Fig. 3. RSV-EAVs isolation and infectivity assay.
Micrographs (40x) of a Released extracellular amoebal-vesicles containing RSV and b Attached amoebae trophozoites. c Replication kinetics of the control RSV alone (black bar) and RSV-EAVs (white bar) analysed by TCID50 on Hela cells. Data are the mean ± SEM, n = 3 performed in triplicate. d Micrographs (20x) of cytopathic effect (CPE) induced by RSV-EAVs infection in Hela cells at 5 days post-infection.
