Old World hookworm includes which species?

Explanation:
Old World hookworms are the species historically identified in humans on continents like Europe, Asia, and Africa. Among human infections, Ancylostoma duodenale is the classic Old World hookworm. The other human hookworm, Necator americanus, is often described in connection with the New World, and though it occurs worldwide today, the traditional Old World association is with A. duodenale. Ancylostoma caninum is a dog hookworm, and Toxocara canis is a dog roundworm, not a human hookworm. So, Ancylostoma duodenale is the correct Old World hookworm.
