A genus of parasitic roundworms that primarily infect the cecum and intestines of birds, particularly poultry like chickens and turkeys.
From Greek hetero- (different) + akis (point or sharp part), referring to the unequal or differentiated structures of the worm. This is a Linnaean genus name combining classical Greek roots.
Heterakis became a major concern in the 1950s when researchers discovered it transmitted the protozoan that causes blackhead disease in turkeys, leading to the first major antiparasitic campaigns in industrial agriculture and fundamentally changing how we farm birds.
