity

The cellular slime mold Dictyostelium discoideum is a soil microbe that produces diverse natural products with potential antibiotic activity.

Early antibiotic exposure weakens infant immune development

A new study led by researchers at the University of Rochester Medical Center (URMC) found that early-life exposure to antibiotics can impair an infant's developing immune system, and that a naturally occurring metabolite may hold the key to reversing that damage.

Ionophore use in farming drives global spread of antibiotic resistance genes, study finds

Researchers identified the widespread presence of the ionophore resistance genes narA and narB in over 2,400 bacterial isolates across 51 countries. These genes are often genetically linked to resistance against critically important human antibiotics, raising concerns over agricultural practices and global antimicrobial resistance.

Antibiotic use predicts microbiota dysbiosis in preterm infants

Antibiotic use in preterm infants is linked to gut microbiome changes, increasing susceptibility to infections and impacting long-term health outcomes.

Study reveals mechanisms behind antibiotic-related immune disruptions in infants

In 2017, scientists at Cincinnati Children's revealed that using antibiotics to protect newborns from dangerous infections often comes with a long-term consequence-a permanently underdeveloped immune system that can make children prone to poor outcomes from future lung infections.

Energy drain from antibiotics spurs bacteria to resist treatment faster

Antibiotics are supposed to wipe out bacteria, yet the drugs can sometimes hand microbes an unexpected advantage.

How soy and gut microbes alter cancer treatment results

Researchers have discovered that plant-derived phytochemicals and their gut microbiome metabolites control the effectiveness of PI3K inhibitors in cancer therapy. The study reveals that dietary components, especially soy compounds processed by gut bacteria, can alter drug metabolism and impact treatment outcomes.

Rising antibiotic resistance threatens UTI treatment in Malawi

A growing resistance to antibiotics is complicating the treatment of urinary tract infections (UTIs) in Malawi, with new research revealing that nearly half of women presenting with symptoms at a major referral hospital had infections resistant to multiple drugs.
