| Abstract: | BSVS mice are known to be highly susceptible to salmonella infection. We have shown that the bulk of the difference in susceptibility between BSVS and salmonella-resistant A/J mice is the result of a genetic difference at a single locus not closely linked to H-2, Igh-C, or Hbb, and not X-linked. We have backcrossed the A/J allele at this locus into BSVS mice for 8 successive generations and have demonstrated that the salmonella resistance afforded by this allele is not the result of a restoration of the generalized poor T-dependent responsiveness of BSVS mice. The salmonella resistance locus we have examined with these 2 strains is probably the same as the Ity locus described by others. |
