The Austrian section of the Danube was sampled monthly in order to determine several sanitary microbiological parameters such as plate count, total and faecal coliforms, faecal streptococci and Salmonella sp., and these parameters were compared with bacterial abundance, bacterial production and extracellular enzymatic activity. The sanitary bacteriological parameters showed similar spatial variations along the main river. A marked increase was observed downstream of the City of Vienna. Only glucuronidase activity followed the same pattern as the plate counts. A highly significant correlation was found between glucuronidase activity and faecal coliform counts. The glucuronidase-MUF technique seems to be superior over traditional techniques if samples are taken frequently. The sampling sites on the right bank upstream of Vienna were classified as moderately polluted and the stations downstream were moderately to strongly polluted with faecal material, according to the classification of Kohl (1975).
