El Gato Siberiano...hypoalergénico?


En primer lugar es importante destacar el hecho de que hasta la fecha no existen estudios oficiales sobre esta propiedad que normalmente se les atribuye a los siberianos. Aun asi, gran número de criadores no estan teniendo ningun problema con personas que en otras circunstancias no podrian tener un gato como mascota. Tambien es importante acentuar el hecho de que hypoalergénico significa menores niveles de alergenos, lo que no quiere decir ninguno. Finalmente, todo depende en gran medida, del tipo de alergia de cada persona. Sobre este tema, solamente se han realizado unos pocos tests, que entre otras razones, debido a la considerablemente pequeña cantidad de muestras utilizadas, no se puede considerar como un estudio general dentro del cual incluir a toda la raza de Gatos Siberianos.

Al final de esta página se puede encontrar el original en Inglés de las conclusiones de INDOOR Biotechnologies, respecto a unas muestras de distintas razas. Si bien los niveles en Siberianos son relativamente reducidos (200µg/g en hembras estirilizadas hasta 2000µg/g en machos esterilizados) indican de todos modos que los gatos Siberianos si producen cierta cantidad de alergenos. De nuevo decir, que es importante tener en mente que este estudio solo ofrece datos para unos pocos y concretos ejemplares de la raza Siberiano.

El Test

 

INDOOR Biotechnologies has received several enquiries concerning cat allergen (Fel d 1) levels in Siberian cats and other cat breeds. In September 2000, a cat lover sent the company four samples from different cat breeds to be tested for Fel d 1 through our INDOOR Allergen Analysis Service. These were hair samples collected by the client and the results have been posted on various web-sites as below:

"Recent News - Results for testing of Fel d1 in fur samples"

These tests were performed in Dec 1999, by an independent lab in Virginia
Indoor Biotechnologies, 1216 Harris St, Charlottesville, VA 22903. The
results are as follows:

INDOOR Biotechnologies comments:

First, the Fel d 1 results are in micrograms per gram sample (µg/g, not mg/g, as posted on various websites). The results have been interpreted to indicate that the Siberian and Abyssinian cats have considerably less allergen than mixed breed house cats, and that females have less Fel d1 than males.

This web posting is creating lots of interest, though INDOOR Biotechnologies did not carry out research on the samples and was not responsible for collecting the samples or validating the results. The company would not provide recommendations on pet ownership based on the results provided under these circumstances. The results do not provide convincing scientific data that Siberian cats are "hypoallergenic" and it is unfortunate that they have been widely disseminated on the web and used by breeders of Siberian cats to promote the breed.

The levels of allergen found in the Siberian samples (200 - 2000µg/g) are high and indicate that these cats produce significant amounts of allergen. Part of the confusion is created by the fact that the results of the mixed breed cat are exceptionally high, for reasons that are unclear and were not investigated at the time. The samples used for analysis were disposed of and cannot be re-tested. We do know from previous published studies that Fel d 1 is conserved in big cat species (lions, tigers, leopards etc) so it seems unlikely that the gene is lacking in strains of domestic cats.
