Abstract

We used numerical taxonomy procedures to analyze data obtained from 227 strains belonging to either the genus or related genera; included were pathogenic and nonpathogenic vibrios isolated from a variety of samples and geographic locations. Each strain was tested for 150 unit characters. At a similarity coefficient of 70 to 75% or more, the 227 strains clustered into 33 phena, representing , and new species of . Non-O1 and O1 serovars of clustered at the species level of relationship (i.e., at a similarity coefficient of ≥75%). Furthermore, subdivision of into classical, El Tor, , and biovars was not observed. In fact, the biovar was found to warrant separate species status as . Only the sucrose-negative members of Heiberg group V were distinguishable as a separate cluster and were recognized as a separate biovar. Sucrose-positive strains and urease-positive strains of were identified. The differences among the four groups of examined did not warrant recognition of biovars.
