Evaluation of different solid media used for cultivation of Helicobacter (Campylobacter) pylori.

The ability of nine blood containing media to support the growth of H. pylori was compared. Eighteen strains of H. pylori isolated from antral biopsies were cultivated in two dilutions, for colony counts on the media to be tested. Columbia base chocolate agar without additives was found to be the best medium for growth of H. pylori. However, all other fresh blood containing media also supported the growth of this organism satisfactorily.
