Molecular analysis reveals characteristics of Orientia tsutsugamushi in patients with scrub typhus, indicating relationships with regional strains.
We performed molecular characterization of Orientia tsutsugamushi on DNA sequences from 5 patients from Bhutan with scrub typhus. In the 56 kDa gene, all isolates aligned with those from other Asia countries, including Nepal, India, Thailand, and Taiwan. High serum IgM titers correlated with PCR positivity in acutely ill patients.
