Gene copy number of five vector-borne pathogens in canine whole blood samples. Quantitative FRET-PCRs determined the gene copy number of five tick-borne pathogens. The rRNA copy numbers for E. canis (84 ± 71 /per ml whole blood; range 50 ~ 313) were significantly lower than those for H. canis (72,120 ± 260,148), A. platys (370472 ± 659438; range 651 ~ 1534409), and B. canis (35161 ± 61,335; range 72 ~ 199,552). The gltA copy number for R. felis (204 ± 125; range 116 and 292) was not significantly different from the rRNA copy number of the other four tick-borne agents. The Y-axis is shown as logarithmic scale, and the data were shown as average gene copy number (-), mean ± SD (□) and mean ±1.96 × SD (Ι).
