P/A

Inbr: 91. Origin: P. Kortweg 1934; DBA female x C57BL male, then N20 to C57BL, then b x s inbred.

P/J

Inbr: F153. Pink-eyed fawn. Genet: a, b, d, p, rd, se. Origin: Snell from a cross involving strain BDP. Carries the pink-eyed dilution gene, p, which is derived from Asian mice of the Mus musculus type (see also strains SJL, 129/J and FS/Ei) (Brilliant et al, 1994)

Characteristics

Lymphatic leukaemia 22% in males and 29% in breeding, and 58% in virgin females. Primary lung tumours zero in males and 3% in females (Hoag, 1963). Life-span short (3/22 = 384 days in males and 8/22 = 510 days in females) in conventional conditions (Storer, 1966). Low metabolic rate (15/18) (Storer, 1967). High serum ceruloplasmin levels in females (4/27) (Meier and MacPike, 1968). High susceptibility to audiogenic and electroconvulsive seizures (1/6) (Deckard et al., 1976., 1976). Large brain weight (15/18 in males, 14/18 in females) (Storer, 1967). Large brain/body weight ratio (1/20) and large spinal cord (2/25) (Roderick et al., 1973., 1973). Resistant to X-irradiation (5/27) (Roderick, 1963). Short survival in 90% oxygen (3/10) (Lieberman and Kellog, 1967). Low lymphocyte phytohaemagglutinin response (37/43) (Heiniger et al., 1975., 1975). Intermediate breeding performance (15/24) (Hansen et al., 1973., 1973).

High degree of genetic distinctiveness (8/27) (Taylor, 1972). Susceptible to colon carcinogenesis by 1,2-dimethylhydrazine (cf. 3/7) (Evans et al., 1977., 1977).
