Key result
Six antigens were identified in three prototype strains of Rickettsia tsutsugamushi, with strains Karp and Kato each having two distinct antigens that did not react with heterologous antisera.

Strain-specific antigens should not yet guide scrub typhus care; leaves open vaccine and diagnostic development in humans.
The study identified specific antigens in Rickettsia tsutsugamushi strains that retain immunogenicity after electrophoresis and show strain-specific reactivity.
Eisemann et al. (1981) studied Scrub typhus (Rickettsia tsutsugamushi). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and enzyme-linked immunosorbent assay was evaluated on Antigen identification and reactivity. Six antigens were identified in three prototype strains of Rickettsia tsutsugamushi, with strains Karp and Kato each having two distinct antigens that did not react with heterologous antisera.
