Antigenic Relationships among Human Pathogenic Orientia tsutsugamushi Isolates from Thailand [PDF]
, 2016 Scrub typhus is a common cause of undiagnosed febrile illness in certain tropical regions, but can be easily treated with antibiotics. The causative agent, Orientia tsutsugamushi, is antigenically variable which complicates diagnosis and efforts towards ...

Analysis of Orientia tsutsugamushi promoter activity [PDF]
Pathogens and Disease, 2021 ABSTRACT Orientia tsutsugamushi is an obligate intracellular bacterium that causes scrub typhus, a potentially fatal rickettsiosis, and for which no genetic tools exist. Critical to addressing this technical gap is to identify promoters for driving expression of antibiotic resistance and fluorescence reporter genes in O.

Estimating scrub typhus and murine typhus incidence among adolescents and adults in Yangon, Myanmar. [PDF]
Trop Med Int HealthAbstract Objectives Rickettsioses are frequent causes of treatable febrile illness in Southeast Asia, including Myanmar. Accurate estimates of the incidence of rickettsioses are needed to inform investments in disease prevention and control. We sought to estimate the incidence of rickettsioses among adults and adolescents by combining sentinel hospital

Shotgun proteomics of Orientia tsutsugamushi [PDF]
Clinical Microbiology and Infection, 2009 Orientia tsutsugamushi is one of the obligate intracellular bacteria, and causes Tsutsugamushi disease (scrub typhus). The whole genome sequence of Boryong strain revealed some characteristics of this bacterium, such as a type IV secretion system, many histidine kinases, SpoT, Tra, and ankyrin repeatand tetratricopeptide repeat (TPR)-containing ...

Hematogenously disseminated Orientia tsutsugamushi-infected murine model of scrub typhus [corrected]. [PDF]
PLoS Neglected Tropical Diseases, 2014 Orientia tsutsugamushi, the etiologic agent of scrub typhus, is a mite-borne rickettsia transmitted by the parasitic larval stage of trombiculid mites. Approximately one-third of the world's population is at risk of infection with Orientia tsutsugamushi,

Silent Threat: Multi-Organ Failure in Neonatal Scrub Typhus Without Traditional Markers. [PDF]
Clin Case RepABSTRACT Scrub typhus, an acute zoonotic disease from Orientia tsutsugamushi, is uncommon in newborns and presents atypical symptoms. Untimely diagnosis and treatment can lead to a prolonged and potentially fatal course. Early diagnosis and treatment are essential for better patient outcomes.
