Laser scanning confocal microscopy of Vero/hSLAM cells coinfected by MeV and HSV-1 from different passages. Vero/hSLAM cells were infected with virus isolated from the clinical throat swab from SH13390 at the third, sixth, and tenth passage; these cells and a cell control (3^rd, 6^th, 10^th, CC) as indicated on the left were subjected to immunostaining using antibodies against MeV M (green) and HSV-1 ICP0 (red) protein. Images were captured at 40× magnification using a Leica TCS SP8 confocal microscope (Leica Microsystems; Wetzlar, Germany). The cell nuclei were stained with DAPI.
