TER across Multilayers of Rabbit Corneal Epithelial Cells Infected with Wild-type P. aeruginosa Strain PAK

	Mean (±SD) TER Reading (Ω/cm2) at Postinoculation Time Points
	0 h	1 h	2 h	3 h	4 h	5 h	6 h	7 h	8 h
Wild-type PAK*	135 ± 1	132 ± 2	131 ± 2	130 ± 2	130 ± 2	127 ± 2	125 ± 1	123 ± 2	121 ± 2
No bacteria control	133 ± 2	132 ± 2	131 ± 3	130 ± 2	129 ± 2	128 ± 3	128 ± 3	124 ± 2	123 ± 2
EGTA control†	104 ± 2	100 ± 2	99 ± 3	100 ± 1	99 ± 1	99 ± 1	99 ± 1	92 ± 2	97 ± 2

Layers of infected cells showed TER values similar to those of uninfected (HBSS-inoculated) cells throughout the 8-hour traversal assay. Each remained significantly higher than in controls treated with 100 mM EGTA (P < 0.05, t-test).

^*No significant difference versus uninfected cells at each time point (P < 0.05, t-test).

^†Similar to baseline control (submerged filter without epithelial cells).
