Question
Which among the following parasitic helminths is a nematode and has zoonotic transmission?
The correct answer is
Trichinella spiralis
The question asks us to identify which among the given parasitic helminths is a nematode and has zoonotic transmission.
- Let's first understand the characteristics of each option:
- Taenia saginata: This is a cestode (tapeworm) that can be acquired from undercooked beef.
- Trichinella spiralis: This is a nematode (roundworm) known to cause trichinosis. It is transmitted to humans through the consumption of undercooked or raw meat, especially pork, which contains the encysted larvae, making it zoonotic.
- Fasciola hepatica: This is a trematode (fluke) that causes fascioliasis, usually obtained from ingesting contaminated water or aquatic vegetation.
- Fasciolopsis buski: This is also a trematode and is known to cause fasciolopsiasis, contracted through contaminated water plants.
- The question specifies that we are looking for a nematode with zoonotic transmission. Based on the information above, we can identify Trichinella spiralis as the nematode that transmits zoonotically through meat consumption.
Thus, the correct answer is Trichinella spiralis.
