Simultaneous Detection and Prevalence of Allergens in Anisakis Species Isolated from Marine Fishes

초록

This study was conducted to develop a multiplex reverse transcription (RT) PCR for the detection of Anisakis allergens and to investigate the relationship between allergen profiles and anisakid larvae isolated from Scomber japonicus, Trichiurus lepturus, and Conger myriaster in Korea. The species of Anisakis was determined using Anisakis pegreffii-specific PCR and restriction fragment length polymorphism analysis. The prevalence and profiles of five Ani s allergens were examined by multiplex RTPCR. A. pegreffii and Anisakis typica accounted for 97.1 and 2.9%, respectively, of the 140 larvae examined. In A. pegreffii, allergen prevalence was 41.2% for Ani s 1, 72.1% for Ani s 2, 69.9% for Ani s 3, 86.7% for Ani s 4, and 93.4% for Ani s 5. Most A. pegreffii larvae had multiple allergen profiles, and 80.7% of A. pegreffii carried both Ani s 4 and Ani s 5, which are heat resistant allergens. Fifty-two to 65% of A. pegreffii isolated from S. japonicus and C. myriaster carried all five Ani s allergens.
