Attempts were made to detect tetrodotoxin (TTX)-producing bacteria in the Thai horseshoe crab Carcinoscorpius rotundicauda, one of TTX-containing marine invertebrates. Thirteen dom-inant bacteria were isolated from the intestinal contents of live horseshoe crab specimens, and were cultured in a 2 × ORI medium at 20°C for 24h. Bacterial cells of each strain were harvested, ultrasonicated and ultrafiltered, and TTX and anh-TTX fractions were separated from the filtrate by Bio-Gel P-2 column chromatography. HPLC, UV and GC-MS analyses showed that all out of the 13 strains isolated produced anh-TTX, and one strain produced TTX and anh-TTX. The strain which produced both toxins was identified as Vibrio alginolyticus on the basis of biochemical and other characters.

@ni075 少し調べてみるとタイの食中毒の主な原因種であるマルオカブトガニからTTX産生性のビブリオ菌の仲間が分離された例がありました。 https://t.co/pkCLgVTFe7
