Abstract

In the period 1992-95 there was a significant shift in the spectrum of Candida species in the University Hospital in Greifswald. During this time, the annual number of specimens taken for mycological investigations of adults increased threefold (total n = 11,568). The isolation rate of Candida species was 50.5%. The percentage of C. albicans isolates decreased from 76% to 54.4% with the lowest level in 1994. The opposite trend in the occurrence of non-C. albicans species was seen, for example the occurrence of C. glabrata, from 11.7% to 28.4%. We found only 98 strains of C. parapsilosis (1.4%) during the 4 years. The occurrence of Candida species in a variety of habitats was different. During the 4 years, the same annual percentages of C. albicans (mean 87.9%) were isolated from endoscopic oesophageal smears, whereas the distribution of Candida yeasts from the oral cavity, the respiratory tract, faeces and urine had changed. Over the years, at these locations, C. albicans was less frequently isolated and non-C. albicans species clearly increased. The highest occurrence of C. glabrata was found in urine, in which the isolation percentage almost doubled from 23.1% to 40.9% in 1994. In contrast to adults, in all specimens originating from a paediatric clinic that included neonatology the occurrence of C. albicans was high (83.5% in 1995), but the isolation rate of Candida species was low (12.3%). These results are important because of the differences in yeast susceptibility, of non-C. albicans species in particular, against antifungal drugs.
