Extended Data Fig. 2: Immuno-TEM (Transmission Electron Microscopy).

Additional micrographs of phage øSimón incubated with patient’s serum from before phage therapy (Day 0) or after 21 days of phage therapy, and a gold-labelled anti-human IgG detection antibody (black dots) (left and middle columns, respectively). Assorted controls for the experiment on the right column. Scale bars depicted at the bottom corner of every micrograph. Images are representative of at least 100 observations from two experiments each.
