Values are means of two replicates and standard errors of means.

Within each variable, values with the same superscript letter are not significantly different according to Duncan’s multiple range test (P > 0.05).

NC−: unchallenged negative control; PC−: unchallenged positive control; Pro−: unchallenged probiotics control; Pro+: challenged probiotic control; PC: challenged positive control; NC+: challenged negative control.
