In 1967, an elderly Vietnam War veteran was diagnosed with malaria and successfully treated, but later in 2003, he has his legs and testicles destroyed by Lymphatic filariasis caused by Wuchereria bancrofti worms.
The life of the parasite can be traced through the black fly and the human hosts in the following steps: [13] [14] A Simulium female black fly takes a blood meal on an infected human host and ingests microfilaria. The microfilaria enter the black fly's gut and thoracic flight muscles, progressing into the first larval stage (J1.).
The worm has a long pseudosegmented body with a short neck. The proboscis is long with a sac-like receptacle and possesses 25 circular longitudinal rows of between 8 and 12 hooks at the anterior region, and 10 rows of 8 to 16 spines at the posterior region. The two testes are oval and there are eight cement glands. [24]

The "blind" in blind-worm refers to the lizard's small eyes, similar to a blindsnake (although the slow-worm's
The planarian has a soft, flat, wedge-shaped body that may be black, brown, blue, gray, or white. The blunt, triangular head has two ocelli (eyespots), pigmented areas that are sensitive to light. There are two auricles (earlike projections) at the base of the head, which are sensitive to touch and the presence of certain chemicals.
