a
Viremia titer expressed as log10 of PFU/mL serum. Min = minimum, Max = maximum.
b
Plaque reduction neutralization assay against SLEV with an 80% endpoint (PRNT80) criterion. DPI = day postinoculation, N = negative, nd† = no data available, individual died before sample collection. Inf = infected, NInf = not infected, UNK = insufficient data. StDev = standard deviation.
c
na = not applicable; neither mean nor standard deviation calculated due to lack of data.
Group A: Naïve House sparrows inoculated with 79V-2533 SLEV strain (non-epidemic), Group B: Naïve House sparrows inoculated with CbaAr-4005 SLEV strain (epidemic) and Group C: Anti-flavivirus antibody positive House sparrows inoculated with epidemic SLEV strain.
