Inbred Strains of Mice: PBA


Inbr: F20 +. Albino. Genet: c. Origin: P. C. Bailey from a pair of pet shop mice purchased in Birmingham, Alabama, in 1958.


Litter size 6.1; 6 week weight 21 g (both sexes); mean life-span 317 days in males, 268 days in females. Spontaneous lymphomas 100%, mammary tumours 74%, pulmonary adenomas 77% in animals over 1 year (Bailey et al., 1970., 1970). Development of spontaneous adenomas associated with increased serum concentration of IgG1 and IgG2 immunoglobulins (Schrohenloher and Bailey, 1972).
