Neuraminidase inhibitor-resistant and -sensitive influenza B viruses isolated from an untreated human patient

Antimicrob Agents Chemother. 2006 May;50(5):1872-4. doi: 10.1128/AAC.50.5.1872-1874.2006.

Abstract

An influenza B virus from an infant with no history of treatment or contact with neuraminidase inhibitors demonstrated a significant reduction in sensitivity to these drugs. Here, we describe the analysis of a mixed viral population that contained a novel D197E amino acid substitution that was responsible for this reduction.
