Mannitol flux rates and their corresponding TEER values in Caco-2 cell monolayers incubated with various bacterial strains.

	Control	Ecf	ETEC	EPEC	Sampling time
TEER (Ohmcm^2)	327 ± 68^a	359 ± 89^a	35 ± 38^b	135 ± 116^b	10 h
Mannitol flux (nmolcm^−2h^−1)	11 ± 3.9^a	11.4 ± 7.2^a	86.7 ± 26.6^b	108 ± 25.9^b
TEER∣ Mannitol	8∣5	9∣6	9∣6	7∣5

Bacterial strains: Caco-2 cells were incubated with E. faecium (Ecf), ETEC, or EPEC for 10 h (mean ± standard deviation, variance analysis, post hoc Scheffe test, , different letters indicate significant differences between incubation groups); = cell culture inserts.
