title: Reassessment of Stenotrophomonas maltophilia phenotype.
abstract: Standard microbiology references describe Stenotrophomonas maltophilia as oxidase negative and variable with respect to utilization of lactose and sucrose. Analysis of a collection of 766 S. maltophilia isolates indicated that approximately 20% are oxidase positive and that this species should be reevaluated for other phenotypes, including oxidative fermentation of lactose and sucrose.
