Table 4. Gene constellation of different genotypes of new H5N1 influenza viruses in Hong Kong
Genotype | Internal protein gene segments | |||||
PB2 | PB1 | PA | NP | M | NS | |
A | AqA*1 | AqA 1 | Gs/Gd | AqA 1 | Gs/Gd | AqA1 |
B | AqA 1 | AqA 1 | AqA 1 | AqA 1 | AqA 1 | AqA1 |
C | AqA 1 | Gs/Gd | AqA 1 | Gs/Gd | AqA 1 | AqA 1 |
D | AqA 1 | Gs/Gd | AqA 1 | Y280 | AqA 1 | AqA 1 |
E | AqA 1 | Gs/Gd | AqA 1 | AqA 2 | AqA 1 | AqA 1 |
Note: The presumed initial gene source is denoted AqA.
*, denotes aquatic avian genes from two separate sources - AqA 1 and AqA 2. Genes derived from the precursor Gs/Guangdong/1/96-like viruses are denoted Gs/Gd, and that from Dk/HK/Y280/97 is denoted Y280.
