title: Identical 5S rRNA nucleotide sequence of Vibrio cholerae strains representing temporal, geographical, and ecological diversity.
abstract: Enzymatic determination of the nucleotide sequence of 5S rRNA prepared from a Vibrio cholerae non-O1 serovar isolated from a canal in Louisiana in 1978 revealed it to be identical to that of V. cholerae O1 isolated in 1905 from a pilgrim at the E1 Tor quarantine station. The two strains are associated with sharply contrasting habitats. Ranges of variation of 5 to 15% in procaryotic 5S rRNA sequences between species are typical; variation within species may be 2% or greater. Because the 5S rRNA sequences were identical, it is concluded that they have a common phylogenic origin.
