Endotube-brush border complexes dissected from the intestines of Haemonchus contortus and Ancylostoma caninum.

A procedure for the blunt dissection of the syncytial intestine of Haemonchus contortus to separate the endotube-brush border complex is described. A similar complex can be obtained from the partially cellular intestine of Ancylostoma caninum. The structural features of the complexes from the two sources are compared. The main differences are in the retention of terminal bars by the endotube from A. caninum and in the extent and organization of the microfilaments associated with the basal side of the endotubes.
