a
Results are presented as the number of animals with an SI of ≥2/the total number of animals examinated. In parentheses, the range of values observed is given. Responses to control gp from uninfected MBM cells, in which the viral antigens were produced, were uniformly negative at all times tested.
b
First challenge.
c
Second challenge.
