- Аннотация: A number of ecophysiological differences were shown for saprotrophic and clinical strains of the potentially pathogenic microscopic fungus Aspergillus sydowii. The colony growth rates were determined for four saprotrophic and five clinical fungus strains on Czapek medium within the ranges of temperature (5, 10, 15, 20, 30, 35, 37, 40, 42°C) and humidity (0.8, 0.85, 0.9, 0.95, 099 aw), as well as on media with other sources of organic matter (Sabouraud medium, Hutchinson medium with cellulose, and water agar). The capacity for growth of A. sydowii strains on a broad spectrum of organic substrates was determined with the EKOLOG method for multisubstrate testing. The clinical and saprotrophic strains of A. sydowii differed in the colony growth rates under the same temperature and humidity combinations, as well as in the capacity for growth on different organic substrates. At decreased water activity (0.90–0.85 aw), the temperature interval for growth of the saprotrophic strains was narrower (30 ± 2°C) than for the clinical strains (25–30°C). Comparison of growth on different media revealed the highest growth rates of the clinical strains on Sabouraud protein-containing medium. The method of multisubstrate testing showed that the saprotrophic strains grew on sugars better than the clinical ones.
