Immunofluorescence of FHV-1 and FCV from the coinfected samples. A-D show different hours post infection (hpi). A were taken at 6 hpi. B were taken at 12 hpi. C were taken at 18 hpi, and D were taken at 24 hpi. DAPI showed a blue fluorescence signal and was used to detect the cell nucleus. FHV-1 showed a green fluorescence signal, and FCV showed a red fluorescence signal
