The Influence of Carbohydrates on the Virulence Potential of <i>Klebsiella variicola</i> Isolates.

ABSTRACT: Klebsiella variicola is a Gram-negative bacillus belonging to Enterobacteriaceae recognized as an emerging human pathogen in the last years. The species is frequently misidentified as Klebsiella pneumoniae by conventional microbiological tests, raising questions about its real prevalence and clinical impact. K. variicola virulence is mediated by traits that are expressed in human body niches containing different nutrients, including carbohydrates, that influence their expression. In this way, we analyzed the effect of different carbohydrates on the expression of virulence traits by K. variicola isolates. For this approach, three classical strains (cKv15, cKv35, and cKv57) and one hypermucoviscous (HMV) were submitted to growth curve characterization, biofilm pro
