Figure 3. Transmission electron microscopy of uninfected and infected cell cultures from the second infection trial. A) Uninfected cells showing normal internal membrane organelles. B) Suspect 29-nm particles in cells, viruses from cell culture lysate from the first infection trial (P1). C) Stool sample flag2 (P0) and D) stool sample 149 (P0) showing numerous 29-nm particles and internal rearrangement of membrane-bound organelles.
