Directors at Charles River Laboratories have recently presented us with the possibility of eradicating Streptobacillus Moniliformis (the bacteria that causes Rat Bite Fever) by cross-fostering to "clean" nursing females. While this theory is currently untested, it has worked for other bacteria in mice and we are willing to try it!

A group of breeders are coming together to form what we are calling the 'Coalition for the Preservation of Fancy Rat Genetics'. We will be buying clean, health tested rat colonies from a laboratory to test cross-fostering, most likely Wistar Han rats. We currently have 5 primary breeders within an hour of each other who will become the different "stations" to try and do this as securely as possible!
There will be more breeders added to act as additional hubs for "clean" lab rats and to house "dirty" lines to ensure no genetics are lost. This is the basis of what we're planning for this project.
Genes that we have available between us and will be attempting to "clean":
Size: Standard and Dwarf
Ears: Standard and Dumbo
Coats: Standard, Hairless, Werewolf/Patchwork, Rex, Velveteen, Silvermane, Harley, Satin 1, Satin 2, and Lux.
Markings: Self, Hooded, Irish, Berkshire, Variegated, Whiteside, Downunder, Merle, Recessive Blaze, and Roan.
Misc. Colors and Varieties: Black, Agouti, Russian Blue, American Blue, UK Mink, US Mink, AUS Mink, Pearl, RED, PED, Siamese (RE, BE and Golden), Marten (RE and BE), Tonkinese, Burmese.
