Cultivation of the Spirochætes Associated with Tropical Ulcer.
Spirochaetes from cases of tropical ulcer have been cultured in a modified Wenyon media and have now been successfully passed through thirty-two subcultures.-A pure culture has not yet been obtained.-Five inocultation experiments are described in which it has been shown that the spirochaetes and fusiform bacilli, in mixed culture, are capable of proliferation and of producing ulcerated lesions in natives.
