S. Pullorum causes a dysentery-like disease in human beings. It seemed desirable to know its survival time under the conditions indicated above. No recovery could be made from the skin of the back of the hand of a young woman 10 minutes after application (summer). It was recoverable after 45 but not after 60 minutes in the winter. It was recovered from eggs stored 8 months at 25° C and 5 months at 4° C. The usual methods of cooking did not destroy all pullorum bacilli in eggs. Scrambling and four-minute boiling were most effective.
