The shapeshifting Helicobacter pylori: From a corkscrew to a ball
Molecular Microbiology, Volume 121, Issue 2, Page 260-274, February 2024.Helicobacter pylori transforms from helical rods to spherical coccoids when faced with various stresses, including starvation and temperature fluctuations. While it remains controversial whether the latter form is dormant or degenerative, a great deal of overlooked evidence points toward the existence of both.
