Περίληψη:
The counts of yeasts and filamentous fungi were investigated in the
municipal water supplies of haemodialysis centres, in the treated water
and the dialysate from all 85 haemodialysis units in Greece, in order to
estimate their occurrence, their correlation with contamination
indicator bacteria and other influencing factors. Filamentous fungi and
yeasts were isolated from 69 (81.2%) and from three (3.5%) feed
it;ater samples, from 74 (87.1%) and seven (8.2%) treated water
samples and from 66 (77.7%) and 11 (12.9%) dialysate samples
respectively Aspergillus spp and Penicillium spp were the most frequent
moulds, while Candida spp were the prevailing yeasts. The occurrence of
yeasts was significantly higher in dialysate than in tap water samples.
Counts of filamentous fungi in all 255 samples were significantly
correlated with the counts of total heterotrophic bacteria and
enterococci, whereas the counts of yeasts were correlated with faecal
coliforms, total heterotrophic bacteria, as well as enterococci,
Pseudomonas spp and total coliforms, while no correlation was detected
with the age of either heamodialysis units, the age of water treatment
system, the number of artificial kidney machines or the components of
the water purification sq stem. High recovery of fungi from
haemodialysis aqueous environments implies a potential risk for
haemodialysis patients and indicates the need for continuous maintenance
and monitoring. (C) 2000 The Hospital Infection Society.
