Cultures individually infected with bacGFPVP2 or bacVP6. Both sets of cultures are plotted in the same graphs to allow comparison. A. Fraction of the population expressing GFPVP2, gp64, or VP6 at 24 hours post infection (hpi). The probability (p) of a population of being infected by w virus, predicted by Poisson, is shown as a solid line. B. The same cultures as in A but at 48 hpi. Media and difference between duplicate cultures are shown in Y axis error bars. X error bars represent the standard deviation of titers of the viral stocks, adjusted to each MOI. Some error bars are smaller than the symbols shown.
