Establishment of a salmonella-free Guinea pig colony.
Salmonellosis due to Salmonella typhimurium was enzootic in a guinea pig breeding colony for over 25 years. A Salmonella-free auxiliary colony was established by removing weanlings from the infected colony to a clean area, and preventing infection. Examination of agglutinin titers and necropsy specimens indicated that the auxiliary colony was still free from Salmonella 18 months after its establishment while 24% of the guinea pigs dying in the infected colony yielded Salmonella typhimurium.
