Abstract

The SMXA recombinant inbred mouse strain set was produced by systematic inbreeding from the F2 generation of a cross between two progenitor inbred strains, A/J and SM/J, which differed markedly with respect to the patterns of infection with Angiostrongylus costaricensis. We have applied this set to genetic analysis of mouse susceptibility to this nematode infection. The mortality was variable among substrains of the SMXA RI strains, indicating the involvement of multiple genes. Linkage analysis showed several chromosomal regions closely linked to mortality; chromosome 6 (D6Rik86, 87; P<==0.001), 10 (D10Rik66-D10Mit12; P=0.0058), 13 (D13Rik79, 80; P=0.0096) and 17 (D17Mit28-D17Rik76; P=0.0088).
