Signs
Ancylostoma tubaeforme infection may lead to dermatitis, anemia, weight loss, and pulmonary lesions.
Life cycle
Ancylostoma tubaeforme larvae may infect a host through oral ingestion or through skin lesions.
Larvae ingested by the host pass through the esophagus into the stomach. From there, they burrow into the lining of the stomach and duodenum, and develop into their adult form. The adult hookworms then burrow back into the lining of the stomach and release their ova into the gastrointestinal tract.
Larvae that infect a host by penetrating the skin migrate to the stomach by first traveling through the lungs, up the trachea, and down the esophagus. From there, the larvae develop into adult hookworms, burrow back into the stomach lining, and release their ova into the gastrointestinal tract.
The prepatent period, the time between infection and when larvae can be detected, is 22–25 days.
Diagnosis
Diagnosis of A. tubaeforme infection is done through routine fecal flotation.
Treatment
Infections are typically treated with oral anthelmintics such as fenbendazole, or topical treatments such as selamectin.
