The uterus consists a central stem with 18 to 33 lateral branches on each side. The gravid prolottids contain about 80 thousands eggs. About 10 proglottids are shed daily in the feces or migrate spontaneously from anus. Proglottids are motile and will migrate a few centimetres over body, clothes, beds, ground etc. shedding eggs by this process. The eggs remain viable for several weeks or months in sewage, rivers and on pasture.
Sewage is important route of dissemination of eggs.
Eggs can pass through sewage treatment plants and be released into rivers or be disseminated by birds feeding on raw sewage. When cattle eats the eggs. The oncosphere hatches and activates under the influence of gastric and intestinal juices then penetrates the intestinal mucosa to reach the general circulation. The embryos will be disseminated throught out the body and develop in skeletal cardiac muscle, fat and organs, especially the muscles of heart and masseters, diaphragm and tongue. Usually cysticercus are spread throughout the musculature.
