革兰氏染色(Gram Staining)的详解 革兰氏染色的定义与背景 革兰氏染色,又称革兰氏染色法,是一种用来鉴别细菌的重要方法。该方法由丹麦医生汉斯·克里斯蒂安·革兰于1884年发明,最初用于鉴别肺炎球菌与克雷白氏肺炎菌之间的关系。革兰氏染色利用细菌细胞壁上的生物化学性质不同,将细菌分为革兰...
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...

Related to gram-positively:Gram staining gram-positive [gram-poz´ĭ-tiv] retaining the stain or resisting decolorization by alcohol in Gram's method of staining; seeGramstain. This is a primary characteristic of bacteria whose cell wall is composed ofpeptidoglycanandteichoic acids. ...
Gram positive vs Gram negative refers to the cell wall structure of different bacteria. Gram staining refers to a staining procedure that was developed by Hans Christian Gram. This staining procedure renders Gram positive bacteria purple and Gram negative bacteria red or pink. Gram staining is impor...
METHODS Sodium hydroxide smear of the liquid of lymphonodus puncture, Gram staining, Sabouraud′s culture and series of identification were carried out. 结果 氢氧化钠涂片和革兰染色能检出马尔尼菲青霉菌所特有的孢子。 6) gram-positive 革兰阳性
Gram stain is probably one of the most commonly used staining procedures used in the field of microbiology. It is one of the differential stains that are used to characterize bacteria in one of two groups: either gram positive bacteria or gram negative bacteria. ...
THE direct observation of the site of Gram stain in cells of micro-organisms could not be attempted before the ultra-thin section technique became available. However, to obtain a suitable section, specimens have to be dehydrated either by alcohol or by a water-miscible resin (for example, `...
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, Gram negative bacteria have an...
Many biologists have likely encountered the terms "Gram-positive" and "Gram-negative" bacteria, but what do these terms mean and what are their implications for human health and disease? The Gram Staining Test The Gram staining testwas invented in 1884 by Hans Christian Gram. The test character...
