Antibodies against MERS Coronavirus in Dromedary Camels, United Arab Emirates, 2003 and 2013
Figure. . . Immunofluorescence and microarray reactivity patterns for antibodies (SF74, H40, H97, and S11) against Middle East respiratory syndrome coronavirus (MERS-CoV) in serum samples from camels, United Arab Emirates, 2013. A) Serum samples tested against overexpressed MERS-CoV spike protein (MERS-S), overexpressed human CoV-OC43 spike protein (OC43-S), and Vero cells infected with MERS-CoV (MERS-V). Fluorescence intensities were evaluated as follows: –, negative; +, weakly reactive; ++, reactive; +++, strongly reactive. Scale bar indicates 20 μm. B) Relative fluorescence units (RFU) were determined for the same serum samples by microarray using S1 domains of MERS-CoV and human CoV-OC43.
