The microarray results suggest that GroEL, PrsA, RplY, SurA, and YbgF may be potential markers of R. heilongjiangensis infection and OmpB-3 may be a potential marker of SFG rickettsia infection since they had over 70% sensitivity and 85% specificity in this serological analysis (Table 5). This evidence concerns the gene GLRX5 and Rickettsiosis.
