A bioinformatics pipeline for Mycobacterium tuberculosis sequencing that cleans contaminant reads from sputum samples.

Next-Generation Sequencing (NGS) is widely used to investigate genomic variation. In several studies, the genetic variation of Mycobacterium tuberculosis has been analyzed in sputum samples without previous culture, using target enrichment methodologies for NGS. Alignments obtained by different programs generally map the sequences under default parameters, and from these results, it is assumed that only Mycobacterium reads will be obtained.

COVID-19 and Tuberculosis Coinfection in a 51-Year-Old Taxi Driver in Mexico City.

BACKGROUND Coinfection with severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2) and Mycobacterium tuberculosis (MBT) has been reported, albeit rarely, in various parts of the world and has received attention from health systems because up to one-third of the world's population has been infected with SARS-CoV-2. Mexico was not included in the first-ever report on a global cohort of patients with this coinfection. We report on a case of SARS-CoV-2/MBT coinfection in a 51-year-old taxi driver from Mexico City that underscores the importance of rapid and accurate laboratory testing, diagnosis, and treatment.
