A Novel Neuraminidase Deletion Mutation Conferring Resistance to Oseltamivir in Clinical Influenza A/H3N2 Virus
1 Dec 2008
Abstract excerpt
Neuraminidase (NA) mutations responsible for influenza resistance to oseltamivir vary according to the NA subtype; in influenza A/H3N2 viruses, NA-gene mutations occur predominantly at codons E119 and R292. In an oseltamivir-resistant influenza A/H3N2 virus isolated from an immunocompromised child after 107 days of cumulative treatment, the NA gene contained 3 aa substitutions (N146K, S219T, and A272V) and a 4-aa...
