Fig. 4. Efficiency of invasion and plaque formation by PruΔhpt and 52F11 strains.

Fig. 4

A. Equal numbers of PruΔhpt and 52F11 strains were allowed to invade HFFs for 15 or 60 minutes. The data was expressed as the ratio of the total number of invaded 52F11 parasites divided by the total number of invaded PruΔhpt parasites, with a ratio of 1 thus indicating no difference in invasion efficiency between the two strains. Data bars represent the mean ratio values for 3 independent experiments and the error bars represent the standard deviation. B. Equal numbers of PruΔhpt and 52F11 strains were allowed to invade HFFs and propagate for 6 days, at which point the cells were fixed, stained, and the total number of plaques per well of a 24-well plate was counted. Data bars represent the mean total number of plaques for 3 independent experiments and the error bars indicate the standard deviation.
