The correct Answer is:
To answer the question of which human parasites require mosquitoes to complete their life cycle, we can follow these steps: ### Step 1: Identify the Parasites First, we need to identify the parasites mentioned in the question. The common human parasites that are often discussed in relation to mosquitoes include: - Ascaris - Leishmania - Dirofilaria - Plasmodium (specifically Plasmodium ovale) ### Step 2: Understand the Life Cycle of Each Parasite Next, we will analyze the life cycle of each parasite to determine if a mosquito is involved: - **Ascaris**: This is a roundworm that does not require a mosquito. It has a direct life cycle and typically involves soil as a medium. - **Leishmania**: This protozoan parasite is transmitted by sandflies, not mosquitoes, so it does not require mosquitoes for its life cycle. - **Dirofilaria**: This is a genus of parasitic roundworms that can be transmitted by mosquitoes. It is important in veterinary medicine, particularly in dogs, but can affect humans as well. - **Plasmodium ovale**: This is a protozoan parasite that causes malaria and requires mosquitoes (specifically Anopheles mosquitoes) to complete its life cycle. The mosquito acts as a vector for the parasite. ### Step 3: Conclusion Based on the analysis: - The parasites that require mosquitoes to complete their life cycle are **Dirofilaria** and **Plasmodium ovale**. ### Final Answer The human parasites that require mosquitoes to complete their life cycle are **Dirofilaria** and **Plasmodium ovale**. ---
