ELISA and micro-IFA using only the expected serotype of O. tsutsugamushi strains in patient sera. The expected serotype of the infecting strain was determined as the most reactive serotype showing the highest ELISA value. Paired sera from 19 patients were used. Each square and diamond shows the reactivity of the first and the second serum sample against the expected serotype of the infecting strain, respectively. The cut-off values of the mean + 3 SD and 1:80 were adopted for ELISA and micro-IFA, respectively. Non-linear regression analysis was performed to determine correlations (R2) between the ELISA results and micro-IFA titers
