Cystic echinococcosis in Sudan and South Sudan: research history of a neglected zoonosis.

Cystic echinococcosis is a zoonotic disease affecting mainly various species of livestock and humans. This study aims at highlighting the course of research on cystic echinococcosis in different animals and humans in Sudan (including the recently independent state of South Sudan) since the disease was first reported in 1908. Recent data about the genetic identification of the parasite in the countries in both humans and animals and its importance for future control programs is discussed.
