USES FOR LONG POLAR FIMBRIAE GENES OF PATHOGENIC ESCHERICHIA COLI STRAINS

摘要

Provided are methods for identifying lpf genes in pathogenic serotypes of the Enterobacteriaceae family and for differentiating Escherichia coli (E. coli) O157:H7 strains in an isolate using primer pairs specific to lpf gene variants, particularly IpfA1 and/ or lpfA 2 genes and amplicon size of the PCR product to identify prototypic Enterobacteriaceae serotypes or more specifically, to differentiate strains of E. coli serotype O157:1-17. Differentiation further requires identifying the E. coli isolate's eae gene variant type which in combination with the IpfA1 and/or lpfA2 variant identification provides unique markers. Also provided are the primer pairs and a kit comprising the same.
