Necator decretus

Necator decretus is a species of nematode belonging to the family Ancylostomatidae. It is a type of parasitic worm that primarily affects the gastrointestinal tract of its host.

Overview

Necator decretus is one of several species within the genus Necator, which are commonly referred to as hookworms. These parasites are known for their hook-like mouthparts, which they use to attach to the intestinal wall of their host.

Life Cycle

The life cycle of Necator decretus begins when the eggs are excreted in the feces of an infected host. These eggs then hatch into larvae in the soil. The larvae can survive in the soil for several weeks, waiting for a new host to come into contact with them. Once a host is found, the larvae penetrate the skin and are carried through the bloodstream to the lungs. From the lungs, they are coughed up and swallowed, ending up in the small intestine where they mature into adult worms.

Pathology

Infection with Necator decretus can lead to a condition known as hookworm disease. Symptoms of this disease can include abdominal pain, diarrhea, weight loss, and anemia. In severe cases, hookworm disease can lead to developmental delays in children and can be fatal if left untreated.

Treatment and Prevention

Treatment for Necator decretus infection typically involves the use of anthelmintic drugs, such as mebendazole or albendazole. Prevention strategies include improved sanitation and the wearing of shoes in areas where the parasite is common.
