Later studies of the organism convinced C. FrankelJ that it was a separate species. For it Novy later sug- gested the name Spirochaeta kochi. In 1906 Norris, Pappenheimer and Flournoy§ found a spirochaeta in the blood of a patient suffering from relapsing fever in New York. This having been extensively studied by Novy, has since been called Spirochseta novyi. With the work of Schaudinn and his associate, Hoffman, || the spirochaeta came to be regarded as protozoan parasites because of the presence of an undulating membrane; the refusal of most of the organisms to grow upon artificial media, the r61e of an intermediate host (ticks, etc.) in transmitting them, and the longitudinal mode of division. Fevers characterized by relapses and by the presence of spirochaeta. Fig. 198.—Spir-ochseta recurrentis from ituman blood (KoUe and Wassermann). in the blood have been found in northern and northeastern Europe (true relapsing fever with Spirochaeta recurrentis), in various parts of equatorial Africa (African relapsing fever with Spirochaeta dut- toni) ; in North Africa (Spirochaeta berbera); in Bombay and in other parts of India (Spirochaeta carter!); in Persia (Spirochaeta persica); and in America (Spirochaeta novyi). The question, therefore, arises whether these similar diseases are slight modifications of the same * "Jour. Infectious Diseases," 1906, m, p. 295. t "Deutsche med.
