FIG. 3.

Interaction of BEC with Ames spores treated with trypsin. Cytochalasin D-treated BEC were incubated with either untreated Ames spores or trypsin-treated spores for 1 h at an MOI of 23 to 26 spores for one BEC. Following this incubation, the cells were washed and lysed and the bacteria were plated upon LB agar plates. The percent recovery of spores was determined, and the difference in the number of spores (with or without trypsin treatment) associated with the BEC was significant (P = 0.0003). Error bars represent the standard errors of the means from triplicate independent experiments.
