Clinical deterioration in community acquired infections associated with lymphocyte upsurge in immunocompetent hosts [PDF]

, 2004
Clinical deterioration during the course of community-acquired infections can occur as a result of an exaggerated immune response of the host towards the inciting pathogens, leading to immune-mediated tissue damage.

Classification of Rickettsia tsutsugamushi in a New Genus, Orientia gen. nov., as Orientia tsutsugamushi comb. nov. [PDF]

International Journal of Systematic Bacteriology, 1995
Recent studies of Rickettsia tsutsugamushi have demonstrated clearly the phenotypic and genotypic differences between this microorganism and other species belonging to the genus Rickettsia. Therefore, classification of R. tsutsugamushi in a new genus, Orientia gen. nov., is proposed.

A time-course comparative clinical and immune response evaluation study between the human pathogenic Orientia tsutsugamushi strains: Karp and Gilliam in a rhesus macaque (Macaca mulatta) model [PDF]

, 2022
BACKGROUND: Scrub typhus is a vector-borne febrile illness caused by Orientia tsutsugamushi transmitted by the bite of Trombiculid mites. O. tsutsugamushi has a high genetic diversity and is increasingly recognized to have a wider global distribution ...

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.

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.
