Proteolytic enzymes from the dorsal pharyngeal gland are released into the buccal cavity which aid in digestion.

The worms clamp onto the mucosa abrading the surface and sucking the blood. Intestinal phase: Adult worms are usually restricted to the anterior third of the small intestine, but where infections are very heavy they can occupy the whole length of the small intestine. This is rarely symptomatic, except when there is a heavy infection, when it can result in pneumonitis, and can also cause a cough and a sore throat. This causes local hemorrhaging at the site. Pulmonary phase: This occurs during the period when the larvae are bursting out of the capillaries in the lungs into the alveolar spaces.

There are three pathological phases to hookworm infections:Ĭutaneous or invasive phase: When larvae initially penetrate the skin they can cause irritation and itching and if they fail to locate a blood capillary they can wander through the skin causing a condition known as cutaneous larval migrans, leaving a track visualized under the skin by the presence of the host inflammatory reaction. The larvae migrate from your lungs to your windpipe and are then swallowed and carried back down to your small intestine. Unlike ascarids, another form of parasitic roundworm, hookworms do not usually cause pneumonia. Once larvae have broken through your skin, they enter your bloodstream and are carried to your lungs.

Hookworm disease is a parasitic disease caused by the entry of larvae (immature form) of the hookworm, most commonly, Necator americanus, into a human host.
