The Genesis of Coccal Forms of Helicobacter pylori
In prolonged culture the morphology of Helicobacter pylori  alters from “the normal” helical form to a spherical cell via U- and V-shaped forms. This morphological transformation may be the result of less than optimal cultural conditions, a reaction to waste products, or it may be a natural phenomenon. This paper describes the formation of these atypical forms with an explanation of the mechanism of their genesis.
