  • To the Editor, During recent years some exotic animals have been introduced as laboratory animals1 or pets in domestic environments, increasing the risk of exposure to many unknown potential allergens which could cause respiratory allergy symptoms in the owners.2 In the case of hamster, there are various species with the same generic name but belonging to different rodent genus coming from different regions of the world without evidence of a clear cross reactivity among their allergens.2, 3, 4 Now in Spain it is possible to find different types of hamsters as pets, the most common is the golden or Syrian hamster (Mesocricetus auratus), there are dwarfs hamsters: Chinese hamster (Cricetus griseus), Siberian or Russian hamster (Phodopus sungourus), Roborowski (Phodopus roborowskii), and apparently the cross reactivity found among their epithelium allergens is very low. We present three cases with different sensitisations: First case: A 41-year-old woman with well-controlled pollinic asthma who began to suffer from daily asthmatic episodes and bad response to treatment with inhaled corticosteroids and B2, after buying a Russian hamster (Phodopus sungorus) (RH) for her child. Skin prick test (SPT) with extract from RH epithelium was positive (8x7mm), however it was negative against Syrian hamster (SH) epithelium. Histamine control: 4 x 5mm. Serum specific IgE level was very high against RH epithelium 90.1kU/L and urine 86.3 kU/L, and very low against SH allergenic sources (epithelium: 0.7 kU/L; urine: 0.5 kU/L). SDS-PAGE-Immunoblotting showed an intense IgE binding band of ca. 21 kDa in RH epithelium extract and a high IgE binding area of ca. 18...
