But it stains pretty weakly as a Gram-negative bacteria, so it's best visualized with silver stain.

但革兰氏染色阴性的表现很弱，因此最好用银染色观察。

It's a non-spore forming, aerobic, facultative intracellular, catalase and oxidase positive bacteria that is best visualized with silver stain and grows well on BCYE agar with cysteine and iron into grey-white colonies with a cut-glass appearance.

它是非芽孢、需氧、兼性细胞内寄生、氧化酶和过氧化氢酶阳性的细菌；最佳观察方式是银染色；在BCYE培养基供给半胱氨酸和铁的情况下生长良好，可形成雕花玻璃样的灰白色菌落。
