Question

Ground itch is due to larvae of

• A. Ancylostoma
• B. Enterobius
• C. Trichuris
• D. All of the above

Answer 1

The correct option is A Ancylostoma

Hookworm's larval invasion of the skin can produce a skin disease called cutaneous larva migrans also known as creeping eruption. The hosts of these worms are not human and the larvae can only penetrate the upper five layers of the skin, where they give rise to intense, local itching, usually on the foot or lower leg, known as ground itch. This infection is due to larvae from the A. braziliense hookworm. The larvae migrate in tortuous tunnels between the stratum basale and stratum corneum of the skin, causing serpiginous vesicular lesions. With advancing movement of the larvae, the rear portions of the lesions become dry and crusty. The lesions are typically intensely itchy.

So, the correct answer is 'Ancylostoma'.
