Data
from three independent experiments are shown in Table 2.
More than 90% of the viral plaques from brains of animals
inoculated with rLm-np118 and subsequently infected with
RA59-gfp/gp33 expressing virus were fluorescent and thus retained
the ability to express EGFP activity. On the other hand,
only 15% of the plaques from the brains of mice that were
protected by inoculation by rLm-gp33 were fluorescent. Lysates
from the brains of animals infected with RA59-gfp contained
similar percentages of EGFP expressing plaques
whether or not they had been inoculated with rLm expressing
gp33
