Effect of S. aureus culture supernatant and oxygen upon P. aeruginosa motility. Swimming and swarming motilities of P. aeruginosa isolates were assessed following an overnight incubation on swimming and swarming agar plates. To test the effects of S. aureus culture supernatant upon these two forms of motility, a 1:100 dilution of the culture supernatant was added to plates before the agar set. Data are presented as mean ± S.E.M from three independent experiments each performed in duplicate. Statistical differences were determined using one-way ANOVA with Tukey’s post-hoc. **P < 0.01 ***P < 0.001.
