Microfilaria of Loa loa
First, this is a sheathed microfilaria. The cephalic space and empty caudal space were evident. The sheath did not stain pink like the one of B. malayii. The nuclei extends to the end of the interior end. The morphologic features and the geographic location were consistent with Loa loa.

Filaria is sheathed, body nuclei extend to the tip of the tail. It looks like Loa loa.
Thick blood film, allowing microfilaria of Loa loa depicting the ghost of the sheath and the nuclei coming to the tip of the tail. Microfilariae of Loa loa have body nuclei that are continuous from tip to tail. This distinguishes them from microfilariae of Wuchereria bancrofti and Brugia malayi which have extended sheaths on both ends.
I thank Dr. BOBBI PRITT for the initiative concerning the proposed cases.
