猪瘟病毒巢式 RT-PCR 检测方法的建立与应用
Establishment and Application of Nested RT-PCR Assay for Detection of Classical Swine Fever Virus
摘要
Abstract
A nested RT-PCR for detection of classical swine fever virus (CSFV)was developed u-sing the total RNA of CSFV as a reverse transcription template,and two pairs of specific primers were designed based on the conserved region of CSFV E 2 gene.The specificity,sensitivity and repetition of CSFV nested RT-PCR were tested,and 35 samples taken from clinical suspicious CS-FV infected pigs were tested by the established nested RT-PCR assay.The results indicated that the nested RT-PCR assay was successfully established.The sensitivity and specificity of the nes-ted RT-PCR assay revealed that the minimum detectable virus content limit was 1 TCID50 ,and no products were amplified from the nucleic acid of ST normal cell or other 8 pathogenic viral or bac-terial microorganisms.The repetition test indicated the nested RT-PCR assay showed a good re-peatability.Meanwhile,1 9 positive samples were detected in 35 suspected samples,which was con-sistent with the results tested by sequencing.The study suggested that the established nested RT-PCR assay was specific,sensitive and suitable for early detection of CSFV.关键词
