Summary

The tegument ofSchistosoma mansoni was studied with the electrone microscope. The results were compared with previously described data and it was found that:

  1. 1.

    The tegument and the underlying “fibrous layer” are thicker on the body wall than on the tail.

  2. 2.

    The so-called “spherical dense bodies” I and II are predominant in the tegument of the cercarial body.

  3. 3.

    The material of the “fibrous layer” and SbII probably take part in forming the “Cercarienhülle”.

  4. 4.

    In addition to the three types of “sinnespapillae” which have been described previously, there seems to be another type (IV. type).

Zusammenfassung

Das Tegument der Cercarien vonSchistosoma mansoni wurde mit Hilfe des Elektronenmikroskops untersucht, die Befunde mit den bisher beschriebenen Daten verglichen und folgendes festgestellt:

  1. 1.

    Das Tegument und die darunter liegende „fibröse Schicht” sind in der Körperregion kräftiger ausgebildet als in der Schwanzregion.

  2. 2.

    Die als „spherical dense bodies” I und II bezeichneten Körperchen treten vorwiegend im Tegument des Körpers auf.

  3. 3.

    Wahrscheinlich sind die mit „fibrösem Material” angefüllte F-Schicht und die SbII-Körper an der Cercarien-Hüllenbildung beteiligt.

  4. 4.

    Außer den bisher beschriebenen drei Typen von Sinnespapillen scheint noch ein vierter Typ vorhanden zu sein.
