Fig. 110.—Egg of Tania saginata, with outer shell and filaments; embryo, with em- bryonal shell, in center. Egg of T. solium (above), show- ing embryo with embryonal shell. Fig. 111.—Mature segment of Taenia saginata (left) and T. solium (right), showing laterally branched uterus. For this reason, with the added one that the larvae may become established in the central nervous system or eye, Tcenia solium consti- tutes a much more serious infestation than does T. saginata. A simple method for determining to which of these two species the infecting tapeworm belongs consists in clearing up a voided segment, pressing it between two clean slides, and observing the form of the gravid uterus as the specimen is held before a strong light. If the median trunt shows numerous delicate lateral branches on each side (20-35) it indicates that the infection is with Tcenia saginata. If these branches are less numerous (7-12) and more robust, it may be concluded that the seg- ment belongs to T. solium (Fig. 111). If treatment has resulted in the expulsion of the entire worm, an exact differentiation can be made by examination of the head under low power magnification. The pork tapeworm will show the cephalic arma- ture which in the beef tapeworm is absent.
