Optimizing hybrid assembly of next-generation sequence data from Enterococcus faecium: a microbe with highly divergent genome.

ABSTRACT:

Background

Sequencing of bacterial genomes became an essential approach to study pathogen virulence and the phylogenetic relationship among close related strains. Bacterium Enterococcus faecium emerged as an important nosocomial pathogen that were often associated with resistance to common antibiotics in hospitals. With highly divergent gene contents, it presented a challenge to the next generation sequencing (NGS) technologies featuring high-throughput and shorter read-length. This study was designed to investigate the properties and systematic biases of NGS technologies and evaluate critical parameters influencing the outcomes of hybrid assemblies using combinations of NGS data.

Results

A hospital strain of E. faecium was sequenced using three different NGS platforms: 454
