Leukemia developed at a slower rate in A/J mice inoculated with 5 FFU of FV. A very small dose (0.5 FFU) of the same virus caused slow development of leukemia that later regressed in most A/J mice (73%). In (A/J X C57BL/6J) F 1 and their reciprocal hybrids, leukemia developed rapidly after the injection of 500 FFU, but regressed in 97% of the mice. © 1973, SAGE Publications.
