In Thailand, the outbreak of H5N1 virus was formally reported since January 2004

• Before 2004, Thailand has been the world’s major poultry exporters (~ 1 billion chickens / year)

• After the spread of H5N1 avian influenza virus in Thailand, more than 100 million birds were killed

There are several variation patterns of inserted basic amino acid

20 amino acids deletion within the stalk region of 20 amino acids deletion within the stalk region of Neuraminidase proteinNeuraminidase protein

All of the viruses isolated from Thailand have 20 aa deletion within the stalk region of NA (may increase retention of virions at the plasma membrane)

Oseltamivir sensitive / resistance in NA Oseltamivir sensitive / resistance in NA at amino acid position 274at amino acid position 274

• Mutation of H274Y Oseltamivir resistance• Fortunately, all of the isolates in Thailand were sensitive to Oseltamivir

Amantadine sensitive / resistance in M2Amantadine sensitive / resistance in M226 3126 31

Dual amantadine resistance mutations at positions 26 and 31 were found in

most of H5N1 influenza isolated in Thailand

• Viruses isolated from avian species contain 627E (Glu)• Viruses isolated from mammalian species contain 627K (Lys)

5 amino acids deletion and C-terminal of NS5 amino acids deletion and C-terminal of NS9292

• 5 amino acid deletion (80- 84): may enhance the virulence• D92E resistance to IFN and TNF-alpha treatment• Carboxyl-terminus (ESEV): may correlate with virulence in mammals

Conclusions

• Bioinformatics are crucial for molecular epidemiology of H5N1 avian influenza– Phylogenetic analysis– Genetic characterizations

• LPAI or HPAI• Anti-viral drugs resistance mutant • Virulence of the virus
