Randomized trial analyzes genetic clustering of Legionella pneumophila isolates, suggesting simplified workflows can enhance isolate characterization.

Key Points

This research aims to evaluate the effectiveness of accessible single-step WGS analysis tools for genetic clustering of Legionella pneumophila isolates compared to traditional methods.
Analyzed 19 environmental Legionella pneumophila isolates using whole genome sequencing (WGS).
Compared results from an established multi-step bioinformatic pipeline with several accessible single-step analysis tools.
Assessed clustering patterns and genetic relatedness of isolates across different spatial sampling partitions.
Both single-step and multi-step bioinformatic tools produced consistent genetic clustering, resolving isolates into two major clusters.
No clear spatial correlation was found between distances of isolate sampling and their genetic relatedness.
WGS approaches provided clustering resolution similar to MLST/cgMLST despite lower analytical complexity.
