Question

BlackTom AI · Accepted Answer

Question restatement: A useful treatment for parasitic nematode infections is:

Option a) acyclovir: This antiviral drug targets herpesviruses and is not used for nematodes. It’s effective against viral infections, not parasitic worms, so it does not address nematode infections.

Option b) artemisinin: Artemisinin derivatives are primarily used for malaria, caused by Plasmodium species, which are protozoan parasites, not nematodes. While it is an antiparasitic, it is not the standard treatment for nematode infections, making this option inappropriate for the question’s nematode focus.

Option c) ivermectin: Ivermectin is a broad-spectrum antiparasitic agent effective against many nematodes (roundworms), including soil-transmitted helminths and onchocerciasis. It works by binding to glutamate-gated chloride channels in nematode nerve and muscle cells, causing paralysis and death of the parasite. This makes it a well-known, useful treatment for parasitic nematode infections.

Option d) penicillin: Penicillin is an antibiotic targeting bacterial cell wall synthesis, not parasites. It has no activity against nematodes and would not treat nematode infections.

Summary: Among the choices, ivermectin is the appropriate and commonly used therapy for parasitic nematodes due to its mechanism and broad efficacy, whereas the other options are either for different pathogens or have no relevant anthelmintic activity.
