title: General Transduction in Vibrio cholerae.
abstract: Evidence was obtained for general transduction in Vibrio cholerae. Transduction of three amino acid markers and three antibiotic resistance characters was demonstrated using strains of biotype eltor and biotype cholerae. Some of the genetic characters were transduced from a biotype eltor donor (and its mutant derivatives) to biotype cholerae and eltor recipients. For the genetic traits examined, the frequencies of transduction ranged between 10(-5) and 10(-8). Maximal frequencies were obtained with transducing phage lysates that were irradiated with ultraviolet light. The development of a system of general transduction will now aid in fine structure analysis and detailed mapping of the chromosome of V. cholerae.
