Seasonal rhinitis in a cat sensitized to Japanese cedar (Cryptomeria japonica) pollen.
A cat showing seasonal allergic symptoms of rhinitis was examined for reactivities to Japanese cedar (Cryptomeria japonica, CJ) pollen allergen by intradermal skin test (IDST), Prausnitz-Kustner (P-K) test, and lymphocyte blastogenic response. In IDST for 26 common allergens. the cat showed a positive reaction to CJ pollen allergen. P-K test using CJ pollen allergen also showed a positive reaction, indicating the presence of serum IgE specific to CJ pollen. In the lymphocyte blastogenic response, the stimulation index in the presence of CJ pollen allergen was 2.4. These data suggested that the seasonal rhinitis observed in the cat was caused by the sensitization to CJ pollen allergen.
