Comparison of early and late infectivity between TGEV PUR46, HAD3 and TGEV Miller. The infectious titers of TGEV PUR46, HAD3 and TGEV Miller were calculated at adsorption times of 5, 20 and 60 min, respectively. Infectivity was expressed in plaque forming units per ml (PFU/ml). Prior to infection, ST cells were incubated with either PBS (1, 4, 5) or PBS containing 50 mU of neuraminidase (2, 3, 6).
