    A: Variation of partial LSU rDNA sequence of Halicephalobus gingivalis JapanHT4677 relative to other isolates. The alignment was performed using ClustalW (Chenna et al., 2003). The asterisks indicate matched nucleotides, and bars mark gaps between the sequences. The two different sequences (JapanHT4677a, JapanHT4677b) determined in the present study are underlined; B: MP tree showing the phylogenetic relationship of H. gingivalis isolated from a horse in Ishikawa Prefecture, Japan, with Halicephalobus isolates and outgroups based on partial LSU rDNA gene sequences (tree length = 920, consistency index = 0.8565, retention index = 0.7376, rescaled consistency index = 0.6317). Multiple-sequence alignment was created with 15.0 gap-opening penalties and 6.66 gap-extension penalties using ClustalX version 1.81 (Thompson et al., 1997). Phylogenetic analysis was performed using methods in PAUP 4.0 beta Version 10 (Swofford, 1998). The bootstrap values evaluated by bootstrap resampling (1000 replicates) are shown above internal nodes. Four outgroup species were selected according to Nadler et al. (2003). The two different sequences (JapanHT4677a, JapanHT4677b) that were determined in the present study are underlined. JapanMA28826 is the H. gingivalis isolate from Ibaraki, Japan (Akagami et al., 2007). Other H. gingivalis sequences were from Nadler et al. (2003): Tenn2, TN, USA; Tenn1, TN, USA; SAN100, Guelph, ON, Canada; South Pacific, CA, USA; JB128, CA, USA; JB043, Neustadt, Germany.
