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.

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. Many flagellates that are endobiotic in termites have bacteria attached to the outside. In many cases these are spirochaetes. They move actively and this can produce the propulsive force for the the eukaryote flagellate. Phase contrast.

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. Several different sized-spirochaetes can be seen in this image. From the termite Incisitermes. Very common inhabitants of the gut. Phase contrast.

Spirochaetes have a spiral body and twist through the medium. This cell is from the termite Incisitermes. The bubble at one end is the start of spore formation. Phase contrast.

An electron photomicrograph of two spiral-shaped Treponema pallidum bacteria.Created: 1969

Under a magnification of 201X, this scanning electron micrographic (SEM) image depicted a dorsal view of an unidentified engorged female tick, which had been extracted from the skin of a pet cat while in the process of obtaining its blood meal. Note the presence of some of the cats fur, along with some of its skin tissue in which the ticks gnathosoma were still embedded. See PHIL 9972 and 9973 for additional, less magnified views of this scenario. It is from the basis capituli that the two spread pedipalps, and hidden skin-piercing hypostome and chelicerae emanate. On the dorsal surface of the basis capituli youll see two depressed areas known as the porose areas, through which secretions produced by dermal glands are released.Created: 2006
