| Abstract | This study was performed to investigate the distribution of N-acyl homoserine lactone (AHL)-producing bacteria in the intestinal tract of ayu Plecoglossus altivelis altivelis for the better understanding of the ecology of opportunistic pathogen in aquaculture environments. The density of AHL-producers was 1.1×10 CFU/ml in the rearing water and 2.8×10-2.8×10 CFU/g in the intestinal tracts while no AHL-producer was detected in artificial feed. The obligate anaerobes isolated from the intestinal tract and rearing water could not produce AHL. A total of 30 AHL-producers were identified as Aeromonas veronii (25 isolates), A. popoffii (3), A. media (1) and Chromobacterium aquaticum (1). These results suggest that involvement of the AHL-producing bacteria should be considered for the further understanding of opportunistic infection in freshwater fish including ayu. |
