Figure 4. Motility of E. amylovora in soft agar plates at 28 °C, 14 °C and 4 °C after 2 days of incubation.
Vertical lines mark the SD. Swimming motility differences at the three temperatures assayed were very significant (p < 0.001), regardless of the tested strain. These data are from a representative experiment of two, performed in triplicate and with similar results.
