Mycobacterium xenopi is a Gram-positive (acid-fast), slowly growing, thermophilic mycobacterium in the family Mycobacteriaceae, with an optimal growth temperature of approximately 45 degrees C. It is a non-tuberculous mycobacterium (NTM) found in hot-water systems and hospital water supplies, and is an important cause of chronic pulmonary disease, particularly in individuals with pre-existing lung damage. M. xenopi has a moderately sized mycobacterial genome and is phylogenetically placed in a distinct slow-growing clade with limited genetic diversity among clinical isolates.
For detailed methods on how these thresholds were calculated, please see Methods. The suggested thresholds are in the table below. These thresholds are based on 2 genomes from RefSeq and 0 genomes from other sources.
These tables provide a summary of the distribution of each metric, including SDeviation, Mean, Median, and Percentiles.

This plot shows the relationship between the number of coding sequences (CDS) and genome size. It helps to visualize how genome size correlates with the number of genes. This should be linear – as genome size increases, the number of coding sequences should also increase. Any secondary trend lines or non-linear behaviour indicates bona fide separate populations within the retained genomes or some remaining contaminant.
Histogram comparing SRA to RefSeq; each bar shows genome density across value ranges to highlight shifts, peaks, or outliers.
QQ (quantile-quantile) plot comparing SRA and RefSeq. Points along the diagonal follow the expected distribution; deviations indicate skew, outliers, or other systematic differences.
