They occur in the veins of the bladderand rectum (very rarely entering the general circulation), andcause local inflammation, ulceration and hematuria (Bilhar-ziasis of Africa and Asia). The ova, yellow, translucent and oval(1 mm.), may often be found in the urine or feces. The Cestodes, or Tapeworms Tenia Solium, or Pork Tapeworm.—This parasite is 2 to 4 me-ters long, occasionally much longer, and consists of a small head(1 mm.), spherical and dark brown in color, (scolex), with fourdisc-like suckers and a rostellum armed with a double row ofhooklets (about 30) on its anterior end. The neck is thread-like and one inch long. The body (strobila) is composed of 600. Fig. 72.—Head of T:enia solium.

Each segment(proglottis) is hermaphroditic and has a uterus with seven to fif-teen branches. Groups of segments may be discharged from thebowel at intervals, and each segment has independent ova develop in utero into embryos having six hooklets, andsurrounded with a striated shell (onchosphere). When ingested bythe hog, or rarely other animals, even man, the shells are dissolvedin the stomach and the embryos pass into the tissues where theyform cysts (cysticerci) and develop a scolex. The cysts are visibleto the naked eye, and constitute the measled pork or othermeat. When insufficiently cooked pork is eaten, the scolex or h
