Escherichia Coli
New Escherichia coli research has been reported by C. Laing et al
December 9th, 2008
"In this study, variably absent or present (VAP) regions discovered through comparative genomics experiments were targeted for the development of a rapid, PCR-based method to subtype and fingerprint Escherichia coli O157:H7. Forty-four VAP loci were analyzed for discriminatory power among 79 E. coli O157: H7 strains of 13 phage types (PT)," scientists in Lethbridge, Canada report. "Twenty-three loci were found to maximize resolution among strains, generating 54 separate fingerprints, each of which contained strains of unique PT. Strains from the three previously identified major E. coli O157: H7 lineages, LSPA6-LI, LSPA6-LI/II, and LSPA6-LII, formed distinct branches on...
