| genetic typing of the 56-kda type-specific antigen gene of contemporary orientia tsutsugamushi isolates causing human scrub typhus at two sites in north-eastern and western thailand. | orientia tsutsugamushi is the causative agent of scrub typhus, a major cause of febrile illness in the rural areas of southeast asia. twenty-three strains of o. tsutsugamushi were isolated from patients with scrub typhus in north-east (udorn thani province) and western thailand (tak province) between 2003 and 2005. the isolates were characterized by sequencing the entire orf of the 56-kda-type-specific antigen gene, followed by phylogenetic analysis. the majority (15/23) of isolates clustered wi ... | 2008 | 18312580 |
