Scrub typhus is a vectorborne zoonosis caused by
Orientia spp.
(1) The disease is caused by
Orientia tsutsugamushi, an obligate intracellular Gram-negative bacterium, and is transmitted by infected chigger larva.
[4] There are currently three groups of diseases commonly identified as rickettsioses: (i) spotted fever group (SFG) and typhus group (TG) rickettsial infections; (ii) scrub typhus, associated with
Orientia tsutsugamushi (formerly Rickettsia tsutsugamushi); and (iii) human ehrlichioses and anaplasmosis caused by pathogens in the family Anaplasmataceae.
Scrub typhus caused by gram negative coccobacilli bacteria
Orientia tsutsugamushi.
Scrub typhus is an acute febrile illness caused by the organism
Orientia tsutsugamushi an obligate intracellular gram-negative coccobacillus.
(5) It is caused by the infection of
Orientia bacteria which is transmitted to humans through the bite of infected trombiculid larval mites, commonly referred to as chiggers, which serve as vectors and main reservoirs of this pathogenic bacterium.
Dort ana gruba ayrilirlar: Rickettsia (kendi icinde benekli ates ve tifus grubu olarak ikiye ayrilir),
Orientia, Ehrlichia ve Anaplasma.
The bacteria responsible for scrub typhus is
Orientia tsutsugamushi, which is no longer included in the genus Rickettsia, but Dr.
Two rickettsial genera that were detected (Candidatus Megaira and
Orientia) have endosymbiotic (Megaira) and pathogenic (
Orientia) habits.
According to the company, the DPP Fever Panel Assay will include a quality control and nine tests aimed at parasitic, viral and bacterial pathogens commonly responsible for fever symptoms in the Asia Pacific region, including malaria (four Plasmodium species, using pLDH and HRP2), dengue virus, Zika virus, chikungunya virus, leptospirosis, Rickettsia typhi, Burkholderia pseudomallei, and
Orientia tsutsugamushi.
Orientia tsutsugamushi, the etiologic agent of scrub typhus, is also a common cause of acute febrile illness of unclear origin in Asia [1].
AC has also been associated with Salmonella typhi, Bordatella pertussis, Borrelia burgdorferi, Mycoplasma, Coxiella burnetii, group A Streptococcus, and
Orientia tsutsugamushi.
