Outbred N:Gp (NIH General-purpose) Swiss mice, established at the National Institutes of Health, Bethesda, Maryland, USA in 1935. In 1966 two strains (HSFS/N and HSFR/N) were selected for sensitivity and resistance, respectively, to the action of Histamine after treatment with Bordetella pertussis vaccination. In the early 1970’s, a group of mice at the eighth inbred generation of HSFS/N were found to carry the Fv-1b, allele for sensitivity to the B strain of Friend leukaemia virus. Homozygous mice were then inbred as strain FVB, without further selection for histamine sensitivity (Taketo et al, 1991).
