Illustrated in the photomicrograph is the tail portion of an adult worm of a filarial nematode as it may be observed in a peripheral blood smear. These worms measure up to 300 um in length and commonly inhabit the lymphatics. This nematode species more commonly involves the lymphatics of the inguinal region resulting in swelling below the knee in what is known as elephantiasis. The species indicated in this exercise can be presumptively determined by the orientation of nuclei within the tail sec...
