A comparative study of antigens of Aspergillus fumigatus isolates from patients and soil of ornamental plants in the immunodiffusion test.
The strikingly frequent and constant presence of Aspergillus fimigatus in the soil of potted ornamental plants kept in private houses and hospitals has been the reason for studying the antigens of the strains found from the diagnostic and epidemiological angles. Culture-filtrate antigens of A. fumigatus strains isolated from the soil of 4 different ornamental plants, epiphyllum (Epiphyllum truncatum), orange tree (Citrus sinensis), Alpine rose (Azalea indica) and Christmas flower (Euphorbia pulcherrima), were compared, in the immunodiffusion test, with antigens of A. fumigatus strains from aspergillosis patients prepared in an identical way. When tested against 8 different sera from different aspergillosis patients there was a good coincidence of results. Control sera from patients suffering from diseases other than aspergillosis, no false-positive reactions could be observed. The findings are discussed in respect of diagnosis and epidemiology.
