Analysis of extracellular vesicles of Naegleria fowleri. A Through TEM, EVs, which are delimited by a membrane, were observed. Scale bar = 250 nm. B EV size and concentration were determined using NanoSight NS300 equipment. A graphical representation of the size and concentration of extracellular vesicles released by trophozoites after 24 h of incubation is shown
