| Summary: | We describe the characterization of an enterovirus isolate recovered from untreated raw sewage in Ibadan, southwest Nigeria in 2010. The isolate was neutralized by specific antisera and consequently identified as Echovirus 7 (E7). Subsequent molecular characterization showed the isolate to be a mixture of E7 and Coxsackievirus A24 (CV-A24) thereby suggesting the CV-A24 strain to be non-cytopathic effect producing. It is therefore crucial that identities of enterovirus strains determined by neutralization assay be verified by molecular characterization to ensure they do not have any non-cytopathic effect producing strain(s) lurking unnoticed. |
