text: Adult hookworms inject anticoagulants, antiplatelet aggregating agents, and connective tissue hydrolases into the attachment site (Cappello et al., 1995; Ledizet et al., 2005), which results in a free flow of host blood into the intestinal lumen, some of which is ingested by the adult hookworms, which then lyse the red blood cells (Don et al., 2004) and degrade the ingested hemoglobin by an orchestrated cascade of hemoglobinases, to be used by the worms as an energy source (Williamson et al., 2004).
