Fig. 4From: Whole-genome sequencing-based phylogeny, antibiotic resistance, and invasive phenotype of Escherichia coli strains colonizing the cervix of women in preterm laborEpithelial invasion comparisons of cervical colonization and invasive neonatal E. coli isolates. Legend: The invasion capacity of E. coli cervical isolates and neonatal bacteremia isolates was compared using an intestinal epithelial cell invasion model in-vitro [23]. Cervical colonization isolates most closely related to neonatal bacteremia isolates at the phylogenetic level (SCBcol-1, SCBcol-5, and SCBcol-6) showed the greatest invasion capacity as a group, as compared to the group of least phylogenetically related colonization isolates (P<0.03, one way ANOVA)Back to article page
