Interaction between loci controlling parasite burden in lymph nodes and liver 43 weeks after infection.

Means, SE and P values for concentration of parasite DNA (ng/µl) in isolates from lymph nodes and liver were computed by analysis of variance. The following transformations were used to obtain normal distribution: natural logarithm of (value×100). Hepatomegaly (liver-to-body weight ratio×1000) was normalized by raising values to the power of 0.0125. The numbers in bold give the average non-transformed values. Only P values significant after correction for genome-wide significance are given. Number of tested mice is shown in brackets. C and S indicate the presence of BALB/c and STS allele, respectively.
