Abstract Background Measuring virus attachment to host cells is of great importance when trying to identify novel receptors. The presence of a usable receptor is a major determinant of viral host range and cell tropism. Furthermore identification of appropriate receptors is central for the understanding of viral pathogenesis and gives possibilities to develop antiviral drugs. Attachment is presently measured using radiolabeled and subsequently gradient purified viruses. Traditional methods are expensive and time-consuming and not all viruses are stable during a purification procedure hence there is room for improvement. Real-time PCR RT-PCR has become the standard method to detect and quantify virus infections including enteroviruses in clinical samples. For instance primers directed to the highly conserved 5 untranslated region 5 UTR of the enterovirus genome enable detection of a wide spectrum of enteroviruses. Here we evaluate the
