Down‐Regulation of gp96 by Orientia tsutsugamushi [PDF]

Microbiology and Immunology, 2004
Abstractgp96 plays a central role in innate as well as acquired immunity, maturation and chemotaxis of dendritic cells, Ab production, and cross‐priming, and is a peptide acceptor in endoplasmic reticulum and an accessory to peptide loading of MHC class I molecules.

Intrinsic fluoroquinolone resistance in Orientia tsutsugamushi

International Journal of Antimicrobial Agents, 2010
Scrub typhus is a public health concern for a population of over a billion humans, with an estimated incidence of one million cases/year in endemic areas. Although doxycycline remains the standard therapy, fluoroquinolones have been used successfully in a few patients.

Serosurveillance of Orientia tsutsugamushi and Rickettsia typhi in Bangladesh [PDF]

The American Society of Tropical Medicine and Hygiene, 2014
Scrub and murine typhus infections are under-diagnosed causes of febrile illness across the tropics, and it is not known how common they are in Bangladesh. We conducted a prospective seroepidemiologic survey across six major teaching hospitals in Bangladesh by using an IgM enzyme-linked immunosorbent assay.

Orientia tsutsugamushi in Chiggers and Small Mammals in Laos

Vector-Borne and Zoonotic Diseases, 2022
Background: Scrub typhus is a leading cause of febrile illness in Laos and accounts for a high burden of disease. There have been no previous studies on the causative agent, Orientia tsutsugamushi, in vector mites ("chiggers") or their small mammal hosts in Laos. Materials and Methods: Small mammals and free-living chiggers were trapped in districts of

Isolation of a New Orientia tsutsugamushi Serotype [PDF]

Microbiology and Immunology, 1997
AbstractOrientia tsutsugamushi, the etiological agent of scrub typhus, is an antigenically diverse organism and many serologically distinct strains have been identified. The 56 kDa protein of O. tsutsugamushi, a major protein in the outer membrane, has been thought to be responsible for this antigenic variability. A strain of O.
