HS plays a role in henipavirus infection. (A) Vero cells were either treated with heparinase 3 or left untreated prior to NiV infection. Titration was performed 3 days later in a plaque assay. (B and C) Vero cells were treated with increasing concentrations of sodium chlorate for 48 h and then infected with either NiV (B) or HeV (C); titration was performed 3 days later in a plaque assay. Results are expressed as a percentage of results for nontreated controls from triplicate cultures, ± the SD. *, P < 0.05; **, P < 0.01; ***, P < 0.01 (Mann-Whitney U test).
