Sheathed microfilaria, it looks like the nuclei extend to the tip of the tail in a single row: Loa loa.
20 years ago I spent some time hitch hiking in Africa. One of my tropical medicine professors wondered how I knew where Calabar is. “I’ve been there.”

I like for microfilaria and I'm going to guess Wucheria bancrofti as I'm going to interpret as sheathed, nuclei not to the tip of the tail and a smallish head -- this is a guess as I don't think I've ever had to diagnosis primarily a case in San Francisco.

Brugia malayi. "It has a sheath that picks up Giemsa stain. Loa loa and W. bancrofti have sheaths,but they do not stain with Giemsa stain."

Tough one. The Giemsa picks up the sheath really well but the posterior end has a single column of nuclei that extends to the tip. Not Wucheria because the Giemsa should stain the innerbody bright pink. Not loa loa because the sheath shouldn't stain with the Giemsa. Brugia malayi?
