Cestodes, intestine of a swordtail Xiphophorus hellerii

Video of microscopic examination of intestinal tissue from a swordtail (Xiphophorus hellerii) infested with cestodes. Careful observation at necropsy may reveal a pale intestine. Often the cestodes are grossly visible when the intestine is placed on a slide. Unstained wet mount; magnification, 100×.
