Kleborate

Klebsiella comprehensive AMR and typing analysis software.

About Kleborate

Current Kleborate version: v2.2.0.

For a detailed explanation about the Kleborate tool and outputs in general, please view their documentation at: http://bit.ly/kleborate-workshop.

The Kleborate software from Holt et al provides in depth species, ST, virulence genes, capsule typing and antimicrobial resistance prediction for Klebsiella. Results are displayed in the Genome Report and in the "Typing" table of the Collection View, and can be downloaded from both download menus.

Kleborate is focussed on the Klebsiella pneumoniae complex (KpSC). Typing and inexact virulence locus results for Klebsiella species outside of this complex should be treated with care.

The Kleborate output splits into four main sections:

1. Typing - Species/MLST and other typing outputs.

2. Virulence Locus Typing - Allele and ST codes for virulence loci.

3. Predicted AMR - AMR genes and alleles grouped by resistance phenotype.

4. Beta-Lactamase Genes By Class - BLA genes grouped by Lahey classes.

Each section is described below with links to the source documentation from Kleborate.

Typing

Species

The assigned species according to Kleborate. This can conflict with the output of Speciator, and is more likely to be correct.

Virulence/Resistance Score

Virulence (0-5) and resistance scores (0-3) determined by Kleborate.

K/O Locus

The K and O locus names and confidence in the assignments as determined by Kaptive. For references see below.

Virulence Locus Typing

The following virulence loci and types are determined by Kleborate:

• Yersiniabactin/YbST

• Colibactin/CbST

• Aerobactin/AbST

• Salmochelin/SmST

• RmpA, RmpA2 (hypermucoidy)
