This study identifies genetic factors controlling Group 3 K96 capsule synthesis in ExPEC strain M12, showing its role in complement resistance and revealing phase-variable control and OxyR-dependent regulation.

This study identifies opposing roles of iron transport systems in gallium tolerance in extraintestinal pathogenic E. coli using TnSeq and gene knockouts.

The paper uses DNA data and chemical analysis to identify toxic plants in contaminated forage linked to cattle poisoning.

This study identifies accessory genes in mastitis-associated E. coli linked to disease severity and competitive fitness using genome-wide association and in vivo competition assays.
