Coccoid forms of Helicobacter pylori are the morphologic manifestation of cell death.
Helicobacter pylori can transform from its normal helical bacillary morphology to a coccoid morphology. Since this coccoid form cannot be cultured in vitro, it has been speculated that it is a dormant form potentially involved in the transmission of H. pylori and in a patient's relapse after antibiotic therapy. In this study we determined the effects of aging, temperature, aerobiosis, starvatio...
متن کاملCoccoid forms of Helicobacter pylori.
To the Editor-Eaton et al. [1] recently described experiments with coccoid Helicobacter pylori in gnotobiotic piglets. This interesting study examined the colonization and the reversion from coccoid to bacillary H pylori within 2 weeks of inoculation. Piglets colonized with bacillary H pylori had more severe gastritis 2 weeks after inoculation than did those sacrificed 1 week after inoculation....
متن کاملCoccoid form of Helicobacter pylori as a morphological manifestation of cell adaptation to the environment.
After characterization of preferred conditions for Helicobacter pylori survival in the sessile state, it was observed that the bacterium transforms from spiral to coccoid under mild circumstances, whereas under extreme ones it is unable to undergo shape modification. This strongly supports the view that transformation into the coccoid form is an active, biologically led process, switched on by ...
