Detailed genetic analysis was carried out of the VP4/VP2 coding region in human rhinovirus species C (HRV-C) strains detected in patients with acute respiratory infection in Japan. Phylogenetic trees were constructed by the neighbour-joining (NJ) and maximum-likelihood (ML) methods. The NJ phylogenetic tree assigned 11 genotypes to the present strains, whilst the ML tree showed that the strains diversified sometime in the early 1870 s.

Recent studies suggest that human rhinovirus species A, B and C (HRV-ABCs) may be associated with both the common cold and severe acute respiratory illnesses (ARIs) such as bronchiolitis, wheezy bronchiolitis and pneumonia. However, the state and molecular epidemiology of these viruses in Japan is not fully understood. This study detected the genomes of HRV-ABCs from Japanese patients (92 cases, 0-36 years old, mean±sd 3.

Background: Recent studies strongly suggest that some respiratory viruses are associated with the induction of acute wheezing and/or exacerbation of bronchial asthma. However, molecular epidemiology of these viruses is not exactly known.

Methods: Using PCR technology, we attempted to detect various respiratory viruses from 115 Japanese children.
