Abstract

Objective To demonstrate molecular characterization of a newly isolated enterovirus.Methods Virus were isolated from patient with unknown-causing disease and tested by reverse transcription-polymerase chain reaction (RT-PCR) and 5' ,3'RACE (rapid amplification of eDNA ends, RACE), in an attempt to obtain the sequence of this newly isolated enterovirus. Results Sequence analysis showed that this newly isolated enterovirus shared 83 %-94% nucleotide identity and 91%-100% amino acid identity with enterovirus 89.Phylogenetic analysis indicated that it was probably a new subtype of enterovirus 89. Conclusion This newly isolated enterovirus in the stool specimen from patient has the same serotype with enterovirus 89, but it was probably a new subtype of enterovirus 89. Key words: Enterovirus; Genome; Genes, structural, viral
