Front 20

The microfilaria of this parasite are usually sparse in the blood, have a crescent shaped body, head is blunt (no taper) with a cephalic hook, and the tail is curved resembling a "button hook".

Back 20

Dipetalonema reconditum

Front 21

This parasite is found in the caval veins, right heart chambers, and pulmonary arteries of dogs and some other hosts. They are long, thin, whitish, and the males have a coiled tail.

Back 21

Dirofilaria immitis

Front 22

The microfilaria of this parasite are numerous in the blood, with a straight body, a slightly tapered head, and a straight tail.

Back 23

Onchocerca species

Front 24

This genera of parasite is free in the abdominal cavity of horses and ruminants, and can occasionally be found in the eyes or scrotum. They are long, thin, white worms. The microfilaria are sheathed.

Back 24

Setaria species

Front 25

This parasite is found in the lymphatics or dermis of cattle, and are about 1/4 of an inch long.
