HCoV-OC43 infection in VERO cells, primary human taste (HBO) cells, and olfactory cells (hOECs). A–C VERO, HBO, and hOECs were infected with HCoV-OC43 at different MOI (1, 10, 25, and 50 MOI); RNA and media were collected. A HCoV-OC43-infected VERO cell culture media were processed for RT-qPCR. B HCoV-OC43-infected HBO cell culture media were processed for RT-qPCR. C HCoV-OC43-infected hOEC culture media were processed for RT-qPCR. D–H Vero cells, HBO cells, and hOECs were infected with HCoV-OC43 at 25 MOI; culture media were collected daily, and cellular RNA was extracted at 7 dpi. D HCoV-OC43-infected VERO cell culture media were processed for RT-qPCR. E OC43-infected HBO cell culture media were processed for RT-qPCR. F OC43-infected hOEC culture media were processed for RT-qPCR. G HCoV-OC43-infected Vero cell, HBO cell, and hOEC cellular RNAs were processed for RT-qPCR and shown as bar graph. H Quantification of number of plaques forming units/mL. Data are shown as mean EM of two independent replicates
