Populations of <i>X</i>. <i>oryzae</i> pvs. <i>oryzae</i> and <i>oryzicola</i> decline or remain static when co-cultured with amoeba trophozoites.

Trophozoites were cultured with X. oryzae cells and bacterial numbers in the co-culture medium were assessed at 0, 4 and 24 h. Data from at least four biological replicates were log transformed before calculating the means and standard error bars. * denotes p < 0.05 and ** denotes a p < 0.01 compared to initial CFU/mL values at 0 h. Statistical significance tested using a two-way ANOVA (Tukey test) on the log-transformed data.
