Abstract

Understanding the pathogenesis of viral myocarditis is linked to the availability of sensitive assays to detect viruses in clinical material. Recent advances in molecular techniques permit direct detection of viral-specific nucleic acid in tissue samples. This report describes a protocol for DNA extraction and amplification of adenovirus genome from formalin-fixed, paraffin-embedded human tissues that detects as little as 10 copies of viral genome in a background of 0.5 μg of human DNA. This sensitive assay permitted the examination of archived tissues to establish a retrospective diagnosis of adenoviral myocarditis in two pediatric patients.

    Citation Excerpt :

    Enterovirus infections, such as coxsackieviruses have been considered as the most common etiologic pathogens of viral myocarditis in pediatric population. However, there is evidence that HAdVs may be a significant cause as well [67,68]. Such evidence mainly comes from utilization of PCR assays to detect the presence of nucleic acids in clinical samples.
