Table 1
Estimated mean nucleotide and amino acid identities of 170 unique respiratory syncytial virus fusion gene sequences*
| Sequence | Mean nucleotide identity, % ± SD | Mean amino acid identity, % ± SD |
|---|---|---|
| Overall, n = 170 | 89.59 ± 8.38 | 95.99 ± 3.25 |
| RSV-A (within group), n = 105 | 97.06 ± 1.33 | 98.85 ± 0.76 |
| RSV-B (within group), n = 65 | 98.65 ± 0.69 | 99.48 ± 0.28 |
| RSV-A vs. RSV-B (between groups), n = 170 | 80.85 ± 0.66 | 92.64 ± 0.56 |
*Mean nucleotide and amino acid identities were estimated by calculating pairwise distances in MEGA5 software (www.megasoftware.net) and using the maximum-composite likelihood and Poisson correction models, respectively. RSV, respiratory syncytial virus.
