Diagnosis, differentiating colonization, infection, and disease.

摘要: Nontuberculous mycobacteria (NTM) are found commonly in respiratory specimens. In many clinical laboratories, the majority of recovered from samples NTM. Perhaps this is because NTM common environment. The water that we drink or shower often contains NTM; consequently, find secretions. term colonization has been used when more than once even though a specific disease cannot be demonstrated. Under these circumstances, it never quite clear whether low-grade infection exists if secretions simply contaminated by environmental organisms; however, can discerned focusing on elements making diagnosis an NTM-related disease, rather finding organism samples.
