title: Attenuated recombinant strains of Vibrio cholerae for oral immunization.
abstract: Two attenuated strains of Vibrio cholerae, CD1 and CD3, have been isolated that have remained stable since 1976. These strains are motile, adhere to and multiply in rabbit intestine, and colonize the gut of infant mice for 6-7 days. Both strains are antigenic and provide protection to challenge in the mouse protection test and in the rabbit ileal loop model. Because of their ability to adhere to and colonize the gut, and since they are antigenic, strains CD1 and CD3 have the potentiality of oral vaccines.
