[Detection of Rickettsia tsutsugamushi DNA from chiggers by polymerase chain reaction].
Polymerase chain reaction was employed to detect Rickettsia tsutsugamushi DNA from chiggers for the first time. Both adults and larvae were tested. The positive rate of experimentally infected adults was 92.9%. It suggests that PCR is a rapid and sensitive assay for epidemiological study of scrub typhus.
