Question

Name the parasite whose microfilariae have a sheath with no nuclei at the tail end.

• A. Wuchereria Bancrofti
• B. Brugia malayi
• C. Loa loa
• D. None

Answer 1

The Correct Option is A

In microbiology, it's crucial to identify parasites based on their specific characteristics. In this case, we are looking for a parasite whose microfilariae have a sheath with no nuclei at the tail end. The options given are:

• Wuchereria Bancrofti
• Brugia malayi
• Loa loa
• None

The correct answer is Wuchereria Bancrofti. Here's why:

Wuchereria bancrofti is a well-known parasitic worm responsible for lymphatic filariasis. One of the distinguishing features in its identification is the structure of its microfilariae. These microfilariae are sheathed, which means they possess a protective covering. Notably, the nuclei within the microfilariae of Wuchereria bancrofti do not extend to the tip of the tail, which matches the description given in the question.

To reiterate, the absence of nuclei at the end of the tail in the sheathed microfilariae is a characteristic specific to Wuchereria bancrofti, setting it apart from other similar parasites.
