TABLE 3.

Effect of temperature, cycloheximide, and cytochalasin D treatment on bacterial invasion of CASMC

Strainb	% Inhibition of invasiona:
	At 4°C	With cycloheximidec	With cytochalasin Dd
P. gingivalis 381	99.92	99.99	97.5
P. gingivalis W50	97.6	99.7	99.8
P. intermedia 17	77.8	99.7	99.7
E. corrodens 23834	2.0	97.3	96.0

^aValues represent the percentage of invasion that diminished in the presence of inhibitors compared to invasion without inhibitors present. 

^bP. intermedia 25611 was not included, since there was no invasion to inhibit. 

^cCycloheximide (1 mg/ml) was preincubated with CASMC for 4 h and was present during the assay. 

^dCytochalasin D (5 μg/ml) was preincubated with CASMC for 0.5 h and was present during the assay.
