The metabolism of the spirochaete is unknown. It is an illness caused by a spiral bacterium called a spirochaete. It is a member of the Spirochaete family. There is a one-to-one relationship between bracket, spirochaete and basal bacterium. These cause a twisting motion which allows the spirochaete to move about. In syphilis, the gumma is caused by reaction to spirochaete bacteria in the tissue. The latter is also characterised by spirochaete epibiotic symbionts. This motile bacillus is a spirochaete. These suggested that the tick can not transmit this strain of spirochaete (. Borrelia valaisiana is a spirochaete bacterium; strain VS116 is the type strain. He believed that yellow fever was caused by spirochaete bacteria instead of a virus. This motile bacillus is a gram negative, facultative anaerobe and a spirochaete. When reproducing, a spirochaete will undergo asexual transverse binary fission. The responsible spirochaete is readily identifiable on sight in a microscope as a treponema.
