  • Röhl in a more recent publication (Zeitschrift f. Immunitätsforschung, Vol. II, p. 496, 1909), points out that Levaditi does not furnish any conclusive proof for his conception of the formation of trypanatoxyl in the organism, and asserts that the trypanocidal effect of Atoxyl in vivo is only due to the formation of p-amino-phenyl arsenoxide.

  • Strains of trypanosomes resistant to tartar emetic have also been obtained by Mesnil and Brimont, by Plimmer and Bateman; and a strain of T. brucei resistant against p-amino-phenyl-stibinic acid has been obtained by us. This resistance, however, was not transmissible on subinoculation. Mesnil and Brimont succeeded in obtaining a permanent antimony resistant strain by treating an Atoxyl-resistant strain with antimony. At first the parasites were influenced by tartar emetic, but after the fifth injection they became resistant, a resistance which persisted for seventy-six passages.
  • A similar relative resistance was observed by us when treating guinea-pigs infected with T. gambiense with Orsudan. After six to seven injections the drug had lost its influence on the parasites.
  • Uhlenhuth, Hübner and Woithe, working with T. equiferdum, were not able to confirm entirely Ehrlich's observations. They were only able to produce a resistince in one animal after a certain number of relapses. On subinoculation, Atoxyl influenced the parasites in a normal way. Therefore, they regard it as a relative resistance, distinguishing it from an absolute resistance in Ehrlich's sense of the term.

  • Changes of virulence have been noted on a few occasions in the case of T. gambiense. On one occasion T. gambiense was recovered from the blood of a monkey at the time of a relapse, after a prolonged negative interval. The number of parasites in the blood of the monkey increased very rapidly within two days and killed the animal. On subinoculation into rats it was noticed that these animals succumbed to the infection usually within 3 to 4 days. After a passage through guinea-pigs the heightened virulence of the strain was lost, and it killed rats again in the normal period, namely 40–120 days.
