Despite considerable advances in chemotherapy and control, hookworms rank amongst the most widespread of soil-transmitted intestinal helminth parasites and affect a significant proportion of the world population (approximately 900 million people) mainly in the tropics and sub-tropics (Bundy et al., 1991).
