| amantadine- and oseltamivir-resistant variants of influenza a viruses in thailand. | amantadine and oseltamivir are used to treat influenza a virus infections; however, resistance to these drugs has been widely reported throughout the world. in this study, the frequency and genetic characteristics of the drug-resistant influenza a viruses that circulated in thailand from 2006 to 2008 were investigated. the nucleotide sequences of the na and m2 genes were elucidated in order to identify mutations that confer oseltamivir- and amantadine-resistant phenotypes, respectively. a total ... | 2009 | 19850010 |
