Bogni Dario talks about anisakis: what it is and how to treat it

Bogni Dario explains, the Anisakis simplex is a parasite about 2 centimeters long, whose larvae live in the digestive system of many marine species such as hake, cod, tuna, octopus, cuttlefish, squid and also in some crustaceans like crabs and lobsters. Which fish are most affected The fish species described as hosts of the Anisakis simplex in our environment are: Cod, sardines, anchovies, herring, salmon, pollock, hake, whiting, halibut, turbot, mackerel, bonito and horse mackerel. Among the cephalopods, squid, octopus and cuttlefish. Anisakis can also be found in shellfish. There can be a frequency of parasitization between 23 and 80% of commercially sold fish. There may also be parasitization in freshwater fish. Dario Bogni tells how we come into contact with anisakis The route of entry of this parasite into our body is the intake of raw, salted, marinated, smoked or undercooked fish. Diseases it can cause in humans Anisakiasis is caused by infestation of fish contaminated with anisakis or other related parasites (Pseudoterranova Phocanema, Diphyllobothrium latum, Nanophyetus salmicola, Eustrongylides, etc.). This parasite is found in the muscles of fish, especially on the Pacific coast. The hosts of these parasites are seals and other aquatic mammals. Clinic Within 2 days of eating infected fish, epigastric pain, dry throat, and overheating of the mouth and esophagus appear. Colic abdominal pain of 10 minutes duration, with vomiting, diarrhea, vomiting, urticaria, etc. Endoscopy shows the edematous and hemorrhagic intestine. Sometimes bowel invasions, perforation, and eosinophilia can occur, with a picture similar to an acute abdomen (such as appendicitis). Diagnosis of Anisakiasis Eosinophilia (increased eosinophils in the white blood cell count) may appear in the blood. There may also be hidden blood in feces, says Bogni Dario. An endoscopy of the proximal intestine should be performed, viewing the larvae. There is no diagnostic test for anisakiasis. Treatment Endoscope removal of larvae. If it appears as an acute abdomen, surgical intervention. The efficacy of anthelmintics has not been demonstrated.
