Abstract
The morphology of oral spirochetes in animals were studied by the author fluorescentmicroscopically, and the follawing results were obtained.
1. Fluoromicroscopic staining method was prayed best in the observation of oral spirachetes than giemsa's stain.
2. Macro-Borrelia type spircchetes had extra large spiral and Micro-Borrelia type spircchetes had comparatively large spiral, however, the number of spirals were scarce and the length and width of spirochetes were intermediate.
3. Tremponema-type spirochetes were thin, and had short, small and smooth spiral and the number of spiral were numerous.
4. Leptospira type spirochetes were thin, longand had smooth spiral. The number of spirals were numerous.
5. Specific type spirochetes were detected only in canine oral cavity, and were especially thick, short and each spiral was smooth and the number of spirals were scarce.
6. Micro-Borrelia type spirochetes had spirals similar to Borrelia-type spirochetes in the human mouth, however, the number of spiral were scarce and the spirochetes were slightly short.
7. Treponema-type spirochetes were thin, short and intermediate type of spirochetes between human oral and human extra-genital. And these three type were very similar.
8. Leptospira-type spirochetes were different to Leptospira icterohaemorrhagiae and were intermedeiat type of human oral and human extra-genital.
9. Specific type spirochetes (Spirillum type?) were characteristic to canine, and were thicker and longer than human oral spirillum type spirochetes.
10. The morphology and movement of canine oral spirochetes were influenced by various drugs including antibiotics and arsenic compounds.
