Abstract
BACKGROUND Human rhinovirus (HRV) is a picornavirus that can cause a variety of respiratory diseases, including the aggravation of chronic respiratory diseases, such as bronchitis, pneumonia, and asthma. Although an increasing number of lower respiratory tract infection cases have been reported with HRV infection in Europe, few such cases have been reported in China. METHODS The complete genomic sequences of HRV-A11 epidemic strains were amplifed and obtained by segmented PCR and sequence, then phylogenetic, nucleotide mutation, recombinant, and comparative analyses of amino acid mutations were performed. RESULTS Phylogenetic analyses showed that the epidemic strains from three rare cases of pneumonia belong to the HRV-A11 subgenotypes. All strains were highly similar to strains from the USA. No obvious homologous recombination signals were observed in epidemic strains. There were 498 nucleotide and 47 amino acid mutations compared to the HRV-A11 prototype strain. Amino acid mutations were observed at the capsid protein region, P1a, RVA2147-2155, and RVA97-114 epitopes of these clinical strains. CONCLUSIONS We reported the first case of HRV-A11-associated lower respiratory tract infection in China. These mutations in the P1a, HRV A-specific CD8, and CD4 T-cell epitopes might provide a reference for virological surveillance and vaccine development.
