Orientia tsutsugamushi is the causal agent of scrub typhus, a public health problem in the Asia-Pacific region and a life-threatening disease. O. tsutsugamushi is an obligate intracellular bacterium that mainly infects endothelial cells. We demonstrated here that O. tsutsugamushi also replicated in monocytes isolated from healthy donors. In addition, O. tsutsugamushi altered the expression of m...

Scrub typhus is an acute, febrile illness, caused by the bacterium Orientia tsutsugamushi, that affects millions annually in the endemic Asia-Pacific region. In untreated cases, the case-fatality rates range from 6% to 35%. In Bhutan, there was a probable outbreak in Gedu in 2009, which resulted in heightened awareness of the disease. Nevertheless, information on scrub typhus in Bhutan is limit...

Orientia tsutsugamushi, the cause of scrub typhus, is a major pathogen in the Asia-Pacific region. The severity of infection ranges from mild features to multiorgan failure and death. The aim of this prospective study was to define the O. tsutsugamushi loads in the blood samples of patients with scrub typhus on the day of hospital admission and to determine whether this was associated with dise...

BACKGROUND Scrub typhus is a potentially fatal infectious disease caused by Orientia tsutsugamushi. There is little attention given to hepatic impairment in the adults with scrub typhus. This study investigated the incidence and the prognostic implications of hepatic impairment in patients with scrub typhus. METHODS We retrospectively reviewed a total of 143 adult patients with scrub typhus w...

Aim of the Study Scrub typhus has been globally recognized as an emerging infectious disease contributing significantly to pyrexia of unknown origin (PUO) and a potential cause of multiorgan dysfunction syndrome (MODS). We studied the incidence of scrub typhus as a cause of pediatric intensive care unit (PICU) admission and MODS in our hospital and its clinical and laboratory characteristics to...

BACKGROUND Owing to frequent outbreaks witnessed in different parts of the country in the recent past, scrub typhus is being described as a re-emerging infectious disease in India. Differentiating scrub typhus from other endemic diseases like malaria, leptospirosis, dengue fever, typhoid, etc. is difficult due to overlapping clinical features and a lower positivity for eschars in Asian populati...
