EPIDERMAL DERIVATIVES OF PETS

The epidermal derivatives of pets are released from saliva, dander and urine of dogs and cats, but also of birds and cockroaches. Once dried and fragmented, they remain suspended in airborne dust.

In Italy, a significant source of allergens in indoor environments is represented by domestic animals, in particular by the cat. The cat is a risk factor for allergies not only in the home, but also in offices, schools and probably in all community environments.

The most significant allergen is identified with the abbreviation Fel d 1 and is located mainly on the hair and to a lesser extent in saliva. Unlike mites, cat allergens are associated with very small particles of 2.5 μm or less in diameter. Being very light, the particles remain suspended in the air in very high quantities for a long time and when they fall, they accumulate on the upholstery, curtains, carpets and rugs, where they remain for a long time even after the animal has been removed. In environments in which animals lived, it takes at least six months from their removal to bring the concentration levels back to the values ​​of those in which the animal is not present.

Allergens can be transported by means of clothes and can also be found in environments where animals have never been present.

Health effects

The presence of cat allergens can cause sensitization of non-sensitized subjects and above all, induce or aggravate the symptomatology (rhinoconjunctivitis and asthmatic attacks) in allergic subjects.

The problems of allergic origin caused by dander, hair and saliva of dogs seem to be less common in Italy than those caused by cats, but doubts exist in this regard.
