Previously, Burkholderia and Stenotrophomonas species were classified as Pseudomonas due to their similar biochemical properties. In 1992, the genus Burkholderia was proposed for 7 species. There has been a rapid increase in newly identified species to > 70 species that are very similar phenotypically, thus making taxonomic classification somewhat perplexing without the use of molecular strategies. The most commonly identified species within the Burkholderia cepacia complex are Burkholderia cenocepacia and Burkholderia multivorans. Stenotrophomonas was initially reclassified as Xanthomonas in 1983 and acquired its present classification in 1993. Stenotrophomonas maltophilia is the only species within its genus known to cause human disease.
