Colorado Cystic Fibrosis Research & Development Program

Colorado CF RDP Molecular and Genomics Core

The ability to identify, analyze, and compare isolates within the same subspecies of M. abscessus or MAC is central to understanding the diversity of infectious disease pathogens and identifying the occurrence of possible patient-to-patient transmission within CF Centers. Analysis is also needed to identify the possibility of a shared source of environmental exposure, or to rule-out such an environmental source. Thus, genomic sequencing and phylogenomic analysis of isolates is essential to identify outbreaks and limit their occurrence and spread.

The Molecular Core accepts samples from the NTM Culture, Biorepository, and Coordinating Core. Samples are analyzed using whole genome sequencing (WGS) and comparative phylogenomic methods. These results are communicated back to the NTM Culture, Biorepository, and Coordinating Core, for dissemination to the referring Centers. The primary goal of the Molecular Core is to characterize the diversity and prevalence of NTM species affecting the CF community, and to accurately identify and limit potential instances of patient-to-patient transmission or nosocomial acquisition events in CF Centers.
