Raillietina tetragona

Raillietina tetragona is a type of tapeworm, specifically known as a cestode that is an internal parasite of chickens. R. tetragona is a 100-250 mm (4-10 in) long flattened, segmented, ribbon-shaped worm that invades the chicken's gastrointestinal system, most commonly found in the lower intestines.

Life cycle
R. tetragona has an indirect life cycle, using beetles as intermediate hosts. Chickens become infected by consuming the R. tetragona eggs shed in the feces of infected chickens or infected ants.
