  • Title: Resistance and susceptibility of mice to bacterial infection: genetics of listeriosis.
    Author: Cheers C, McKenzie IF.
    Journal: Infect Immun; 1978 Mar; 19(3):755-62. PubMed ID: 305895.
    Abstract:
    A survey of various strains of mice showed distinct differences in resistance or susceptibility to Listeria monocytogenes. C57B1, related sublines, NZB, and SJL were resistant to Listeria, whereas BALB/c, CBA, A, DBA/1, C3H, LP.RIII, 129, and WB were susceptible. The gene(s) responsible for resistance and susceptibility to Listeria were studied in detail. C57BL6/6, B10.D2, and B10.A mice were 100 times more resistant than were BALB/c, CBA, and A. Resistance of the (C57B1/6 X BALB/C)F1 was intermediate between the two parents, suggesting partial penetration of a dominant gene. Backcross studies in which the (C57B1/6 X BALB/c)F1 were crossed with the susceptible BALB/c parent suggested that a single gene or group of linked genes were the major determinant of resistance, although the possibility that other genes exerted a modifying influence was not excluded. By using the backcross and various congenic and recombinant mice, linkage of the genes involved to the H-1, H-2, H-3, H-4, H-7, or H-8 loci, to the immunoglobulin allotype, to the Thy-1 gene, to the Hc gene specifying C5, or to coat color genes (B, c) was excluded. There was no difference in the response of males and females. In all studies, the powerful overriding influence of the C57B1 genome was evident.
