Abstract: | The occurrence of fungal spores in the upper respiratory tract and in the homes of 86 patients with allergic manifestations
and positive skin tests for fungi has been investigated.Alternaria tenuis andCladosporium herbarum have been more frequently found to give positive reactions, followed byAspergillus mix,Candida albicans andPenicillium notatum. Cladosporium andAlternaria represented also the most common moulds isolated from nasal specimens. The prevalent fungi isolated from patients' environments
wereCladosporium, Penicillium andAlternaria, occurring respectively in 93%, 78% and 72% of the homes sampled. An examination of individual cases have revealed a surprisingly
close correlation, in 47 out of 86 patients, between positive skin test response and presence in high amount of the same fungi
in patient's respiratory tract and home. In the majority of cases the fungi involved wereAlternaria and/orCladosporium. |
