title: Adaptation of a microimmunofluorescence test to the study of human Rickettsia tsutsugamuskh antibody.
abstract: A microimmunofluorescence (micro-IFA) test has been adapted to the study of naturally occurring antibody to Rickettsia tsutsugamushi in humans. The micro-IFA test was comparable to the present immlnofluorescent assay in sensitivity and reproducibility, but offered distinct advantages in the quantity of reagents necessary. Also the micro-IFA could be used to simultaneously titer a serum to as many as nine strains of the organism resulting in a great saving of time.
