Ancylostomatoidea Structure and Function

General Life-Cycle

• Like that of the Strongyloidea, but infection can be by ingestion and/or skin penetration

• Ancylostoma in myositis
• Ancylostoma and Uncinaria in skin infections

The hookworms are 1-2cm long bursate nematodes. They are easily identified under the microscope, as they have a large buccal cavity with teeth, and the mouth points dorsally. Some have teeth around the rim of the mouth which can be used for identification, and which are used to embed the head deeply into the mucosa of the small intestine. The life-cycle is typical for the superfamily.

As with all hookworms, the L3 can penetrate the skin. A protective immunity develops, and so enteric disease is largely confined to pups. Some dogs develop a hypersensitivity, leading to a pedal dermatitis which can affect all ages.
