About Kaptive

Kaptive is a tool for Klebsiella locus typing and variant evaluation. It takes one or more pre-assembled genomes and for each finds the best matching locus from a reference database. References for known K-loci (capsule) and O-loci (lipopolysaccharide) are available in Kaptive's web interface.
