FIG. 8.
Kinetics of 16S RNA transcripts of the GPIC agent following a primary and a challenge urethral infection. Each symbol represents a single animal, and the line represents the mean of the responses of 5 animals at each time point. Filled symbols indicate that the animal was positive for chlamydiae by determination of 16S RNA transcripts. Where the symbols overlap, the total number positive for 16S RNA is given over the total number of animals at each time.
