研究概览
简要总结
The purpose of the study is to identify the genetic closeness of NTM derived from patients living together and from their surrounding environment and to trace the temporal relationship between them.
详细描述
After NTM isolation is done by using culture, from patients' sputum/bronchoscopic samples and their environmental samples, whole genome sequencing (WGS) will be conducted for all NTM isolates. Phylogenetic analysis will be performed based on single nucleotide polymorphism (SNP) on each NTM.
