Obesity sharply increases hospitalisation risk from infections, global analysis shows

Adult obesity is associated with a substantially higher risk of severe hospital-treated or fatal infections across multiple pathogens, with risk increasing as obesity severity rises. Global modelling suggests roughly one in ten infection-related deaths worldwide may be attributable to adult obesity, although causality cannot be confirmed.

Modified peptides show promise against tuberculosis bacteria

Antibiotic treatments are losing effectiveness against a range of common bacterial pathogens, including E. coli, K. pneumoniae, Salmonella and Acinetobacter, according to a warning issued by the World Health Organization last October.

Genetic variants in 11 regions of human genome influence the gut microbiome

In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there.

Distinct microbial signature identified in pediatric Crohn's disease

NYU researchers have found a "microbial signature" of pediatric Crohn's disease that differs from the makeup of gut bacteria in children with other gastrointestinal conditions, with Crohn's patients harboring more pro-inflammatory bacteria and less protective bacteria.

New AI model eliminates false positives in food testing

Researchers have significantly enhanced an artificial intelligence tool used to rapidly detect bacterial contamination in food by eliminating misclassifications of food debris that looks like bacteria.

Engineered wax moths offer ethical alternative to rodents used in research

A scientific breakthrough not only promises faster testing for antimicrobial resistance, but also an ethical solution to the controversial issue of using rodents in research.

Obesity drives one in ten infectious disease deaths

Just over one in 10 deaths from a wide range of infectious diseases can be attributed to obesity worldwide, finds a major new study led by a University College London (UCL) researcher.

Study identifies link between gut bacteria and deterioration of the brain in ALS, dementia

A significant discovery by Case Western Reserve University researchers could change how doctors treat two of the most devastating neurodegenerative diseases.

Early tuberculosis treatment reduces sepsis deaths in HIV patients

Sepsis is a leading global cause of hospital deaths, occurring when the body's response to infection damages tissue and causes organs to fail. Africa bears the world's highest burden of sepsis, with an estimated 48 million cases each year leading to about 11 million deaths.

CRISPR gene-drive technology reverses antibiotic resistance in bacteria

Antibiotic resistance (AR) has steadily accelerated in recent years to become a global health crisis. As deadly bacteria evolve new ways to elude drug treatments for a variety of illnesses, a growing number of "superbugs" have emerged, ramping up estimates of more than 10 million worldwide deaths per year by 2050.

New analysis reveals hidden complexity in the vaginal microbiome

For decades, gynecological tests have relied on a simplified view of the vaginal microbiome, categorizing bacteria as either "good" or "bad."

Climate change is accelerating antibiotic resistance across the Western Pacific

Urgent action is needed as climate change fuels antibiotic resistance in the Western Pacific, threatening health and highlighting socioeconomic vulnerabilities.

Gut microbial butyrate enhances mucosal vaccine antibody responses

A research team from POSTECH and ImmunoBiome in Korea, led by Professor Sin-Hyeog Im, has uncovered a new mechanism showing how butyrate-a short-chain fatty acid produced by gut commensal bacteria-enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.

Australian researchers develop a new way to target deadly, drug-resistant bacteria

Australian researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognize a sugar found only on bacterial cells – an advance that could underpin a new generation of immunotherapies for multidrug resistant hospital-acquired infections.
