title: Human rhabdomyosarcoma cells for rapid detection of enteroviruses by shell-vial assay.
abstract: The ability of the RD (rhabdomyosarcoma) and MRC-5 cell-lines to detect enteroviruses in 33 clinical samples (cerebrospinal fluid, stools and throat swabs) was evaluated. The samples had previously tested enterovirus-positive by traditional tube-culture and had been frozen after their initial processing. By traditional tube-culture, 100 and 85 % of samples were positive for enterovirus in RD and MRC-5 cells, respectively. By rapid shell-vial assay, 94 and 45.5 % were positive after 48 h incubation in RD and MRC-5 cells, respectively. RD cells supported growth of all enterovirus serotypes, whereas MRC-5 cells were not able to detect any of the three coxsackieviruses that were found (one coxsackievirus A9 and two coxsackievirus B5). The shell-vial assay with RD cell-lines may be a useful tool for rapid diagnosis of enteroviral infection.
