Objective:Todetectandquantitategenitalherpessimplexvirus(HSV)DNAinspecimensfrom100patientsclinicallydiagnosedwithgenitalherpes.Methods:PolymeraseChainReaction(PCR)andenzyme-linkedimmunosorbentassay(ELISA)wereusedwithastandardcurveofDNAcopiesofHSVasquantitativecontrast.Results:Ninety-threecaseswereconfirmedHSVpositiveand7caseswerefoundtobenegative.Therewere58casesofHSV-2(62.4%)and35casesofHSV-1(37.6%)amongthe93positivecases.ThenumberofDNAplasmidsrangedfrom115to1.1×l0^5per250pLamongthe93positivesamples(mean=7.1×10^4/250μL).ThenumberofHSVDNAplasmidsrangedfrom136to1.1×l0^5copiesper250pL(mean=7.6×10^4)amongthosewithHSV-2,and115to9.4×10^4per250pL(mean=6.3×10^4)amongthosewithHSV-1.Meanwhile10μLofextractedanddissolvedDNArandomlytakenfrom8eachofHSV-2andHSV-1samplesweretested.ThenumberofHSV-2DNAplasmidsrangedfrom35copiesto2.7×10^4(Mean=l.8×10^4)andthenumberofHSV-1DNArangedfrom29to2.5×10^4(Mean=1.6×10^4).Inthe7negativecases,thequantityofHSVplasmidswaszero.Conclusion:ThesensitivityofELISAquantitation(93%)isequaltothatofSouthernblot.ThesensitivityofPCRfordiagnosisis91%,and88%forPCRtyping.
