We compared the detection of seven respiratory viruses by using a commercially available monoclonal antibody pool in a 2-day shell vial assay with that by using standard cell culture with respiratory syncytial virus (RSV) enzyme-linked immunosorbent assay (ELISA)-negative nasal secretions from hospitalized children. We found 179 respiratory virus isolates by either method in 675 specimens. Overall, the shell vial assay detected 147 of 179 (79%) of the positives after 2 days; cell culture detected 148 of 179 (80%) after a mean incubation period of 7.6 days (range, 1 to 14 days). The sensitivity of the shell vial assay was 78% for RSV, 94% for influenza B virus, 83% for adenovirus, and 80% for parainfluenza viruses. The sensitivity of the cell culture was 70% for RSV, 79% for influenza B virus, 90% for adenovirus, and 89% for parainfluenza viruses. The 2-day shell vial assay allowed the detection of respiratory viruses in a clinically relevant time frame and rapidly detected RSV in specimens lacking RSV antigen by ELISA. |
