마이코박테리움 (Mycobacterium) 속에는 결핵, 우형결핵, 나병과 같이 사람과 동물에 심각한 질병을 일으키는 균 종 (species)뿐 아니라, 기회 감염균으로 일컬어지는 균 종, 그리고 자연환경에서 볼 수 있는 사물 기생의 균 종 (saprophytic species) 등 현재까지 약 72 종(species)이 알려져 있으며, 그 중 인체 질환과 관련된 것이 25종에 이르는 것으로 알려져 있다. 이러한 마이코박테리움 속은 일반적으로 사용되는 염색액으로는 용이하게 염색되지 않지만 일단 염색되면 알코올이나 염산 등으로 처리시에도 용이하게 탈색되지 않기 때문에 항산균이라고도 불린다.Mycobacterium includes not only species that cause serious diseases in humans and animals, such as tuberculosis, tuberculosis bovine tuberculosis, and leprosy, but also fungal species called opportunistic bacteria, and parasitic objects found in the natural environment. About 72 species such as saprophytic species are known so far, of which 25 are known to be related to human diseases. These Mycobacterium genus are not easily dyed with commonly used dyeing solutions, but once dyed, they are also called acid-fighting bacteria because they are not easily decolorized even when treated with alcohol or hydrochloric acid.
비결핵 항산균(Nontuberculous mycobacteria; NTM)은 결핵균(Mycobacterium tuberculosis complex) 및 나균(Mycobacterium leprae)을 제외한 항산균을 의미한다. 한편, 마이코박테리움 아비움 복합체(Mycobacterium avium complex; MAC)에 속하는 비결핵 항산균주 중 흔히 인간에게서 폐 질환을 일으키는 균주로는 공식적으로 대략 180 종 이상이 규명되었다. MAC는 주로 M. 아비움(M. avium)과 M. 인트라셀룰라(M. intracellulare)를 포함하고, 마이코박테리움 압세수스(Mycobacterium abscessus; MAB)는 주로 M. 압세수스 아종인 압세수스(M. abscessus subspecies abscessus)와 M. 압세수스 아종인 마실리엔시스(M. abscessus subspecies massiliense)를 포함한다. 최근 전세계적으로 비결핵 항산균에 기인한 폐 감염 보고가 증가하고 있지만, 건강한 개체군으로부터 비결핵 항산균 폐 감염 질환자를 구별하기 위한 바이오마커나, 질환에 대한 병태 생리의 연구가 부족한 실정이다.Nontuberculous mycobacteria (NTM) refers to mycobacteria other than Mycobacterium tuberculosis complex and Mycobacterium leprae. Meanwhile, among non-tuberculous mycobacteria belonging to the Mycobacterium avium complex (MAC), more than 180 strains have been officially identified as strains that commonly cause lung disease in humans. MAC mainly contains M. avium and M. intracellulare, and Mycobacterium abscessus (MAB) mainly contains M. abscessus subspecies Absesu. s (M. abscessus subspecies abscessus) and M. abscessus subspecies massiliense (M. abscessus subspecies massiliense). Recently, reports of lung infections caused by non-tuberculous mycobacteria have been increasing worldwide, but biomarkers for differentiating non-tuberculous mycobacterial lung infections from healthy populations or pathophysiology studies of diseases are lacking.

The equipment used was an Agilent 1200 HPLC and a Sciex API4000 triple quadrupole MS. As chromatography conditions for the hydrophilic interaction, polar metabolites were separated by gradient elution in two methods depending on the solvent at 20 °C using a Luna PFPP (2.0 x 150 mm, 3 μm, Phenomenex) column. (A) H 2 O (v/v) and (B) acetonitrile (v/v) were used as the first mobile phase, and (A) H 2 O (v/v, 0.1% formic acid) as the second mobile phase and (B) acetonitrile (v/v) were used, and the gradient elution of each condition was performed in the same manner as in Table 1 below with a total analysis time of 15 minutes. The unit of the Ion-Source Gas 1/2 was 50/50 arbitrary units, and the unit of the Curtain Gas was 25 arbitrary units. The source temperature was 500 °C, the ion-spray floating voltage was 5.5 kV (negative -4.5 kV), and the mass range was 50 ~ 1000 m/z. Samples were injected by 3 μl using HTC_PAL system/CTC analytics auto-sampler, and tandem mass spectrometry conditions (Scheduled Multiple Reaction Monitoring, sMRM) were performed as shown in Tables 2 and 3 below. However, in Tables 2 and 3, m/z means mass to charge ratio, RT means retention time, CE means collision energy, (+) means positive ion mode and (-) means negative ion mode.
