FIG. 5.

Inhibition of infection by sialyllactose. Viruses were incubated with or without 9 mM sialyllactose (sial.) before infection of BHK-21 cells. Culture supernatants of infected cells were collected after one cycle of infection, and virus production was quantified by plaque assay. Infections by sialyllactose-treated (hatched columns) and untreated (black columns) viruses are compared. Virus production by cells infected with untreated viruses was taken as 100%. The histogram shows one experiment representative of three independent experiments.
