Serological sensitivity and specificity values of the major seroreactive surface-exposed proteins of R. heilongjiangensis from microarray and ELISA tests.

R. hei, R. heilongjiangensis; SFG, Spotted fever group; Se, sensitivity; Sp, specificity.*proteins with >70% sensitivity and >85% specificity were selected as potential markers for R. heilongjiangensis or SFG rickettsia infections.#concordance between ELISA and microarray assays used in the present study.
