Answer to Case 129

Answer: Wuchereria bancrofti.

The main features that support the diagnosis are:
1. presence of a sheath (faintly staining)
2. nuclei do not extend to the tip of the tail




Some viewers commented that this could be Brugia malayi since the sheath stains with giemsa. However, I find this to be a less-reliable feature. More important are the characteristics of the nuclei. The nuclei of B. malayi extend to the tip of the tail, unlike those of W. bancrofti.

Great job on a tough case!

Wuchereria Bancrofti stains Giemsa stain too! Brugia Timori is the one that doesn't stain with Giemsa stain!
