Necator americanus, Hookworm

Necator americanus is a hookworm that can be detected in stool. It is an intestinal worm and is not considered a normal part of the dog’s gut microbiome. Unlike the more typical canine hookworms, Necator americanus is mainly known as a human hookworm, so detection in a dog sample should be interpreted carefully. A finding may reflect exposure to contaminated soil, sand, grass, or environments where infected faeces may have been present, especially warm, moist, or shaded ground. Hookworm larvae are known for their ability to enter through the skin, but in dogs this specific species is not considered a typical established hookworm infection. Relevant findings may be associated with digestive irritation, altered stool quality, dark or bloody stool, weakness, reduced appetite, or signs related to blood loss. A positive finding may be useful to review with a veterinarian, especially if digestive signs, possible exposure to contaminated ground, or signs of blood loss are present.
