Scrub typhus causes

Causes

Scrub typhus or Bush typhus is a form of typhus caused by the intracellular parasite Orientia tsutsugamushi, a Gram-negative α-proteobacterium of family Rickettsiaceae first isolated and identified in 1930 in Japan.^[1]^[2]

Scrub typhus is transmitted by some species of trombiculid mites (“chiggers“, particularly Leptotrombidium deliense),^[3] which are found in areas of heavy scrub vegetation. The bite of this mite leaves a characteristic black eschar that is useful to the doctor for making the diagnosis.
