BACKGROUND: To establish a molecular detection and typing assay for identification and typing of human enteroviruses (HEV) which is suitable for clinical detection and epidemiologic research. METHODS: Using both primers specific for HEV genus and HEV typing primers and reverse transcription polymerase chain reaction (RT-PCR) the authors detected preliminarily HEV by agarose gel electrophoresis and then identified serotype through nucleotide sequence analysis of RT-PCR amplicons. The monospecific antisera neutralization was applied to validate the typing results. RESULTS: The serotype of 18 suspicious HEV samples was identified: 4 Coxackievirus type A24 (CVA24), 3 CVB3, 1 CVB2, 1 CVA9, 1 CVA15, 1 Echovirus type 3 (E3), 1 E6, 1 E9, 1 E11, 1 E14, 1 E33 and 1 Rhinovirus type 9. The result was validated by monospecitive antisera neutralization. CONCLUSION: This RT-PCR assay for HEV detection and typing may be suitable for clinical detection and epidemic research since this method is sensitive and specific for direct identification and typing of HEV.
