Abstract
MARTINEZ-ROMERO, Esperanza et al. Klebsiella variicola and Klebsiella quasipneumoniae with capacity to adapt to clinical and plant settings. Salud pública Méx [online]. 2018, vol.60, n.1, pp.29-40. ISSN 0036-3634. https://doi.org/10.21149/8156.
Objective:
To compare the genetic determinants involved in plant colonization or virulence in the reported genomes of K. variicola, K. quasipneumoniae and K. pneumoniae.
Materials and methods:
In silico comparisons and Jaccard analysis of genomic data were used. Fimbrial genes were detected by PCR. Biological assays were performed with plant and clinical isolates.
Results:
Plant colonization genes such as cellulases, catalases and hemagglutinins were mainly present in K. variicola genomes. Chromosomal β-lactamases were characteristic of this species and had been previously misclassified. K. variicola and K. pneumoniae isolates produced plant hormones.
Conclusions:
A mosaic distribution of different virulence- and plant-associated genes was found in K. variicola and in K. quasipneumoniae genomes. Some plant colonizing genes were found mainly in K. variicola genomes. The term plantanosis is proposed for plant-borne human infections.
