title: Growth medium containing cyclodextrin and low concentration of horse serum for cultivation of Helicobacter pylori.
abstract: The growth of Helicobacter pylori, a Gram-negative microaerophilic bacterium, is often difficult and requires complex media with the supplementation of 5% to 10% blood or blood derivatives. We have found that Brucella broth supplemented with 1% heated horse serum and 0.1% beta-cyclodextrin supports the good growth of H. pylori. The degree of growth and production of urease and vacuolating cytotoxin in this medium were equal to those in the medium supplemented with 5% horse serum. This medium was found to be suitable for both the routine laboratory culture and primary isolation of H. pylori from biopsy samples.
