Helicobacter pylori, the most common chronic bacterial infection, has shown in two significant structure; bacilli and coccoid form. The coccid form has been detected as a viable but not culturable form which forms in unfavorable situation to survive. This feature leads some problems especially during several sub-culturing the examining H. pylori serotypes. We were targeting this problem, based on finding a suitable environment for conversion the coccoid form to viable and culturable bacilli form.
