A, B, C, D: Gravid proglottids of Taenia saginata (Figures A and B) and Taenia solium (Figures C and D).  Injection of India ink in the uterus allows visualization of the primary lateral branches.  Their number allows differentiation between the two species: T. saginata has 15 to 20 branches on each side (Figure A and B), while Taenia solium has 7 to 13 (Figures C and D).  Note the genital pores in mid-lateral position.
