Figure 5. Release of infectious virus progeny to cell culture supernatants. Primary porcine corneal epithelial cells, PPCE (A), primary human corneal epithelial cells, PHCE (B), primary porcine corneal keratocytes, PPCK (C), and primary human corneal keratocytes, PHCK (D) after infection with human adenovirus-D37 and -D22, respectively. Calculated p values relate to human adenovirus-D37 (HAdV-D37) and HAdV-D22 virus titers at 168 h PI (unpaired, two-tailed Student t test).
