So happy to share this! Bacteriocins were first discovered over 100 years ago, but what do they actually do? We look at >1000 bacteriocin plasmids and find links to virulence and antimicrobial resistance, and frequent bacteriocin sharing in Enterobacteriaceae.

New online! Genome sequencing for prevention of health-care-associated bacterial infections
Genome sequencing for prevention of health-care-associated bacterial infections
Nature Reviews Microbiology, Published online: 10 November 2025; doi:10.1038/s41579-025-01254-yMicrobial whole-genome sequencing is an important element of health-care-associated infection (HAI) prevention strategies. Focusing on specific high-priority antibiotic-resistant bacterial pathogens, this Review outlines the epidemiology and microbiology of HAIs and discusses the role of whole-genome sequencing in HAI prevention and surveillance.
