The guinea-worm may be described as a nematode measuring from one to six feet in length, having a thickness of 1/10th of an inch.
The guinea-worm (Filaria medinensis) is a very troublesome parasite, which sometimes grows to a length of three feet.
On this he started up on two sticks, for he is doubly lame, having the guinea-worm in both legs, and went away hurriedly.
The guinea-worm having been known from the earliest times, it is not surprising that its true nature long remained a mystery.
Among the many advances of modern helminthology, the discovery of the true source of the guinea-worm is not the least important.
