The development of an in situ hybridization assay provides a potential method for the unequivocal diagnosis of enteroviral heart disease and for studying its pathogenicity.
Supports myocardial enteroviral RNA detection in animal models; leaves open validation for human enteroviral heart disease diagnosis.
We have developed an in situ hybridization assay capable of detecting enteroviral RNA in myocardial cells, using molecularly cloned coxsackievirus B3 cDNA as a diagnostic probe. Because of the high degree of nucleic acid sequence homology among the numerous enteroviral serotypes, including the group A and B coxsackieviruses and the echoviruses, detection of these various agents commonly implicated in human viral heart disease is possible in a single hybridization assay. We demonstrate the considerable potential of this method for an unequivocal diagnosis of enteroviral heart disease as well as for pathogenicity studies. Using athymic mice persistently infected with coxsackievirus B3 as a model system, we show that the myocardium is affected in a disseminated, multifocal manner.
