Evolutionary history of the genes for the “survival in fish blood kit”. Molecular phylogenetic analysis of ftbp (A) and fpcrp (B) was performed using the maximum likelihood method based on the Tamura 3-parameter model [47]. The tree is drawn to scale, with branch lengths measured as the number of substitutions per site. The main host (tilapia or eel) is shown in each tree.
