Abstract

|
A study carried out in order to confirmed of aetiology and pathogenicity of anisakiasis due to anisakis-like larvae in marine fishes and marine mammals.
The fishes subjected which were god (Gadus morhua Macrocephala) and Therragra chalcogramma. They were purchase from fishery market in Seoul.
Larvae isolated were classified into anisakis (type 1), terranova (type A). The morphological characteristics of each type of larvae are summarized as follows;
Anisakis (type 1) has longer ventriculus and short tail. The average body length, width, esophagus and tail are 25.6mm, 0.51mm, 2.29mm, 0.99mm, and 0.14mm. respectively. Indices α, β, and γ are 50.3, 11.17 and 182.8 respectively.
Terranova (type A) has short ventriculus and intestinal caecum. The average body length, width, esophagus, ventriculus, intestinal caecum and tail are 24.6mm, 0.55mm, 2.44mm, 0.63mm, 0.50mm and 0.1mm respectively. Indices α, β, γ and Y are 44. 7, 10.0, 246 and 49. 2 respectively.
Pathohistological findings shown, as follows;
Histologically, the wall of the stomach was slightly found all layers with edema, inflammatory reaction. The mucosa may show atrophy and erosion, sub mucosa glands show proliferating fibroblast, necrosis and abscess.
Cross-section of the parasite in the sub mucosa of stomach showing the esophagus and intestine portion of larva and slight leukocyte infiltrate in the surrounding tissue without eosinophilic infiltration.
