分枝桿菌屬(學名:Mycobacterium)為放線菌門的一屬細菌,且為分枝桿菌科唯一的屬。為形狀不規則的革蘭氏陽性桿菌,不能游動,通常抗酸,無氣生菌絲和孢子。

該屬細菌包括許多已知在哺乳類動物中造成嚴重疾病的病原菌,包括結核桿菌(Mycobacterium tuberculosis)和麻風桿菌(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]
2018年,基於全基因組測序的數據,對分枝桿菌屬進一步進行修訂,並拆分出4個新的菌屬,即Mycolicibacillus、Mycolicibacter、Mycobacteroides和Mycolicibacterium。[3]
微生物特徵
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內孢子或莢膜,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)[4]。但進一步的研究引發了爭論。[5]
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。[6]
物種
表型測試可用於識別和區分不同的分枝桿菌物種和菌株。在以前的系統中,分枝桿菌根據它們的外觀和生長速度進行分組的。然而,這些是近祖共性(symplesiomorphies)的,並且最近的分類基於支序分類學(cladistics)進行的。
