1.which parasite enter the body by piercing the skin
Some examples of parasites that enter the body by piercing the skin include:
1. Parasitic roundworms (Nematodes): Certain types of nematodes, such as hookworms (Ancylostoma duodenale and Necator americanus), enter the body by penetrating the skin, usually through bare feet contacting contaminated soil or sand.
2. Leeches: Leeches are blood-sucking parasites that have teeth-like structures to pierce the skin and feed on blood. They are usually encountered in freshwater environments.
3. Ticks: Ticks are external parasites that attach to the skin and feed on blood. They have specialized mouthparts that allow them to pierce the skin and remain attached for an extended period.
4. Fleas: Fleas are small, wingless insects that also feed on blood. They can jump onto a host, typically a mammal, and their strong mouthparts pierce the skin to obtain blood meals.
It is important to note that preventing contact with contaminated areas, wearing protective clothing, and using appropriate insect repellents are some measures to reduce the risk of parasitic infections from skin-penetrating parasites.
