All Spirochete and Other Bacterial Orders

Spirochete and Other Bacterial Orders is a Browse By group of the Nature Atlas that gathers orders of bacteria that belong to none of the proteobacterial or gram-positive groups of this subcategory, such as Spirochaetales, the order of spiral-shaped spirochete bacteria whose members cause syphilis, Lyme disease and relapsing fever. An entry belongs here when its own cited article describes an order of bacteria placed outside the Proteobacteria and the gram-positive phyla. It excludes the archaeal orders, which have a group of their own, and it excludes the orders of other kingdoms. The group lets a reader find the bacterial lineages with unusual body forms that cause some of the best known human infections.
