Fig. 1From: Excretory-secretory products from the brown stomach worm, Teladorsagia circumcincta, exert antimicrobial activity inĀ in vitro growth assaysVisual characterisation of Teladorsagia circumcincta extracellular vesicles (EVs) using nanoparticle tracking analysis (NTA) and transmission electron microscopy (TEM). a Size distribution of size-exclusion chromatography (SEC)-purified EVs from excretory-secretory products (ESPs) of adult T. circumcincta, according to NTA performed on a NS300 instrument. b Representative image of SEC-purified EVs from adult T. circumcincta captured by the NanoSight NS300 instrument (error bars indicate standard error of the mean). c TEM images of EVs from whole ESPs of adult T. circumcincta and dĀ SEC-purified EVs. Scale bars are provided at the bottom left corner of c and dBack to article page
