Clinical and Laboratory Variation of Virulence in Scrub Typhus

Summary 1. Clinical data are presented on one small and 2 large outbreaks of scrub typhus which occurred in 3 different geographical locations in the SWPA and which showed variation in the severity of illness. 2. Representative strains of the causative agent, Rickettsia orientalis were isolated in white mice from cases in the 3 areas and produced typical reactions in white mice, guinea pigs and rabbits. 3. Strains isolated from cases in an outbreak with an extremely low mortality rate were less virulent for laboratory animals than strains isolated from cases in two other outbreaks with higher mortality rates.

A Scrub Typhus (Tsutsugamushi) Outbreak in Dutch New Guinea

Little information concerning scrub typhus (tsutsugamushi fever) as it occurs in Dutch New Guinea has ever been recorded. Gunther (1940) stated that although numerous cases of scrub typhus had been noted in territories under Australian mandate, no cases had ever been reported from Dutch New Guinea. It is known, Kohls et al (1945), that in New Guinea the disease is caused by Rickettsia orientalis, that these organisms are found in native wild rat populations, that certain species of mites belonging to the subfamily TROMBICULINAE are vectors, and that these mites appear to prefer grassy moist areas in which to complete their development. This report is a study of an epidemic of scrub typhus which occurred among American troops during August and September of 1944 at an advanced base in Dutch New Guinea.
