Abstract
Cultures of Helicobacter pylori on chocolate agar slants in bijou bottles and on chocolate agar plates inside BBL Campy Pouches were mailed from Dublin to Galway, Ireland; Bordeaux, France; and Beijing, China. Both systems maintained viability of H. pylori for at least 4 days under mailing conditions. Ninety percent of the isolates on the slants survived for 6 days, but only 30% of the isolates in the pouches survived. When the slants were stored at 4 degrees C after arrival, 50% of the isolates were recoverable 10 days after mailing. Failure of recovery was due to coccoid formation by the organisms. Contamination was not a problem in either system. Chocolate agar slants are considered the more suitable system for transporting H. pylori cultures, especially when transport time longer than 4 days is expected.
