title: Growth of Helicobacter pylori in various liquid and plating media.
abstract: The objectives of this research were to compare commonly used liquid and plating media to elucidate whether one medium provided superior growth of Helicobacter pylori in vitro. The liquid media compared were Mueller-Hinton broth, brain heart infusion broth and H. pylori special peptone broth, formulated in this laboratory. No significant differences in growth rates were noted and shaking during the incubation of broths was not essential for good growth. The plating media compared included Columbia agar, Mueller-Hinton agar, modified Glupczynski's Brussels campylobacter charcoal agar, Johnson-Murano agar and H. pylori special peptone agar (HPSPA). None of the non-specific plating media that have been used historically to culture H. pylori exhibited any particular advantage. However, HPSPA provided an obvious advantage in colony size. Helicobacter pylori special peptone agar enhances the cultivation of H. pylori and could improve the recovery of the bacterium from clinical samples in vitro.
