Tosupportthescientificbasisforrapididentificationofpathogenicbacteriaandotherstud-ies,thesequencesofhsp60geneinmajor34speciesof16genusofpathogenicbacteriaweresearchoutinGenBankandaproperpairofuniversaldegenerateprimerwasdesignedbymeansofthemolecu-larbiologicalsoftwawePrimer5.0andOligo6.0.ThisprimerwasthenusedinthePCRamplification,andthehsp60genefragmentsoftheselectedpathogenicbacteriacouldbeamplifiedusingthisdegener-ateprimer.Bywayofbioinformationalanalysis,theconservation,variationandtheinterspeciesphylo-geneticrelationsofthehsp60genesequencewereanalysed.Fromtheresultsofthecomparativestudyonsequences,itwasdemonstratedthatthehsp60genewascharacterizedbyconservationandvaria-tion,inwhichtheconservedandmutantregionsco-existedandseparatelydistributedwithmanysmallmutantregionsdistributedamongtheconservedregions,justlikethemosaic.Thephylogenetictreeamongdifferentpathogenicbacteriadrawnfromthehsp60geneanalysiswasprovedtobeconsistentwiththosefrom16SrRNAand23SrRNA.Itisconcludedthatthesequencedistributionofhsp60genewouldprovideasolidbasisfortherapididentificationofpathogenicbacteriaandthedevelopmentofadiagnosticmicroarray.
