Figure 2

Marburg virus antibody responses in bat species in communities bordering Equatorial Guinea Marburg outbreak, Cameroon, 2023. MFI values for Marburg virus antigens nucleoprotein (A), glycoprotein 1 (B), and 40-kDa viral protein (C) are shown for 9 bat species. The red dashed horizontal line represents the seropositivity threshold, derived from log-transformed negative-control MFI values (mean +4 SD; n = 150) and back-transformed to the original MFI scale (nucleoprotein, 191; glycoprotein 1, 88; 40-kDa viral protein, 1,173). MFI, median fluorescence intensity.
