Figure 1From: Invasiveness as a putative additional virulence mechanism of some atypical Enteropathogenic Escherichia colistrains with different uncommon intimin typesInvasion of epithelial cells by aEPEC and tEPEC strains. A) Percent of invasion in HeLa cells. B) Percent of invasion in T84 cells. Monolayers were infected for 6 h (aEPEC) and 3 h (tEPEC). Results of percent invasion are expressed as the percentage of cell associated bacteria that resisted killing by gentamicin and are the means ± standard error from at least three independent experiments in duplicate wells. *significantly more invasive than prototype tEPEC E2348/69 (P < 0.05 by an unpaired, two-tailed t test).Back to article page
