BALB/c Mouse


Halsey J Bagg at Memorial Hospital obtained and began breeding the strain after obtaining mice from an uncertain dealer in Ohio in 1913. From 1913-1922 the animals were bred by Little and MacDowell at the Carnegie Institution of Washington. Then in 1932, the animals were raised by Snell. Snell donated breeders to Adervont at NIH. Hilltop obtained breeders from NIH and began breeding the colony beginning in 1951. All colony histories contain some possibility of inaccuracy. This information is provided to the best of Hilltop's knowledge.

The coat color of the mouse is albino. The mouse is propagated by brother x sister mating. The colony at Hilltop is a closed colony and has been so since 1999. Closed colonies develop qualities causing the rats to be uniquely suited to certain types of research.
