Stenotrophomonas ssp. has a wide environmental distribution and is also found as an opportunistic pathogen, causing nosocomial or community-acquired infections. One species, S. maltophilia , presents multidrug resistance been associated with serious infections in pediatric immunocompromised patients. Therefore, it relevant to conduct profile phylogenetic studies clinical isolates for identifying infection origins augmented pathogenic potential. Here, multilocus sequence typing was performed analysis of spp. and, strains . Biochemical profiles were determined. The inferred showed high clonal variability, what correlates the adaptability process different habitats. Two subgroups sharing homogeneity presented intergroup recombination, thus indicating permittivity horizontal gene transfer, mechanism involved acquisition antibiotic expression virulence factors. For most strains, inference made using only partial pps A sequence. sequencing just one specific fragment this would allow, many cases, determining whether community-acquired.
