Thirty-Seven Human Cases of Sparganosis from Ethiopia and South Sudan Caused by Spirometra Spp.

Eberhard ML, Thiele EA, Yembo GE, Yibi MS, Cama VA, Ruiz-Tiben E - Am. J. Trop. Med. Hyg. (2015)

Bottom Line: All 37 specimens were identified on microscopic study as larval tapeworms of the spargana type, and DNA sequence analysis of seven confirmed the identification of Spirometra sp.Age of cases ranged between 7 and 70 years (mean 25 years); 21 (57%) patients were male and 16 were female.The presence of spargana in open skin lesions is somewhat atypical, but does confirm the fact that populations living in these remote areas are either ingesting infected copepods in unsafe drinking water or, more likely, eating poorly cooked paratenic hosts harboring the parasite.

Clinical presentation of a case of sparganosis illustrating the progression of the emergence of the spargana. (A) Initial lesion with minute white tip of worm. (B) Protrusion of larger portion of larva. (C) Mass of “hanging” worm. (D) Lesion after final emergence of larva. These images show the remarkable similarity to the appearance of emergence of Guinea worm.
