Orientia tsutsugamushi: A life between escapes [PDF]

MicrobiologyOpen, 2023
Intracellular bacteria have evolved different strategies to invade, replicate and persist in, and eventually exit from their hosts. The life cycle of the mite-borne, obligate intracellular pathogen Orientia tsutsugamushi (Ot), the causative agent of human scrub typhus, differs in many aspects from that of other members of the Rickettsiales order ...

A Rare and Severe Multisystem Cascade of AKI, ARDS, and Septic Shock Leading to Acalculous Cholecystitis in a Young Scrub Typhus Patient: A Case Report From Nepal. [PDF]

Clin Case Rep
ABSTRACT Scrub typhus, caused by Orientia tsutsugamushi, is an acute febrile illness prevalent in Nepal with a wide spectrum of clinical presentations. Severe forms can lead to multiorgan dysfunction, including acute kidney injury (AKI), acute respiratory distress syndrome (ARDS), septic shock, and rarely, acalculous cholecystitis.

Vaccine Design and Vaccination Strategies against Rickettsiae

Vaccines, 2021
Rickettsioses are febrile, potentially lethal infectious diseases that are a serious health threat, especially in poor income countries. The causative agents are small obligate intracellular bacteria, rickettsiae.

Development of a New Genus-Specific Quantitative Real-Time PCR Assay for the Diagnosis of Scrub Typhus in South America

Frontiers in Medicine, 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”, have been discovered in the ...

Molecular Epidemiology and Genetic Diversity of Orientia tsutsugamushi From Patients and Small Mammals in Xiangyun County, Yunnan Province, China. [PDF]

Vet Med Sci
Scrub typhus is caused by Orientia tsutsugamushi (OT). In this study, the detection rates of OT in patients and small mammals were 28.13% (18/64) and 13.98% (13/93), respectively. Nine full‐length 56‐kDa TSA genes were identified, comprising four distinct genotypes: Karp‐like (n = 3), Kato‐like (n = 3), Gilliam (n = 2), and TA763 (n = 1). Recombination

Molecular Description of a Novel Orientia Species Causing Scrub Typhus in Chile

Emerging Infectious Diseases, 2020
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 discovered in southern Chile.
