Approaches to vaccines against Orientia tsutsugamushi [PDF]

Frontiers in Cellular and Infection Microbiology, 2013
Scrub typhus is a severe mite-borne infection caused by Orientia tsutsugamushi, an obligately intracellular bacterium closely related to Rickettsia. The disease explains a substantial proportion of acute undifferentiated febrile cases that require hospitalization in rural areas of Asia, the North of Australia, and many islands of the Pacific Ocean ...

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 ...

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.

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.

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.

Scrub Typhus in a New Born [PDF]

Journal of Clinical and Diagnostic Research, 2017
Scrub typhus is an acute febrile mite-born rickettsial infection caused by Orientia tsutsugamushi (formely called Rickettsia tsutsugamushi). This infection is very uncommon in neonates.

<i>Orientia tsutsugamushi</i> in Chiggers and Small Mammals in Laos. [PDF]

Vector Borne Zoonotic Dis, 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

Bacterial microbiome of the chigger mite Leptotrombidium imphalum varies by life stage and infection with the scrub typhus pathogen Orientia tsutsugamushi.

PLoS ONE, 2018
Scrub typhus is a mites-borne rickettsiosis caused by the obligate intracellular Gram-negative bacterium Orientia tsutsugamushi. The disease is potentially life threatening and is prevalent in tropical Asia, islands of the western Pacific Ocean and ...

Male-killing bacteria in insects: mechanisms, incidence and implications [PDF]

, 2000
Bacteria that are vertically transmitted through female hosts and kill male hosts that inherit them were first recorded in insects during the 1950s. Recent studies have shown these "male-killers" to be diverse and have led to a reappraisal of the biology
