Molecular Description of a Novel Orientia Species Causing Scrub Typhus in Chile
(2020-09)
Scrub typhus is a potentially fatal rickettsiosis caused by Orientia species intracellular bacteria of the genus Orientia. Although considered to be restricted to the Asia Pacific region, scrub typhus has recently been ...
Development of a New Genus-Specific Quantitative Real-Time PCR Assay for the Diagnosis of Scrub Typhus in South America
(2022)
Scrub typhus is a potentially severe rickettsiosis, caused by Orientia tsutsugamushi in the Asia-Pacific region. Recently, however, two distinct pathogens, “Candidatus Orientia chuto” and “Candidatus Orientia chiloensis”, ...
Human seroepidemiology of Rickettsia and Orientia species in Chile – A crosssectional study in five regions
(2020)
In recent years, the spectrum and epidemiology of human rickettsioses has become an emerging topic in Chile.
This survey aimed to assess the seroprevalence of spotted fever group rickettsiae (SFGR), typhus group rickettsiae ...
An Update on Host-Pathogen Interplay and Modulation of Immune Responses during Orientia tsutsugamushi Infection
(2018)
The obligate intracellular bacterium Orientia tsutsugamushi is the causative agent of scrub typhus in humans, a serious mite-borne disease present in a widespread area of endemicity, which affects an estimated 1 million ...
Endemic Scrub Typhus-like Illness, Chile
(Centers for Disease Control an Prevention, 2011)
We report a case of scrub typhus in a 54-year-old man who was bitten by several terrestrial leeches during a trip to Chiloe Island in southern Chile in 2006. A molecular sample, identified as related to Orientia tsutsugamushi ...
Endemic scrub typhus in South America.
(Massachusetts Medical Society, 2016)
Scrub typhus is a life-threatening zoonosis caused by Orientia tsutsugamushi organisms that are transmitted by the larvae of trombiculid mites. Endemic scrub typhus was originally thought to be confined to the so called ...
Scrub typhus: A new cause of acute undifferentiated febrile illness in Latin America?
(2021)
Classical scrub typhus or tsutsugamushi disease, caused by rickettsial bacteria of the species Orientia tsutsugamushi, is a re-emerging vector-borne infectious disease that affects more than one million people annually in ...
Novel Vector of Scrub Typhus in Sub-Antarctic Chile: Evidence From Human Exposure
(2021)
The exposure of a research team to chigger mites in southern Chile allowed the first identification of a trombiculid species as vector and reservoir of scrub typhus outside the tsutsugamushi triangle, providing unique ...
