Analysis of fHBP expression of a B139 meningococcus serogroup C variant by flow cytometry. A representative B139 isolate (A) and the B178 meningococcus sergroup B isolate (B) were analyzed by flow cytometry for surface expression of fHBP using rabbit rfHBP-B01 immune sera and rabbit pre-immune sera as a negative control. The percentage of cells for each of nine isolates harboring B139 that express fHBP by rabbit rfHBP-B01 immune sera range from 3 to 21%. 100% of the B178 bacteria express fHBP by the rabbit immune sera.
