title: [Persistence of pleomorphism and the presence of multinuclear forms in experimental infection with T.b. brucei].
abstract: Thirty white male mice SWISS ICO NMRI (IOPS) were inoculated intraperitoneally with blood-forms of T.b. brucei of a strain belonging to the Laboratory of Parasitology of the Medicine Faculty of the U.A.M. (Autonom University of Madrid). This strain was preserved during 8 years through inoculation from mice to mice. This strain was received from the Pasteur Institute from Paris. Once infected the mice were submitted to a controle through GIEMSA coloured smears. The various blood-forms registered during the experimental infection were carefully measured and also their proportional presence during the observation. We could appreciate an augment of the Slender forms following the progress of the infection and the apparition of the Stumpy at 48 hours after the inoculation as well as the multinucleate forms. Stumpy forms in division were also observed.
