Phospholipid molecular species present in 32 isolates of Clostridium difficile were examined by fast atom bombardment-mass spectrometry in negative-ion mode. This revealed major anions consistent with the expected presence of the following phosphatidylglycerol (PG) analogs: PG(31:2), PG(32:1), PG(33:2), PG(33:1), PG(34:2), and PG(34:1). The major phospholipid molecular species are distinct from those of other bacterial groups examined.
采用快原子轰击质谱负离子模式,对32株艰难梭菌分离株中存在的磷脂分子种类进行了检测。结果显示,主要阴离子与以下磷脂酰甘油(PG)类似物的预期存在情况一致:PG(31:2)、PG(32:1)、PG(33:2)、PG(33:1)、PG(34:2)和PG(34:1)。主要的磷脂分子种类与所检测的其他细菌类群不同。
