Newly isolated strains of Rickettsia tsutsugamushi in Japan identified by using monoclonal antibodies to Karp, Gilliam, and Kato strains

Abstract

Four isolated strains of Rickettsia tsutsugamushi from patients in a new endemic area of Japan were tested for antigenicities by using 12 monoclonal antibodies to Karp, Gilliam, and Kato strains. It was suggested that one isolate was Karp related and that the others were two independent strains.
