a
Swimming was determined as migration from the source of inoculation on TG medium containing 0.35% agar at 26°C. Swimming was scored as positive (+), negative (−), or variable (±).
b
Swarming was determined as surface migration on TG medium containing 0.6% agar at 26°C. Swarming was scored as positive (+), negative (−), or variable (±).
