Allergy to Black Bass Fin and Carp

Anaphylaxis to European Perch (Perca fluviatilis) Due to a-Actin Protein

“…We identified an a-actin protein with a molecular mass of 31 kDa instead of 42 kDa [7,8]. Similar findings have been reported by other authors [9] and could be explained by a-actin degradation.…”

“…It was also involved as a cross-reactive allergen between fish and poultry (fish-chicken syndrome) [7]. ß-Actin has been described as a fish allergen in a case of contact allergy with black bass fin [8].…”

Fish Allergy: A Review of Clinical Characteristics, Mechanism, Allergens, Epitopes, and Cross-Reactivity

“…A minority of patients are selectively allergic to specific fish species, well tolerating other various fish species. 83 It is common for clinical cross-reactivity between different fish species, and most patients sensitized to one type of fish are also allergic to other types of fish. Van Do et al investigated that the most cross-reacting allergens were cod (Gad c 1), salmon (Sal s 1), pollack (The c 1), wolfish, and herring, but halibut, mackerel, flounder and tuna were the least allergenic.…”

“…Parvalbumins from different fish species usually show cross-reactivities, with a general probability of 50%. , Most fish-allergic patients show significant clinically relevant cross-reactivity, and they generally are allergic not only to a single species of fish but rather to a range of different fish species. A minority of patients are selectively allergic to specific fish species, well tolerating other various fish species …”
