Swiss Webster (CFW) Mouse

This stock resulted from the selective inbreeding by Dr. Leslie Webster using foundation animals from a large colony of Swiss mice maintained at Rockefeller Institute following importation from Switzerland in 1926. To Carworth Farms from Rockefeller Institute. Highly inbred at the time they were acquired by Carworth. This line was reduced to a single pair and progeny outbred from that point forward to form a new stock. To Charles River in 1974 from a representative cross section of the Carworth CFW colony.
