Molecular typing of pathogenic microorganisms is important for epidemiological investigation of in-fectious disease outbreaks. In this study, we applied Universal Rice Primers (URP) that were originated from repetitive sequences in rice chromosomal DNA to random amplified polymorphic DNA (RAPD) analysis of pathogenic bacteria such as Escherichia coli, Listeria monocytogenes, and Salmonella sp. Of the twelve URP primers examined to date, seven primers (URP-2, -3, -4, -5, -6, -8, and -9) generated reproducible and polymorphic PCR products ranging from 1 to 13 bands. One of them, URP-6 was very effective in differentiating seven E. coli serotypes, seven L. monocytogenes clinical isolates, and eight Salmonella subspecies (ssp.) serovars. The results thus indicate that RAPD analysis using URP primers might be useful in typing bacterial pathogens including E. coli, L. monocytogenes, and Salmonella strains.
