    Australian zebra finch susceptibility to infection is dependent on challenge level.

    <p>Infection was determined by viral culture and by antibody development. Mortality and viral shedding are presented as the number of birds and the percent of the total number of birds infected.</p

    Patterns of infection, mortality, shedding and peak viremia in Australian versus Timor Zebra Finches.

    <p>In comparisons of Australian and Timor zebra finches under the same challenge level (10<sup>5</sup> PFU), Timor zebra finches show higher infection rates, mortality, and viral shedding, but these differences are not statistically significant.</p

    Post infection detection of WNV across tissue types.

    <p>By 4 dpi WNV was detected by culture or RT-PCR from tissues obtained from all Australian zebra finches. WNV was not detected at all by day 14. N is the total number tested and each column indicated the number of positive within each tissue type.</p

    Relatively more WNV genome equivalents (GE) were detected by RT-PCR in serum samples from Timor zebra finches than in Australian zebra finches.

    <p>Mean AU of detected GE and standard errors are plotted for Australian zebra finches challenged with 10<sup>5</sup> plaque-forming units (PFU) of WNV (solid line), and for Timor zebra finches challenged with both 10<sup>5</sup> (fine dashed line) and 10<sup>3</sup> PFU of virus (dashed line). AU’s of 6–1 represent 1.2 x 10<sup>4</sup>–1.2 x 10<sup>−1</sup> WNV GE/ mL.</p
