Among these antigens, OMP-H (CBU_0612) was described as an immunodominant marker for acute and persistent forms of Q fever [35,41], Com-1 (CBU_1910) is considered a reliable Q fever serodiagnosis marker [42,43], and OMP-P1 (CBU_0311) is a porin—highly expressed only in the replicative form of the bacterium in the cell hosts [44,45,46]. Here, VDAC1 is linked to Q fever.
