of Mice: BRVR
Inbr: F83+. Albino. Genet: c. Origin: Webster (1933a,b) developed two lines
resistant and susceptible to infection by Bacillus enteritidis
sp.) by selection on the basis of a progeny test, followed by full-sib
mating. Mortality under specified test conditions was 15% and 85%, respectively,
and was about 39% in the unselected controls. Later tests (Webster,
) with louping ill and St Louis encephalitis viruses led to the
development of three lines designated BSVS (bacteria-susceptible, virus-susceptible),
BSVR (bacteria-susceptible, virus-resistant) and BRVS (bacteria-resistant,
virus-susceptible). Later BRVR (bacteria-resistant, virus-resistant) mice
were developed from a cross between BSVR and BRVS, with subsequent selection
for resistance to the two agents, and full-sib mating. There may have
been some confusion between the lines in the past, and authenticity should
not always be assumed.
Hydronephrosis in 11% of females and 18% of males (1/13) (Taylor and Fraser, 1973
), 34-42% in males and 30-34% in
females (Collins et al., 1971
Resistant to Salmonella,
some encephalitic viruses and experimental
allergic encephalomyelitis (Staats, 1976
to experimental allergic encephalomyelitis (cf. 6/14) (Levine and Sowinski, 1973
). Resistant to induction of experimental
autoimmune thyroiditis (cf. 2/5) (Vladutiu and Rose, 1971a). Carries gene
for resistance to group B arbovirus infection (cf. strain PRI) (Darnell et al., 1974
., 1974). Differences between the responses
of BRVR and BSVS to infections and various antigens are listed by Boehme(1970
