| thermostability of subpopulations of h2n3 influenza virus isolates from mallard ducks. | maintenance of avian influenza virus in waterfowl populations requires that virions remain infectious while in the environment. temperature has been shown to negatively correlate with persistence time, which is the duration for which virions are infectious. however, thermostability can vary between isolates regardless of subtype, and it is not known whether this variation occurs when host and geographic location of isolation are controlled. in this study, we analyzed the thermostabilities of 7 h ... | 2010 | 20610728 |
