Exposición y sensibilización a Tyrophagus putrescentiae en una población de alérgicos a Dermatophagoides pteronyssinus en Huelva

Background In this work we analyzed the allergological importance of Tyrophagus putrescentiae (Tp) in Huelva (SE Spain). We studied the level of exposition and the grade of sensitization to Tp in a group of patients sensitized to Dermatophagoides pteronyssinus (Dpt). The allergenic cross-reactivity between Dpt and Tp was determined by RAST inhibition.
