. Origin: G. Bonser (Leeds) 1932-1936 by selection for formation of a
`wart' after tar application.
Now more susceptible than five other strains (including BALB/c and CBA)
to tar, methylcholanthrene and 3,4-benzpyrene. No spontaneous mammary
tumours (Bonser, 1938
). Susceptible to induction
of brain tumours by N
-nitrosourea (Searle and Jones, 1972
). High incidence of spontaneous
pseudopregnancy. Maint. by A.
