[Analysis of principal coordinates and factorial correspondence analysis applied to the taxonomy of type strains of Desulfovibrio].
Bacterial taxonomy using mathematical methods can be carried out with different techniques. Two techniques are used in this paper: analysis of principal coordinates and factor analysis of correspondences. The first one allows 2 and 3 dimension graphs of bacteria, thus showing their relationship considering proximity. The second one gives new data because it is an analysis which allows to connect bacteria to the reactions which identify them. In order to carry out these analyses 14 strains of the Desulfovibrio genus were studied, thus obtaining a classification consistent with other numeric method (group analysis with Simple Matching coefficient of average bond) to which it adds new information.
