3 Οκτ 2014 · The disease is transmitted to humans by chiggers of Leptotrombidium spp. and is caused by the bacterium Orientia tsutsugamushi. Noteworthy are the reported cases that suggest other Orientia species as etiological agents of scrub typhus-like disease.
25 Φεβ 2024 · Chiggers are the larvae of the Trombiculidae mite species. Bites from these mite larvae can cause local pruritus and irritation called trombiculiasis or trombiculosis. The reaction is usually mild and self-limited, but the bites can transmit disease or result in bacterial superinfection.
2 Δεκ 2015 · More than 50 species are known to bite humans, and about 20 have medical importance. The larval stages (chiggers) of the genus Leptotrombidium are vectors of Orientia tsutsugamushi, causative agent of scrub typhus.
The larval stage of trombiculid mites (Acari: Trombiculidae), known colloquially as chiggers (see Glossary), are the sole confirmed vectors of intracellular bacterial pathogens of the genus Orientia, the causative agents of scrub typhus.
2 Ιουν 2023 · ‘Chiggers’ (trombiculid mite larvae) are best known as vectors of rickettsial pathogens, Orientia spp., which cause a zoonosis, scrub typhus.
17 Νοε 2022 · Chiggers are the larval stage of Trombiculidae and Leeuwenhoekiidae mites of medical and veterinary importance. Some species in the genus Leptotrombidium and Herpetacarus vector Orientia species, the bacteria that causes scrub typhus disease in humans. Scrub typhus is a life-threatening, febrile disease.
5 Δεκ 2019 · We show that chigger species richness is influenced by mammalian host status, climatic factors and land use; whereas chigger species and geographic region, although not habitat type, significantly affect the β-diversity of chigger microbiomes.
