MORPHOLOGICAL-CHARACTERISTICS OF ASPERGILLUS-FUMIGATUS STRAINS ISOLATED FROM PATIENT SAMPLES

The Aspergillus fumigatus group splits into the anamorphic A. fumigatu s series and the teleomorphic Neosartorya fischeri series. The species A. fumigatus Fresenius is the most common species within the ii. fumi gatus series. Forty-seven clinical isolates out of the A. fumigatus gr oup were obtained from patients with diseases such as localized and in vasive aspergilloses or allergic disorders due to Aspergillus and were mainly isolated from respiratory secretions. Isolates were studied co ncerning macro-and micromorphological parameters. All isolates were sh own to be isolates of the species A. fumigatus Fresenius. In general, the macro-and micromorphological variability between the different iso lates was low, Four isolates (DSM 10661, DSM 10662, DSM 10705, DSM 110 69) showed significant differences towards the type strain A. fumigatu s Fresenius ATCC 1022; one Of these isolates was highly atypical (DSM 10705).
