分枝杆菌属
分枝杆菌科的一属细菌
分枝杆菌屬(Mycobacterium)為放线菌门下的一個屬,且為分枝桿菌科唯一的屬。为形状不规则的革兰氏阳性杆菌,不能游动,通常抗酸,无气生菌丝和孢子。

该属细菌包括许多已知在哺乳類动物中造成严重疾病的病原菌,包括结核杆菌(Mycobacterium tuberculosis)和麻风杆菌(Mycobacterium leprae)[1]。
希臘語中的 myco 表示「真菌」,意思是說該屬的物種通常在液態培養基的表面,形成類似黴菌的菌落。[2]
微生物特徵编辑
微生物細胞壁:
1. 外層脂質
2. mycolic acid
3. 多醣(arabinogalactan)
4. 肽聚糖
5. 細胞膜
6. lipoarabinomannan(LAM)
7. phosphatidylinositol mannoside
8. 細胞壁骨架

本屬物種為好氧型細菌,且為不運動型細菌(海洋分枝桿菌除外,其可以在巨噬細胞內運動),為一種抗酸型細菌[1]。分枝桿菌並不會形成内孢子或莢膜,因此常被認定為革蘭氏陰性菌。且分枝桿菌在革蘭氏染色上並無法染上結晶紫,因此無法被歸類於革蘭氏陽性菌或陰性菌。
雖然說本屬不產孢子,但有兩個物種似乎例外,那就是海洋分枝桿菌(Mycobacterium marinum)和牛分枝桿菌(M. bovis)[3]。但進一步的研究引發了爭論。[4]
分枝桿菌的特點就是其細胞壁較其他物種厚,且呈蠟狀疏水性,並含有大量的分枝菌酸(mycolic acids)。多醣會將分枝菌酸層及肽聚糖層拉在一起,讓細胞壁變得十分堅韌。若可干擾其細胞壁的生物合成途徑,也許可以開發治療肺結核的藥物。[5]
物種编辑
Phylogenetic Position of the Tubercle Bacilli within the Genus Mycobacterium The blue triangle corresponds to tubercle bacilli sequences that are identical or differing by a single nucleotide. The sequences of the genus Mycobacterium that matched most closely to those of M. tuberculosis were retrieved from the BIBI database (http://pbil.univ-lyon.fr/bibi/[永久失效連結]) and aligned with those obtained for 17 smooth and MTBC strains. The unrooted neighbor-joining tree is based on 1,325 aligned nucleotide positions of the 16S rRNA gene. The scale gives the pairwise distances after Jukes-Cantor correction. Bootstrap support values higher than 90% are indicated at the nodes.
表型测试可用于识别和区分不同的分枝杆菌物种和菌株。在以前的系统中,分枝杆菌根据它们的外观和生长速度进行分组的。然而,这些是近祖共性(symplesiomorphies)的,并且最近的分类基于支序分类学(cladistics)进行的。
