Fig 2.
Mean spectra were calculated from ∼100 background-corrected single-cell spectra of each investigated strain isolated from agar plates (B. abortus [line a], B. canis [line b], B. ceti [line c], B. melitensis [line d], B. microti [line e], B. pinnipedialis [line f], and B. suis [line g]) and are shown to highlight the close similarity of the spectra. The spectra are vertically shifted for clarity.
