Photo 2. Cysticercus in pork. The larval cysticercoid stage occurs in the pig. Man is infected by ingesting uncooked pork. (x3)

Scolex of T. solium and T. saginata.

Photo 3. Scolex of T. solium and T. saginata. The head of T. solium is armoured with hooks in addition to four suckers. Its gravid segments {see 588) contain a central uterus with less than a dozen lateral branches. The eggs are similar to those of other Taenia species. (x40)

Scolex of T. solium and T. saginata too.

X-ray of cysticercosis of soft tissues.

Photo 5. X-ray of cysticercosis of soft tissues. The cysticercoid stage of T. solium (Cysticercus cellulosae) can also occur in man if eggs are released in the intestine, sometimes following incorrect use of taenicidal drugs. When calcification occurs the cysticerci are seen by X-raying the soft tissues adjoining the thighs and shoulders.

Cysticercosis of brain.

Photo 7. Cysticercosis of brain. When cysticerci lodge in the brain calcification can occur, but usually much later than in the soft tissues, and often after epilepsy has manifested itself.
