[The pork-cat syndrome or crossed allergy between pork meat and cat epithelia (2)].

Is there a port-cat syndrome in food allergy? Many clinical observations have revealed a frequent association between allergy to cat epithelia in subjects who have allergy to pork meat. This second part, from clinical tests such as skin tests and laboratory tests such as CAP RAST, electrophoresis, Western blot and chromatography, confirms the existence of a crossed reaction between pork meat and cat extract. This crossed reaction is linked with a common epitope. A common protein has been found that has a molecular weight of 67,000 d. for subjects who are sensitive to cat extracts and pork meat.
