Emergence of an oseltamivir-resistant influenza A/H3N2 virus in an elderly patient receiving a suboptimal dose of antiviral prophylaxis.

ABSTRACT: We report the emergence of an influenza virus A/H3N2-E119V neuraminidase variant from an elderly patient with renal dysfunction who received a suboptimal dose of oseltamivir prophylaxis. In neuraminidase inhibition assays, the E119V variant showed a 413-fold increase in the 50% inhibitory oseltamivir concentration and grew at titers comparable to those of the wild type in vitro.
