The role of ferrioxamine E in pre-enrichment medium for determining salmonella in environmental samples according to ISO method

摘要

The effect of a siderophoric compound, ferrioxamine E. in the pre-enrichment broth on determining of Salmonella infantis in environmental samples was tested with combination of various pre-enrichment times and enrichment temperatures of 37 and 43 deg C. Ferrioxamine E slightly improved the determination efficiency of this bacterium but the pre-enrichment time could not be reduced below 17 hours. The enrichment temperature of 43 deg C was better than of 37 deg C. The mixing ratios of 1:100 or 1:1 000 for samples and pre-enrichment broth were more successful than the ratio of 1:10 as recommended by ISO.
