Unexpected interfarm transmission dynamics during a highly pathogenic avian influenza epidemic [PDF]

open access: yes, 2016
Next-generation sequencing technology is now being increasingly applied to study the within- and between-host population dynamics of viruses. However, information on avian influenza virus evolution and transmission during a naturally occurring epidemic ...

Structural Constraints on RNA Virus Evolution [PDF]

open access: yesJournal of Virology, 1999
ABSTRACT The recently discovered hepatitis G virus (HGV) or GB virus C (GBV-C) is widely distributed in human populations, and homologues such as HGV/GBV-C CPZ and GBV-A are found in a variety of different primate species.

Comparative susceptibility of mosquito populations in North Queensland, Australia to oral infection with dengue virus. [PDF]

open access: yes, 2014
Dengue is the most prevalent arthropod-borne virus, with at least 40% of the world's population at risk of infection each year. In Australia, dengue is not endemic, but viremic travelers trigger outbreaks involving hundreds of cases.

Evolution of foot-and-mouth disease virus intra-sample sequence diversity during serial transmission in bovine hosts [PDF]

open access: yes, 2013
RNA virus populations within samples are highly heterogeneous, containing a large number of minority sequence variants which can potentially be transmitted to other susceptible hosts. Consequently, consensus genome sequences provide an incomplete picture
