[The pork-cat syndrome: RAST inhibition test with Feld One].

This work confirms that the common allergen in subjects who are doubly sensitized to cat and pork is quite different from that of subjects who are mono-sensitized to cat. The common protein is Albumin MW 67 Kda in the pork/cat syndrome, while the major allergen Feld One is characteristic in patients who are monosensitized to cat.
