[Genome analysis of a newly isolated enterovirus].

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 cDNA 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.
