ABSTRACT: This study provided new data in the area of cross-reactivity for Pacific white shrimp (Litopenaeus vannamei). Although the cross-reactivity between the most prominent allergenic proteins of shrimp and other crustaceans has been extensively studied, few data are showing the frequency of arthropod-shrimp Litopenaeus vannamei cosensitization in an in silico analysis. A comparative analysis of “typical and non-typical” shrimp L. vannamei allergens with other species was achieved, revealing new allergens and previously characterized shrimp allergens, which validated the comprehensive identification approach used in this study. Importantly, up to 192, amino acid sequences were identified that had matches to shrimp L. vannamei allergens that matched allergenic proteins in mites, insects, fish, bacteria, mammals, birds, and plants.
