One of the hazards connected with clinical and experimental studies on syphilis is the possible accidental inoculation of the worker with Spirochaeta pallida.cian who treats syphilis or who handles syphilitic animals is liable to be inadvertently stuck, scratched, bitten or in other ways contaminated with spirochetes. The literature contaicon-atainsof such accidents with organisms obtained from both human and animal sources. However, there have been no publishedts of instances in which there was reasonable certainty that spirochetes from an experimental animal had entered the body but in which actual infection did not subsequently occur.
In the case to be reported accidental injection of S. pallida probably did take place without the dissemination of the organisms and frank syphilis ensuing. In addition to this report, a summary of current opinion as to the procedure of choice in the event of such an accident is recorded.
