I agree with the Loa loa.

Microfilaria in blood, no sheath with Giemsa stain, nuclei that extend to tip of tail and blunt ended tail = Loa Loa

This would have been picked up in Cameroon not Spain I imagine as Loa Loa is the tropical African eye worm, contracted from a bite by the vector Chrysops spp. (mango or deer flies).
