[Fungi inside and outside the homes of subjects with immediate hypersensitivity in Zaragosa (Spain)].
In the study of patients with hypersensitivity to atmospheric fungi, the determination of species distribution in the personal environment of the patient is important. This distribution depends on climate variations, especially temperature and percent (%) humidity which favor the development of one or other genera. In the domiciliary surroundings, the technological advances in comfort (wetness, dryness, with refrigeration and heating systems) favor the establishment of a closed ecosystem which can sometimes contain fungi different from that found exteriorly; at times true colonization. Our objective is to compare the incidence of the different groups of intra and extra-domiciliary fungi in our environment (Zaragoza, Spain) and to verify their presence in the domiciles with their exterior surroundings, of 23 atopic patients, of which 8 had clinical asthma and/or rhinitis and demonstrable allergy to fungi, by PRICK and RAST. The other 15 patients were diagnosed as having asthma and/or rhinitis with a positive PRICK and RAST to house dust and Dermatophagoides or pollen allergens (non-allergic to fungi). Five Petri dishes were given to each patient; one dish contained 5 mm. of Agar-Sabourad following Lumpkins' formula, and was used for extra-domiciliary exposure. The rest contained the same medium to which was added a 0.33% solution of Rose Bengal (an inhibitor) for internal exposure. This medium allows the development of a large number of genera of fungi. These 5 dishes were situated and remained in place for 60 minutes; the 4 interior ones were placed in different locations and always included the dormitory and living room.(ABSTRACT TRUNCATED AT 250 WORDS)
