Red Stomach Worm
The red stomach worm is a parasitic nematode that infects the stomach of pigs. Red stomach worms are typically 6 to 10 millimeters long. Females can lay up to 10,000 eggs per day, and like the hookworm, they are transmitted through the host animal's feces. Red stomach worms also flourish in warm, humid climates. These worms cause anaemia and oedema in their host(s), which can lead to death. Red stomach worms also have no formal respiration system and breathe through diffusion. Diffusion is a process in which oxygen enters through the worm's skin while carbon dioxide and other waste products exit from it.
