During the studies on the esophagogastric ulcers in swine, Anisakis type larvae were found associated with stomach lesions.
1. Of the 1,531 pigs examined, 11(0.7%) were infested with the parasite in the stomach.
2. The parasite was identified as Anisakis type I larvae, according to the morphological characteristics.
3. On gross examination, the parasites were seen penetrating gastric mucosa, resulting in hemorrhagic ulcers.
4. Main histopathological features were edema, massive eosinophilic infiltrations around the parasite, necrosis and perivascular eosinophilic accumulations in the submucosa.
