#intestinal parasite

• Hookworm — A parasitic nematode worm of the genus Ancylostoma, small in size, with a dorsally curved anterior end and a well-developed buccal capsule equipped with chitinous hooks or teeth. Attaching itself to the mucosa of the duodenum or small intestine in humans and certain animals, this hematophagous organism causes tissue lesions, local microscopic hemorrhages, and severe states of anemia.
• Ankylostomiasis — A parasitic disease caused by the presence of nematode worms of the genus Ancylostoma in the small intestine. This condition manifests through severe gastrointestinal disturbances, digestive mucosal lesions, chronic microscopic bleeding, and a marked iron-deficiency anemia due to the hematophagous nature of the parasite.
• Ascaridiosis — A parasitic infectious disease, widespread in humans and animals, caused by infestation with roundworms of the genus Ascaridia or Ascaris. This parasitic condition develops primarily within the small intestine, where the presence of parasites causes severe digestive disorders, acute abdominal pain, malnutrition states, and allergic reactions due to released toxins.
• Ascaris — A genus of large parasitic cylindrical nematode worms in the Ascarididae family, which inhabit the small intestine of humans and other mammals during their adult stage. The typical and most well-known species is Ascaris lumbricoides, the etiological agent of ascariasis, a parasitic organism structurally adapted to the enteric environment, capable of causing severe digestive, respiratory, and nutritional disorders in the absence of proper treatment.
