Skin Prick test was applied to 108 patients with allergic rhinitis from the Hospital
Vasco of Quiroga, ISSSTE, placed in Morelia, Michoacan. For the isolation of strains on PDA,
nasal and pharyngeal swabs were obtained from patients had a positive skin prick test for allergenic fungi
being the specimens identified by morphological methods and using a
biotypification system (Biolog). The frequencies of positive skin Prick test to allergic fungi
genera were the following: Candida 65.7%, Aspergillus 15.7%, Cladosporium 13.89%,
Alternaria 10.2%, Rhizopus 9.3%, Helminthosporium 6.5%, Penicillium 5.6% and Mucor
4.6%. Statistical correlation between the results of the different methods was not significant
(P> 0,05), due to several fungal genera identified did not induce detectable hypersensitivity
reactions in the subcutaneous test, and the allergenicity of some fungi detected by Biolog
system is not known. It is required to continue studying the relation between apparently non
allergenic fungi with the atopic host and his pathogenic microbiota.
