Microfilaria of Wuchereria bancrofti, from a patient seen in Haiti.  Thick blood smears stained with hematoxylin.  The microfilaria is sheathed, its body is gently curved, and the tail is tapered to a point.  The nuclear column (the cells that constitute the body of the microfilaria) is loosely packed, the cells can be visualized individually and do not extend to the tip of the tail.  The sheath is slightly stained with hematoxylin.
