Development of A Multiplex PCR Method for Detecting Six Types of Viruses Causing Encephalitis / 现代检验医学杂志

ABSTRACT

Objective To develop a new mPCR method for rapid diagnosis of six types of encephalitis causing viruses of HS-VI,HSVII,VZV,EBV,EV71 and CMV.Methods Six pairs of specific primers for CMV,EV71,HSV I,VZV,EBV and HSV II were designed.The mPCR detection method was established and the sensitivity was detected.In order to verify the clinical application value of their multiplex PCR system,fifteen cerebrospinal fluid specimens of clinically suspected VE from the First Affiliated Hospital of Soochow University from 2014 to 2015 were examined by the mPCR method.Results The 6 pairs of primers did not interfere with each other,and the sensitivity of the mPCR system was over 103copies/μl.Among 15 cerebrospinal fluid specimens from patients with suspected viral encephalitis,six specimens(6/15,40%)were tested positive by the mPCR.Among them,HSV I was 5 and CMV was 1.Conclusion The mPCR method for detecting six types of en-cephalitis-associated virus at same time was established with high specificity,sensitivity and stability.
