Phylogenetic characterization of Orientia tsutsugamushi isolated in Taiwan according to the sequence homologies of 56-kDa type-specific antigen genes.
Fourteen strains of Orientia tsutsugamushi isolated in Taiwan were characterized by sequencing 56-kDa type-specific antigen genes and patterns of restriction fragment length polymorphism (RFLP) predicted by a computer program. The strains showed high varieties in sequence homologies and were classified to 10 types by predicted patterns of RFLP. Furthermore, all Taiwan strains were not identical in typing with strains analyzed previously. These results suggest that there are various types of O. tsutsugamushi in Taiwan that are different from those distributed in other countries.
