| Abstract: | Sixty-six strains unable to ferment sucrose and resemblingVibrio mimicus andV. cholerae were submitted to an extensive phenotypic characterization. DNA-DNA homology among selected strains and the type strain ofV. cholerae was studied by the S1 endonuclease method. Seven sucrose-negative strains were shown to have the phenotypic properties of and a high percentage DNA relatedness toV. cholerae and a low level of homology withV. mimicus. Eight luminescent strains phenotypically most closely resembledV. mimicus; however, two of these were shown to have a high level of DNA homology withV. cholerae and a low level of relatedness toV. mimicus. A single strain was found to be phenotypically and genetically unrelated to eitherV. cholerae orV. mimicus and may represent a new species. The remaining strains were phenotypically shown to beV. mimicus, and selected strains were shown to have a high percentage DNA homology withV. mimicus and a low level of homology withV. cholerae. Problems associated with the identification of these strains and differential traits are discussed. |
