Figure 2. Localization of YbgF and PrsA in R. heilongjiangensis by immunofluorescence assay.

Figure 2

Slides coated with R. heilongjiangensis cells were incubated with sera from mice immunized with R. heilongjiangensis whole cell antigens plus adjuvant (A), recombinant YbgF plus adjuvant (B), recombinant PrsA plus adjuvant (C), or adjuvant alone (D). After staining with Dylight 488-conjugated goat anti-mouse IgG, the rickettsial cells on the slide were observed under a fluorescence microscope (Olympus BX60).
