Murine resistance to street rabies virus: genetic analysis by testing second-backcross progeny and verification of allelic resistance genes in SJL/J and CBA/J mice.

摘要

Intraperitoneal challenge with street rabies virus of second-backcross offspring produced from susceptible females mated with either randomly selected or rabies-resistant first-backcross males indicated that murine resistance is under the influence of the concurrent presence of each of two segregating genes. Furthermore, the greater than or equal to 96% resistance of offspring produced from (SJL X CBA)F1 and (CBA X SJL)F1 hybrids crossed to susceptible A.SW or A/WySn mice demonstrated that resistance genes of SJL/J and CBA/J mice are allelic.
