Abstract
Summary
Human poliomyelitis virus, as naturally present in stools of poliomyelitic patients has been fed to blow flies, Phormia regina. After this feeding, virus was found in the flies for 2 weeks, and in their excreta for 3 weeks.
Results of this type were not encountered when murine-adapted strains of poliomyelitis virus and Theiler's TO strain of spontaneous encephalomyelitis of mice were used. These strains behaved like biologically inert material, such as carmine, in Phormia regina, Phaenicia sericata and Sarcophaga bullata; following their ingestion they were found in gradually decreasing quantities for a period of 5 days.
