From: Virulence and transcriptome profile of multidrug-resistant Escherichia coli from chicken
In vitro virulence assay of five E. coli isolates along with ATCC 25922 in Caco-2 cells. (a) Number of adherent and internalized bacteria. The results are presented as log10 of the mean ± standard deviation (SD) CFU/mL of three independent repeats and compared to E. coli ATCC 25922. (b) Intracellular survival rate of E. coli isolates at different time intervals. The results are presented as log10 CFU/mL mean ± SD of survival rate. Asterisk (*) represents statistical significance (P ≤ 0.05) using two-tailed t-test.
