ResumoThe growth and development of metacestodes of Taenia crassiceps in mice was studied after experimental oral infection with cysticerci. Soon after infection, the holdfasts of most cysticerci evaginated in the stomach, and usually the bladders detached before the worms reached the small intestine. From the intestine, some worms entered the peritoneal cavity within the first 24 h. Others remained in the gut lumen up to 16 days. Very rarely were the rostellar hooks everted on evaginated holdfasts in the intestine and only slightly more commonly on holdfasts in the peritoneal cavity. Some worms in the small intestine and some in the peritoneal cavity segmented and developed genital primordia, although they did not become sexually mature. A few worms in the peritoneal cavity resumed asexual reproduction by budding, either from bladder tissue that had been pulled into the cavity by the penetrating worms, or from solid (nonbladder) tissue.
