Sequence alignments of the 18S ribosomal RNA genes derived from Babesia vogeli and Hepatozoon canis (a) and the 16S ribosomal RNA genes from Ehrlichia canis andAnaplasma platys (b). The dotted arrows indicate the positions of the forward primers and biotinylated reverse primers for template amplification. The solid arrows indicatethe positions of the sequencing primers. The rectangles indicate the regions of determination. The asterisks indicate the nucleotide positions used for the discriminations
