Metagenomic next-generation sequencing helped diagnose scrub typhus without eschar: A case report

Blog Article

Background: Scrub typhus is caused by Orientia tsutsugamushi.Clinical manifestations include fever, rash, eschar at the bite site, and other non-specific flu-like symptoms.The eschar is a dark, scab-like area at the bite site, and is the typical lesions that prompts a diagnosis of O.

tsutsugamushi.Without eschar lesions, it is difficult to identify scrub typhus.However, metagenomic next-generation sequencing (mNGS) can be used to identify infections, and this novel method may help improve clinical diagnosis.

Case hbl5266ca presentation: Here, we report a case of scrub typhus in a 51-year-old woman who presented to the emergency department with a week-long fever from voyage et cie discount code an unknown cause.We used mNGS to search for an infectious etiology, and the mNGS suggested O.tsutsugamushi, which was unexpectedly detected.

Discussion and conclusion: This study suggests that mNGS may be a useful diagnostic tool to identify clinical, causative pathogens in fever, particular ones with atypical features.Keywords: Next-generation sequencing, Orientia tsutsugamushi, Fever, Eschars.
