Differential staining essay

Gram staining is a differential staining technique that differentiates bacteria into two groups: gram-positives and gram-negatives the procedure is based on the ability of microorganisms to retain color of the stains used during the gram stain reaction. Below is an essay on simple and differential staining of bacteria from anti essays, your source for research papers, essays, and term paper examples simple and differential staining of bacteria in previous exercises you have observed live bacteria via compound brightfield microscopy. Differential staining (use of 2 contrasting stains)it is divided into two groups: (a) separation into groups, gram stain and acid-fast stain (b) visualization of structures, flagella stain, capsule stain, spore stain, nuclear stain. Gram staining is a differential stain that helps in distinguishing between types of bacteria and it is the most useful staining procedure used today (seeley and others 1991) in this kind of staining procedure, a basic dye, a mordant, a decolorizing agent and a counterstain is needed.

Differential staining relies on the bacterial cell wall structure in order to differentiate the gram negative from the gram positive the latter has thick peptidoglycan stratum in the wall that has the ability to hold on to crystal violet stains following acetone or ethanol exposure or both at the same time. A differential staining technique is a procedure that allows the observer to visually distinguish between different types of bacterial cells based on the idea that not all cell types stain equally some physical characteristic leads to unequal uptake of a stain, depending on the specific bacteria. The best way to understand this concept is to look at the most famous differential staining technique, the gram stain the gram stain is a differential staining technique that can detect two different types of bacteria based on differences in the cell wall structure.

Differential calculus is a subfield of calculus that focuses on derivates, which are used to describe rates of change that are not constants the term ‘differential’ comes from the process known as differentiation, which is the process of finding the derivative of a curve differential calculus is a major topic covered in calculus. Differential staining purpose: the purpose of this experiment was to become familiar with subtypes of culture media and the uses for each, learn and employ the streak and pour dish techniques, and generate a pure culture of a specific organism.

Microscopy and differential staining essay 787 words jan 6th, 2014 4 pages 1what are the advantages and disadvantages of the different types of light and electron microscopes discussed in chapter 3 that are used to study microorganisms. Gram staining is a differential or specific method of staining gram staining is a way to tell the difference between gram positive and gram negative bacteria the cell wall of the gram positive bacteria is made up of several “layers of peptidoglygan,” and “techoic acids,” (labpaq, p 128.

The differential staining method enabled visualization of the thicker cell walled, gram-positive bacteria staphylococcus and lactobacillus, as well as the purple staining of the yeast s cerevisiae the color of s cerevisiae is noteworthy, as it is a fungus the rules of differential staining do not apply. The differential staining method enabled visualization of the thicker cell walled, gram-positive bacteria staphylococcus and lactobacillus, as well as the purple staining of the yeast s cerevisiae the color of s cerevisiae is noteworthy, as it is a fungus.

Simple staining (use of a single stain)this type of staining is used for visualization of morphological shape (cocci, bacilli, and spirilli) and arrangement (chains, clusters, pairs, and tetrads) 2 differential staining (use of 2 contrasting stains)it is divided into two groups: (a) separation into groups, gram stain and acid-fast stain.
