Leptotrombidium

Leptotrombidium

(lep'tō-trom-bid'ē-ŭm),
An important genus of trombiculid mites, formerly considered a subgenus of the genus Trombicula, which includes all of the vectors of scrub typhus (tsutsugamushi disease). Members of Leptotrombidium that serve as vectors of scrub typhus are within the Leptotrombidium deliense group: Leptotrombidium akamushi is the classical vector in Japan; Leptotrombidium deliense is the primary vector, extending from New Guinea, Australia, the Philippines, China, and Southeast Asia to western Pakistan; Leptotrombidium fletcheri is found in Malaysia, New Guinea, and the Philippines. Some eight other species have also been implicated in scrub typhus transmission in more limited areas.

Scrub typhus is an acute febrile infection transmitted by the bite of leptotrombidium, chigger mite larvae.
For instance, in the South Pacific, Oceania, and Asia trombiculid mites of the genus Leptotrombidium are known to be vectors of tsutsugamushi, also known as scrub typhus.
In contrast, Leptotrombidium scutellare mites are major scrub typhus vectors with high density during autumn (scrub typhus season) (12).

The infectious disease is spread by some species of trombiculid mites, particularly Leptotrombidium deliense.
