Scrub typhus is a vectorborne zoonosis caused by Orientia
(1) The disease is caused by Orientia
tsutsugamushi, an obligate intracellular Gram-negative bacterium, and is transmitted by infected chigger larva.
 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
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.

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
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, the etiologic agent of scrub typhus, is also a common cause of acute febrile illness of unclear origin in Asia .
AC has also been associated with Salmonella typhi, Bordatella pertussis, Borrelia burgdorferi, Mycoplasma, Coxiella burnetii, group A Streptococcus, and Orientia
