Abstract Background: IgE reactivity to fish allergens in atopic dogs, which are used as models for food allergy, has not been elucidated to date. We investigated IgE reactivity to crude extracts and purified allergens derived from the Pacific cod (Gadus macrocephalus) in atopic dogs to identify the allergenic proteins of cod.Results: The levels of specific IgE to crude cod extracts were measured in the sera of 179 atopic dogs, including 27 dogs with cod allergy, using enzyme-linked immunosorbent assay (ELISA). Specific IgE to crude cod extracts were present in 36 (20%) of the 179 atopic dogs and in 12 (44%) of the 27 dogs with cod allergy. The allergens in crude cod extracts were analyzed by ELISA, immunoblotting, and liquid chromatography-tandem mass spectrometry. In allergen component analysis, IgE reactivity to tropomyosin and enolase was observed in the sera of dogs with cod allergy. IgE reactivity to parvalbumin, collagen, and tropomyosin was evaluated using the sera of atopic dogs that tested positive for specific IgE to crude cod extracts. Among the 36 dogs with IgE reactivity to crude cod extracts, 9 (25%), 14 (39%), and 18 (50%) dogs tested positive for specific IgE to parvalbumin, collagen, and tropomyosin, respectively.Conclusions: The IgE reactivity to cod allergens observed in dogs was similar to that in humans, and this finding further supports the use of atopic dogs with fish allergy as a model for fish allergy in humans.

Eggs of the Pacific cod (Gadus macrocephalus Tilesius) were held from fertilization to completion of hatching in various combinations of constant salinity (19–31‰) and temperature (2–10 C). Hatching occurred in all salinities and temperatures, and survival was highest at the lower levels of both factors. A direct and approximately linear relationship was found between rate of development and temperature within the temperature range employed. At each temperature the length of the incubation period was increased at lower salinities. It is suspected that eggs were subjected to hypoxial conditions in the experiments, a circumstance considered to have depressed survival rate over all experimental combinations. There was, in general, an inverse relationship between salinity and temperature with respect to both size of larvae produced and the duration of the hatching period. Calculated response isopleths suggest that eggs of Gadus macrocephalus are euryhaline, and that maximum hatching success may be found in the vicinity of 19‰ S and 5 C. Changes of 1 C were calculated to be equivalent in effect on hatching success to a change of about 12‰ S.
