Table 1. Summary of gene lineage and gene type diversity by segment for the 109 Atlantic flyway duck AIVs from 2006–2011.
Categorya | HA | NA | PB2 | PB1 | PA | NP | M | NS | Total |
Gene lineages | 12 | 9 | 2 | 1 | 2 | 3 | 2 | 3 | 34 |
Gene sub-lineages | 19 | 20 | 6 | 8 | 7 | 9 | 3 | 4 | 76 |
Gene types | 38 | 38 | 29 | 31 | 34 | 32 | 23 | 23 | 248 |
Gene types identified in species other than ducks | 14 | 14 | 14 | 18 | 22 | 19 | 22 | 18 | 141 |
Gene lineages, sub-lineages and types are defined as sharing ≥90%, ≥95% and ≥99% nucleotide identity, respectively.
