Table 1. Change in Chlamydia PCR load following vaccination: Percentage (and raw number calculations) of koalas that were C. pecorum positive at 0 months (i.e. at initial vaccination time), and then exhibited changes in their C. percorum load between either 0 and 6 months, or between 0 and 12 months, post vaccination.
Statistically significant effects are shown in bold. Trending (P < 0.1) results indicated with *. Grey shading represents groups with more than expected (based on Pearson residuals) for significant results. The changes are categorized as decreasing, stable or increasing (ΔqPCR ≤ -100, -99–99, and ≥ 100 copies/μL respectively).
