Probiotic bacteria ingestion modulates male behavior in zebrafish. (A) Schematic representation of the novel tank test (NTT). (B) Individual summaries of the track for each animal in the experiment at 0 and 21 days. (C) Organized summaries from higher to lower scores in the lower subarea. (D) Comparison of the scores registered in the upper zone before and after treatment. (E) Comparison of the number of crossings between the two subareas of the arena at 0 and 21 days. (F) Correlation between “number of crossings” and “total motility” variables integrating data from the three experimental groups after probiotic treatment. Asterisk shows statistically significant differences * (p < 0.0500).
