The infection of MA104 cells by the porcine RVA strains 13R054 G5P[7] and 12R046 G9P[23] is strongly reduced by β-lactose. (A) The effects of pre-incubation of the virus with β-lactose on the infectivity of the porcine RVAs 13R054 G5P[7] and 12R046 G9P[23] were assessed using an immunofluorescence assay with polyclonal antibodies against the RVA VP6 protein. (B) The infection of MA104 cells with both RVA strains was expressed as percentage of infected cells and compared with the mock-treated, virus-inoculated control. (C) The titration of the supernatant was performed on MA104 cells. All experiments were performed in three independent experiments. Error bars in the panel represent the means ± the SD from triplicate experiments. ^**, P < 0.01. *, P < 0.05. ns, P > 0.05.
