Polymorphic loci that differentiate escherichia coli 0157:H7 from other strains

摘要

The present invention relates generally to the field of microbiology and food sciences. More particularly, the inventor has discovered several polynucleotide sequences encoding the gnd gene and corresponding 6-phosphogluconate dehydrogenase (6-PGD) proteins from different strains of Escherichia Coli and polymorphic sequences therein. Novel biotechnological tools, diagnostics, and food screening techniques are provided.
