Abstract

Seventeen representative strains of and related taxa were analyzed for antigenic relationships by rocket Immunoelectrophoresis. A good correlation was found between data from this form of analysis and previously reported numerical phenetic and deoxyribonucleic acid reassociation data. and strains formed distinct clusters in a dendrogram produced by average linkage analyses for dissimilarity matrices. , and an unidentified strain formed single-member clusters, whereas was found to be heterogeneous. In contrast, . and . were found to be distinct species. The discrepancies between deoxyribonucleic acid pairing and rocket Immunoelectrophoresis results can be explained on the basis of suboptimal antigen or antiserum preparations.
