Document Summary
Taenia solium: humans the only definitive host, distribution worldwide, pork tapeworm- pig as intermediate host, endemic in mexico, sentral/south america, se asia. Infective host is cysticercus in man: we can be both intermediate and definitive host. Saginata can only infect us with cysticerci: this is the most dangerous one for us because we can be both definitive and intermediate host. You can autoinfect yourself from harbored adults: distinguish between solium and saginata- solium has hooks. If the proglottids are fairly fresh, you can tell the difference in the number of uterine branches in proglottids. Tell the differences in that solium has a rostellum on its scolex: man as definitive host: adult gi tract, asymptomatic usually, infected- ate raw or undercooked pork with cysticerci, pig- ingests eggs in human feces contaminated. Cannot be infected by cysticerci: how does man get the eggs, pay attention to this one- by far the worst. Predilection sites include: number one site= subcue tissues.
