Morphology of various strains of the trypanosome causing disease in man in Nyasaland: The human strain (Continued).--VI to X

Abstract

In a former paper five strains of this species of trypanosome, obtained from man, were described. In this it is intended to describe another set of five. A small quantity of blood was taken from the sick native, brought up to the laboratory, and inoculated into a monkey or white rat. Strains VII, VIII, and X were directly inoculated into the rat from which the drawing and measurements were made; in strains VI and IX a single monkey intervened. These five stains have therefore been obtained under fairly similar circumstances, and should prove useful for purpose of comparison. This is put in tabular form in table. I, and the histroy of the previous five strains in also given, as this was omitted in the former paper. It is possible that the type of a strain may be changed by passage through different animals before it reaches the rat.
