Syncytium induction in various cells upon infection with CYN07-hV and CYN07-dV. Vero.DogSLAMtag, Vero/macSLAM, Vero/hSLAM, Vero/dNectin4, Vero/macNectin4, Vero/hNectin4, and Vero cells were infected with CYN07-hV and CYN07-dV at an MOI of 0.01, cultured, and observed under a phase-contrast microscope. Syncytia induced in Vero.DogSLAMtag, Vero/macSLAM, and Vero/hSLAM cells at 24 h p.i., in Vero/dNectin4, Vero/macNectin4, Vero/hNectin4 cells at 36 h p.i., and in Vero cells at 36 h p.i. are shown.
