The P. ovis tritonymph stage is most closely associated with “fed” mite transcriptional changes. Six-way Venn/Euler diagram demonstrating gene conservation between P. ovis life-cycle stages. Each arm consists of the genes from the stage-specific expression clusters shown in Table 1. (Larvae, Protonymph, Tritonymph, Adult Females and Adult Males and genes whose expression was significantly upregulated in “fed” P. ovis mites (“Fed” Mites) compared to “starved” mites)
