RESUMO

The genus Stenotrophomonas is found in the respiratory treatment of patients with chronic pulmonary and also in the rizhosfera of plants. It presents resistance to several antibiotics, promotes the growth of plants and some species present the ability to fix atmospheric nitrogen. The Multi Locus Sequence Analysis (MLSA) is a methodology based on constitutive genes for definition and taxonomic allocation of new species. The general objective of the present work was to characterize a wide collection constituted by Stenotrophomonas from isolated endophytic, type and reference strains. In such a way, a system of classification and identification of Stenotrophomonas by means of MLSA was established. It was possible through the MLSA methodology to define 9 new species, to detect the presence of a new genus and to establish an online system for Stenotrophomonas taxonomy.
