HAMSTER DANDER ALLERGY
Hamsters are rodents in the Cricetidae family of rodents. This family of animals includes voles and lemmings. Although very similar in size, hamsters and gerbils are not closely related, gerbils are more closely related to mice.
There is only 1 allergen associated with an allergy to hamsters, this includes their hair, dander (which is flakes of dry skin), urine and saliva.
Mes a 1 are lipocalin proteins, in other animal dander allergies this is the protein that most individuals react to. These proteins transport molecules like lipids and steroids around the body.
Allergy to hamster dander is strongly strongly associated with allergic rhinitis as well as asthma, rhinoconjunctivitis and atopic dermatitis.
A hamster allergy can be strongly linked to other animal allergies due to the lipocalin proteins. There is evidence of cross reactivity due to this protein with cockroaches, cows, dogs, guinea pigs, horses, cats, mice, rabbits and rats.
These allergen lists are not exhaustive, the most up to date information is on the Cross Reactivity Tool.
