Nowadays, diagnostic virology laboratories isolate respiratory viruses predominantly in traditional tube and commercial R-mix frozen cell cultures. The traditional tube culture is generally sensitive but a time-consuming procedure. Nevertheless, the commercial R-mix frozen cell (R-mix) culture is faster for virus isolation but not cost-effective. How to establish a method for accurate, rapid and cost-saving isolation of respiratory viruses is important. We retrospectively used 386 virus-positive samples to test detection rates of shell viral (SV) assays with simultaneous culture of MDCK, MK-2 and HEp-2 cells (CoMMH) and the R-mix culture. A total of 55.0% of the strains (213 strains; 95 influenza type A viruses, 49 adenoviruses, 10 respiratory syncytial viruses and 59 other viruses) were detected by the CoMMH SV assay in 4 days, whereas 39.3% of the strains (152 strains; 56 influenza type A viruses, 32 adenoviruses, 9 respiratory syncytial viruses and 55 other viruses) were detected by R-mix in a mean time of 4 days. The CoMMH SV assay may be useful for the acute and rapid detection of respiratory viruses. |
