革兰氏染色(Gram Staining)是用来鉴别细菌的一种方法:这种染色法利用细菌细胞壁上的生物化学性质不同,可将细菌分成两类,即革兰氏阳性(Gram Positive)与革兰氏阴性(Gram Negative)。最初是用来鉴别肺炎球菌与克雷白氏肺炎菌之间的关系,后广为鉴别细菌种类的重要特性之一,对由细菌感染引起的疾病的临床诊断及治疗有着广泛...

Any bacteria that may be present are categorized by color and shape during the microscopic evaluation: Color — typically bacteria may be either “Gram positive” (purple) or “Gram negative” (pink) Shape — the most common shapes include round (cocci) or rod-shaped (bacilli) Additional ...
A method to determine the Gram sign of microorganisms includes staining the microorganisms with a plurality of fluorescent dyes in the presence of a staining buffer, applying excitation energy to the stained microorganisms, observing the color of the fluorescence emission of the stained microorganisms, ...
color of the counterstain during Gram staining. The cell wall structure of Gram negative bacteria is more complex than that of Gram positive bacteria. Located between the plasma membrane and the thin peptidoglycan layer is a gel-like matrix called periplasmic space. Unlike in Gram positive bacteria...
