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.

New research reveals wild mice as reservoirs for antibiotic resistance

Antibiotic resistance in humans and farm animals poses a major health challenge. A new study published in the journal 'Nature Communications' reveals that this problem does not stop at hospital doors or farm gates - indeed, antibiotic resistance genes (ARGs) can also be detected in wild animals.

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.

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.

Increasing resistance to key gonorrhea antibiotics raises alarm

The World Health Organization (WHO) warns that gonorrhea, a sexually transmitted infection, is becoming increasingly resistant to antibiotics, according to new data from its Enhanced Gonococcal Antimicrobial Surveillance Programme (EGASP), which monitors the spread of drug-resistant gonorrhea.

Researchers develop a versatile tool for controlling gene activity

Investigators at Weill Cornell Medicine have developed a versatile and non-toxic technology for controlling the activity of any gene in a cell. Such "gene-switch" tools allow scientists to "turn on" or "turn off" a target gene to study how it works, model diseases and design new therapies.

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.

Flies on dairy farms act as hidden carriers of superbugs and zoonotic threats

Researchers used deep metagenomic sequencing to trace zoonotic pathogens and antibiotic resistance genes from cow manure into the guts of muscid flies on a French dairy farm. Findings reveal that flies not only carry but may amplify dangerous microbes, underscoring public health risks.

When old diseases find new ways in: Europe’s latest diphtheria outbreak explained

A large multicountry outbreak of toxigenic Corynebacterium diphtheriae occurred among migrants entering Europe in 2022, driven primarily by cutaneous infections and involving multiple genetic lineages. Despite the unprecedented surge, transmission to resident populations was limited, but rising antimicrobial resistance and delayed treatment highlight ongoing public health risks.

Maternal exposure to metals rewires infants’ gut and resistance genes

Prenatal exposure to trace elements like selenium, copper, and arsenic can significantly alter the infant gut microbiome, metabolism, and antibiotic resistance gene patterns. These changes appear as early as three months and evolve during the first year of life.

Global analysis of antimicrobial resistance in Campylobacter

Announcing a new article publication for Zoonoses journal. The zoonotic pathogen Campylobacter is a major foodborne bacterial species worldwide. The distribution and drivers of antimicrobial resistance (AMR) in global Campylobacter strains remain largely unknown. Therefore, a comprehensive analysis of longitudinal trends and driving factors of AMR in Campylobacter is necessary at a global level.
