エル・トール・ビブリオ鞭毛の構造

In this experiment it was possible to observe structure of the flagella of El Tor vibrio. Namely, in the observation of the flagella of El Tor vibrio being cultured on alkaline nutrient agar there can be observed a sheath surrounding the core, but morphologically it is quite unstable, revealing swollen sheathed parts due to autolysis and nonsheathed parts exposing the core. It has also be clarified that two kinds of the flagella, big and slender, sometimes observable are the big ones with intact sheath and the smaller ones that have lost their sheath and the core being exposed. The core in sometime is found enlarged in places showing bumps in several portions but it has been demonstrated to be morphologically very stable.
