The paper identifies a seventh RND efflux pump, EefABC, in E. coli phylogroups associated with infection, showing high conservation and distinct structural features compared to known systems.

This study examines how early antibiotic and probiotic treatments affect the gut microbiome and resistome in preterm infants, finding that probiotics reduce antibiotic resistance genes and MDR pathogens but do not eliminate them.

This study identifies Staphylococcus haemolyticus as a common gut colonizer in preterm infants and reveals its role as a reservoir of antibiotic resistance genes through genomic analysis.

This study compares antibiotic resistance and virulence between Acinetobacter lwoffii and A. baumannii, finding A. lwoffii has fewer resistance genes, more DNA defense systems, and reduced ability to develop resistance.
