In this study the Random Amplified Polymorphic DNA (RAPD) fingerprinting technique allowed genetic diversity assessment of 25 E. coli isolates of various sources. A highly significant finding from the DNA fingerprinting is the display of a predominant band at a size of 308 bp when arbitrary OPAE-10 primer was used. After sequencing this fragment primer called secD was designed to be used as PCR primer. secD primer pairs was highly specific to detect all isolates including E. coli O157: H7. ER -
