YprA-family helicases provide the missing link between diverse prokaryotic immune systems

Image
Highlights • YprA-family helicases are a central hub in the prokaryotic defense system network • YprA phylogeny analysis identifies a distinct class of defense systems called ARMADA • ARMADA protects bacteria against diverse phages and synergizes with Druantia III • ARMADA, Druantia III, and Zorya II co-occur in phage-like integrated elements

Association between secondhand smoke exposure and ocular microbiome changes in children

Image
Highlights • Secondhand smoke (SHS) exposure significantly alters the ocular surface microbiome (OSM) in children aged 3–18 years. • Microbial diversity is significantly reduced on ocular surface in SHS-exposed children. • Beneficial commensal taxa are depleted in SHS-exposed children. • Environmental stress-related metabolic pathways and immune-related pathways are significantly altered in SHS-exposed children.

Mucin modulates phage infection dynamics and biofilm formation in enteropathogenic Yersinia enterocolitica

Image
Highlights • Mucin modulates phage-host dynamics in Yersinia enterocolitica. • Temperature and nutrient availability further shape phage infection outcomes. • Bacterial pre-exposure to mucin leads to 2-log increase in phage titers. • Mucin supplementation reduces biofilm formation in all tested conditions. • Phage-resistant variants carry mutations in metabolism, quorum sensing, antimicrobial resistance genes.
