DNA Profiling Of E. coli On Fast Track Using New Technique

Using new genetic techniques, scientists are unlocking the secrets of how E coli bacteria contaminate food and make people sick.Michigan State University has developed a new technique to test the DNA of E. coli bacteria by examining very small genetic changes called single nucleotide polymorphisms or SNPs (pronounced snips). Using SNPs, scientists analyzed 96 markers, making genetic analysis of pathogenic bacteria possible at a rate never before accomplished.
