FIG 1 

SP stimulates Transwell migration of piliated N. gonorrhoeae. Transwells were seeded with parental (FA1090), T4P mutant (∆pilE), or pilus retraction mutant (pilT::erm) strains. The mean number of bacteria ± standard deviation (SD) that cross the Transwell barrier after exposure to SP (1:20) relative to the number of bacteria in RPMI 1640 that cross the barrier is reported for the entire population or just piliated bacteria (P+). Values that are significantly different (P < 0.01) from the value for the parent strain by the two-sample t test are indicated by an asterisk.
