Description:

Spirochaetes are motile bacteria. They have very fine flagella attached to the cell surface, and the rotating action of these propel spirochaetes through the medium. Spirochaetes have a spiral body and twist through the medium. These are from the termite Incisitermes. They have got trapped in a bend of a length of a trachea from their host flagellate. The spirochaetes move by turning, and in this case all of the spirochaetes were imaged while moving synchronously. Small Tricercomitus cells are attached to the top of the tracheae. Phase contrast.
