MuV detection was carried out by nested RT-PCR on 117 cases. The small hydrophobic gene of 33 isolated strains was identified, and sequence analysis revealed that all the isolates belonged to the lineage genotype F with slight nucleotide variation. Furthermore, the virus haemagglutinin–neuraminidase and nucleoprotein antigens exhibited a high degree of nucleotide and amino acid similarity (>99 %) within all isolates, whilst the fusion protein appeared to have certain geographical differences. This study on molecular surveillance will help to monitor the circulation of MuV in China., UL https://www.microbiologyresearch.org/content/journal/jmm/10.1099/jmm.0.021907-0
