چکیده مقاله:
Backgrounds and Aims: Coxsakievirus B۳ (CVB۳), one of the six Coxsakievirus B serotypes, is a member of the Enterovirus genus within the Picornaviridae family. CVB۳ is an important pathogen of viral myocarditis, which accounts for more than ۵۰% of viral myocarditis cases. The genome of CVB۳, like that of other Entroviruses, is a single-stranded, sense, polyadenylated RNA molecule with ۷۴۰۰ nucleotides in length and a single open reading frame (ORF), flanked by ۵΄ and ۳΄ non-translated regions. The capsids of coxcakieviruses are composed of the four structural proteins: viral protein-۱ (VP۱), VP۲, VP۳, and VP۴. In the present study, a new set of primers were designed based on the VP۱ for RT-PCR detection of CVB۳.
Materials and Methods: Total RNA was extracted from CVB۳-infected HeLa cell line and cDNA was synthesized using random primers. Then, PCR was carried out by specific primers and the PCR product analysis was performed using ۱% agarose gel electrophoresis. Moreover, the sensitivity and specificity of this method were determined using serial dilution of CVB۳ cDNA and three genuses of entroviruses, respectively.
Results: RT-PCR assay revealed a ۲۳۴ bp specific amplified fragment. The sensitivity of this test was determined ۵.۷۲ fg/µl cDNA. On the other hand, the specificity was successful in comparison with coxsackievirus A۱۶, Echovirus ۳۶ and Rhinovirus.
Conclusions: The RT-PCR is a highly sensitive and rapid technique for detecting CVB۳ infection. Moreover, this method can be used as an easy diagnostic test in regard with CVB۳ detection in the clinical laboratories.
