Our in vivo challenge test showed that cinnamaldehyde and the thiophenone can protect the larvae from Vibrio harveyi infection when dosed to the culture water at 1 μM and 10 μM,whereas the brominated furanone offered protection at 1 μM but resulted in complete mortality at 10 μM. Although there were significant differences in survival between challenged larvae with and without
addition of quorum sensing-disrupting compounds, there were no differences in growth
