Anisakidosis: report of 25 cases and review of the literature.

Abstract: Anisakidosis (previously known as anisakiasis) is a disease caused by the accidental ingestion of larval nematodes (Anisakis and sometimes Pseudoterranova) in raw fish Two groups of patients are studied: 5 clinical cases and 20 serological diagnoses 55 French cases are already published Most of them complained of acute symptoms, which occurred within 12 h of eating the seafood meal--epigastric pain, occlusion, diffuse abdominal pain, and appendicitis Larvae were attached to the gastric mucosa (25 cases), including an inflammatory response (erythema, oedema ulceration) Diagnosis of anisakiasis is made by gastroscopy which allows removal of the worms, and cures the patients In gastro-intestinal tract X-rays, oedema in the mucosa, pseudo tumour formation, and filling defects (worm) were observed In chronic infections, cases with intermittent feelings of ill health and abdominal pain, lasting from several weeks to months, were misdiagnosed as another intestinal disease Positive serological reactions are helpful, and surgery is necessary for resection of the lesion; diagnosis is made histologically by an eosinophilic granuloma, and the presence of a larva with Y shaped lateral cords Infestation rate is high in fishes: cod (88%), rock fish (86%), herring (88%), salmon, mackerel Public health education should discourage the eating of raw fish Thorough cooking to 70 degrees C or adequate freezing to -20 degrees C for 72 h are the best preventive measures Such legislation is only in force in the Netherlands, where cases have decreased dramatically

Infection status of anisakid larvae in anchovies purchased from local fishery market near southern and eastern sea in Korea

Abstract: A survey was carried out on the larval anisakis in anchovies (Engrauris japonica) which were caught from April to June in 1993 at the southern and eastern sea in Korea. Anisakids in anchovies were morphological classified into Anisakis type I and II and Contracaecum type B and C, after fixation in 70% alcohol and clearing in lactophenol. A total of 171 larval anisakids were collected from 150 anchovies (6.9%) out of 2,180 examined. The infection rates showed no relation with length of the anchovies. The numbers of anisakids by organs of anchovies were 96 (56.1%) from the muscle, 65 (38.0%) from the omentum, 7 (4.1%) from the intestine, 2 (1.7%) from the stomach and 1 (0.6%) from the testis. Infection rates of anchovies with anisakids by localities were 5.1% at Taebyon, 8.0% at Sokcho and 9.2% at Chungmu. The larval anisakids in anchovies may infect humans who often eat raw anchovies.
