Hookworm Infections

This micrograph depicts a hookworm rhabditiform-staged larva, which represents its early 1st to 2nd stage of development. This unstained micrograph reveals the Ancylostoma duodenale hookworm's mouth parts; Mag. 125X. This micrograph shows a hookworm egg from an undetermined species of origin. This embryonated egg is indistinguishable between the Ancylostoma duodenale or Necator americanus hookworm. This micrograph depicts a hookworm rhabditiform larva, which represents its early, noninfectious immature stage. This micrograph depicts the buccal cavity morphology of a hookworm, during its rhabditiform, early noninfectious larval stage. The human hookworms include two nematode (roundworm) species, Ancylostoma duodenale and Necator americanus. This patient presented with a hookworm infection involving the toes of the right foot, which is also known as “ground itch”. This enlargement shows hookworms, Ancylostoma caninum attached to the intestinal mucosa. This micrograph depicts the mouth parts of rhabditiform staged larvae of a hookworm (Lt), and strongyloides (Rt); Mag. 500X. This photomicrograph reveals a hookworm egg undergoing the process of cellular division. This micrograph depicts the tail tip of a hookworm (Lt), and a Strongyloides (Rt) filariform infective stage larvae. This micrograph depicts a hookworm (Lt), and a Strongyloides (Rt) filariform infective stage larvae. This diagram depicts the various stages in the life cycle of the Strongyloides stercoralis nematode. This child with hookworm shows visible signs of edema, and was diagnosed with anemia as well. This micrograph confirms the presence of hookworms in a host’s intestines where they will reside while obtaining nutrients. This diagram represents the diagnostic algorithm which is implemented when diagnosing hookworm infections.
