Detection of Low Pathogenicity Influenza A(H7N3) Virus during Duck Mortality Event, Cambodia, 2017
|Gene segment and risk factor
||Amino acid change
||Isolates in Cambodia
|Mammalian host range marker and increased viral pathogenicity
|Multibasic cleavage site causing increased pathogenicity||Multibasic||PEPPKGR/GLF||Monobasic||(10)|
|Increased mammalian receptor specificity
|Resistance to NA inhibitor antivirals
||H275Y§||H||Sensitive to oseltamivir
|Resistance to M2 inhibitor antivirals||L26F||Q||Sensitive to M2 inhibitors||(13)|
*HA, hemagglutinin; MP, matrix protein; MP2, matrix protein 2; NA, neuraminidase; PB2, polymerase basic protein 2.
†Receptor binding specificity and antiviral sensitivity is predicted based on sequence information and has not been experimentally confirmed.
