Characteristics

Leukaemia 50% in females and 19% in males (Staats, 1976), 80-90% (Heston, 1968). Life-span intermediate in males (10/22 = 517 days) and short in females (4/22 = 448 days) in conventional conditions (Storer, 1966). High incidence of leukaemia (Albert et al., 1965., 1965). High gross tumour incidence in females (5/22) (Storer, 1966).

High plasma cholinesterase activity (3/22 in females, 5/22 in males) (Angel et al., 1967., 1967). Large brain weight (4/25) (Roderick et al., 1973., 1973). Small spleen/body weight (9/9 to 6/9, depending on age) (Albert et al., 1966., 1966). Large relative thymus weight (2/8 at 14,49 and 90 days) (Albert et al., 1965., 1965). Susceptible to skin ulceration by DMBA (cf. 13/22) (Thomas et al., 1973., 1973). High lymphocyte phytohaemagglutinin response (1/43) (Heiniger et al., 1975., 1975). Erythrocytes have a high agglutinability (cf. 14/25) (Rubinstein et al., 1974., 1974). High degree of genetic distinctiveness (7/27) (Taylor, 1972). Develop antiphospholipid antibody syndrome with reduced litter size following immunisation with beta(2)-glycoprotein (Garcia et al, 1997). Moderate susceptibility to experimental allergic encephalitis with late onset (2/10) and high mortality (4/10) (Lindsey, 1996).
