Adhesion and invasion of PilT+ and PilT MC onto a monolayer of T84 epithelial cells

Phenotype Adhesion at 4 h Adhesion at 9 h
Invasion at 9 h*
Viable cells Viable cells Fixed cells
PilT+ 28.1  ±  1.3 13.6  ±  0.5 3.1  ±  0.4 3.4  ±  0.5

Adhesion is calculated as the ratio of 100 × cell-associated cfu to total cfu. Each value is the mean of three distinct experiments ±SD. ND, not done. 

*

Reported as the log of cell-associated cfu after 60 min of incubation in a medium containing 150 mg/liter of gentamicin. Each value is the mean of at least three different experiments ±SD. 

The nonpiliated strain is clone 12pilE∷Km as described (18).
