ABSTRACT
This study was carried out to prove that some molds even not studied in Mexico can be able to incit a positive skin test. We tested 43 adults (15-45 years old), 34 of them suffering respiratory allergy verified by roentgenography and laboratory tests including traditional intradermic allergic test. 9 subjects served as control group. We used manual scarification to Ustilago maydis, Rhodotorula rubra, Puccinia graminis, Cunhigamella sp and Zyncephalastrum sp. Our patients showed a positive skin test in 26, 12, 12, 9 and 6% respectively. This Fisher exact test do not detects significative differences. We conclude this molds can be able to incit an immune reaction IgE mediated and the must be tested in allergic patients from farmer communities.
