TaqManPCR-positiveDNAsamples were used for specific identification of A. phagocytophilum, A. platys, E. chaffeensis, E. ewingii, E. canis, and E. muris by nested and single-tube conventional PCRs, as previously described, using species-specific primers (Table 1). The 16S rRNA gene fragment of A. phagocytophilum was amplified by a nested PCR assay according to the procedure of Barlough et al. (6). PCR for E. muris was performed using primers CAN M61f and MUR SPR1, targeting the gltA gene of E. muris (21). The primer sets for nested PCRs for A. platys, E. chaffeensis, E. ewingii, and E. canis DNAs were derived from the 16S rRNA gene sequences, with the same pair of outer primers and different sets of inner primers (36, 37). The oligonucleotide sequences for each pair of genus- and species-specific primers are shown in Table 1. PCR amplification of genomic DNAs of R. rickettsii, R. japonica, and Borrelia burg
dorferi was performed with species-specific primers (Table 1) as previously described (16, 42, 52).
