Serological specificity of the major seroreactive surface-exposed proteins of R. heilongjiangensis analyzed by ELISA using serum samples from mice infected with different rickettsial agents.

The sera from mice infected with R. heilongjiangensis (R. hei), R. sibirica (R. sib), R. rickettsii (R. ric), R. prowazekii (R. pro), R. typhi (R. typ), O. tsutsugamushi (O. tsu) or C. burnetii (C. bur), or normal mouse sera (Normal) were used to test the specificity of the major seroreactive surface-exposed proteins of R. heilongjiangensis.
