Résumé
Bacteria respond to host immunity for their proliferation and survival by cell-cell communications such as biofilm formation, bioluminescence, and secreting virulence factors. In the biofilm form, bacteria are more resistant to various antimicrobial treatments and withstand the host's immune system. The approaches of deciphering biofilm formation for treating bacterial infections are therefore highly desirable. Recently, we have reported that the ethanolic extract of the red seaweed Gracilaria fisheri (G. fisheri) enhanced immune activities and inhibited growth of the luminescent bacteria Vibrio harveyi in shrimp. We undertook the present research study in order to evaluate and compare the effectiveness of the ethanolic extract from G. fisheri and furanone, a known biofilm inhibitor, in inhibiting the formation of clinically important Vibrio biofilms. The results showed that sub-lethal concentrations of both the ethanolic extracts (5, 10 and 100 μg ml
