Gst Gram Staining Learning Objectives the Student Will Use Aseptic Techniques in the Safe Inoculation of Various Forms of Media
GSt Gram Staining Learning Objectives The student will Use aseptic techniques in the safe inoculation of various forms of media. Follow oral and written instructions and manage time in the lab efficiently. Use the bright field light microscope to view microbes under oil immersion, make accurate observations and appropriate interpretations and store the microscope according to lab procedures. Properly prepare a bacterial smear for accurate staining and describe the chemical basis for simple staining and negative staining. Background/Theory Differential staining distinguishes organisms based on their interactions with multiple stains. In other words, two organisms may appear to be different colors. Differential staining techniques commonly used in clinical settings include Gram staining, acid-fast staining, endospore staining, flagella staining, and capsule staining. This link to the OpenStax Microbiology text provides more detail on these differential staining techniques. (OpenStax CNX, 2018) The Gram stain is a differential staining procedure that involves multiple steps. It was developed by Danish microbiologist Hans Christian Gram in 1884 as an effective method to distinguish between bacteria containing the two most common types of cell walls. (OpenStax CNX, 2018) One type consists of an inner plasma membrane and a thick outer layer of peptidoglycan. The other type consists of a double phospholipid Figure 1 Simplified structures of Gram negative cells (left) and Gram positive bilayer with a thin layer of cells (right) peptidoglycan between the two. The Gram Staining technique remains one of the most frequently used staining techniques. The steps of the Gram stain procedure are listed below and illustrated in Figure. (OpenStax CNX, 2018) 1. -

QBC F.A.S.T. Auramine O Stain
QBC F.A.S.T.TM Auramine O Stain Kit Instruction Manual 4277-400-053 Rev. I Revised 2018-11-20 English QBC F.A.S.T.TM Auramine O Stain Kit Intended Use For use as a stain for smears made from patient specimens or cultures in the detection or characterization of acid fast bacilli such as Mycobacterium tuberculosis. Summary and Principles The worldwide incidence of tuberculosis has been on an increasing trend since at least 1990, when the World Health Organization began tracking incidence data1. Early and accurate detection of tuberculosis is critical for both effective control and treatment of the disease. The most common method for detection of Mycobacterium tuberculosis is the use of sputum smear microscopy1, which can provide both an initial presumptive diagnosis as well as a quantification of the mycobacterial load. Acid fast bacilli, such as Mycobacterium tuberculosis, can be stained by aniline dyes and are resistant to decolorization by acid and alcohol. When followed by a counterstain, this treatment results in the acid fast bacilli staining with contrast to other organisms and debris that have retained only the counterstain. However, the staining methods classically used for acid fast microscopy result in a smear that can be difficult and time consuming to read. Auramine O and auramine-rhodamine stains have been successfully used for fluorescence based microscopy of mycobacteria. Reports of mechanism of staining are conflicting; these include Auramine O binding to the cell wall of the mycobacteria2 and the stain binding 1 to “most if not all” the Auramine O binding to the nucleic acid in the mycobacteria3. -

However, due to limited laboratory facilities that can satisfy the procedure, applicability of this procedure appears to be adversely affected in field conditions and at peripheral health institutions. Hence, it has become necessary to look for a procedure which can be used as alternative in such conditions. Material and Methods: This was a cross sectional study conducted in the Department of Microbiology, Index Medical College Hospital & Research Centre, Indore, Madhya Pradesh in conjunction with the Chest TB Clinic of Index Hospital, New Delhi for a period of 1year [from February 2018 to January 2019]. -

Eosin Staining
Science of H & E Andrew Lisowski, M.S., HTL (A.S.C.P.) 1 Hematoxylin and Eosin Staining “The desired end result of a tissue stained with hematoxylin and eosin is based upon what seems to be almost infinite factors. Pathologists have individual preferences for section thickness, intensities, and shades. The choice of which reagents to use must take into consideration: cost, method of staining, option of purchasing commercially-prepared or technician-prepared reagents, safety, administration policies, convenience, availability, quality, technical limitations, as well as personal preference.” Guidelines for Hematoxylin and Eosin Staining National Society for Histotechnology 2 Why Do We Stain? In order to deliver a medical diagnosis, tissues must be examined under a microscope. Once a tissue specimen has been processed by a histology lab and transferred onto a glass slide, it needs to be appropriately stained for microscopic evaluation. This is because unstained tissue lacks contrast: when viewed under the microscope, everything appears in uniform dull grey color. Unstained tissue H&E stained tissue 3 What Does "Staining" Do? . Contrasts different cells . Highlights particular features of interest . Illustrates different cell structures . Detects infiltrations or deposits in the tissue . Detect pathogens Superbly contrasted GI cells Placenta’s large blood H&E stain showing extensive vessels iron deposits There are different staining techniques to reveal different structures of the cell 4 What is H&E Staining? As its name suggests, H&E stain makes use of a combination of two dyes – hematoxylin and eosin. It is often termed as “routine staining” as it is the most common way of coloring otherwise transparent tissue specimen. -

Auramine O C.I. 41000
AURAMINE O C.I. 41000 IVD In vitro diagnostic medical device Basic Yellow 2, BSC certified stain For staining acid-fast lung tissue bacteria acc. to Truant INSTRUCTIONS FOR USE REF Product code: AU-P-25 (25 g) Introduction Histology, cytology and other related scientific disciplines study the microscopic anatomy of tissues and cells. In order to achieve a good tissue and cellular structure, the samples need to be stained in a correct manner. Auramine O powder dye is used in various staining methods in microscopy. It is used in clinical microbiology and histology for detecting tuberculosis Mycobacteria and other acid-fast bacteria. Staining using Auramine O is a fluorescent method of visualizing acid-fast bacteria. Mycobacteria are difficult to stain due to high amount of lipids and wax in their cellular membranes. When stained using Auramine O dye, acid-fast mycobactera retain the dye even when exposed to strong destaining solutions, such as HCl-ethanol. Product description AURAMINE O - Biological Stain Commission (BSC) certified powder dye for preparing solution for detecting Mycobacterium tuberculosis and other acid-fast bacteria Other preparations and reagents used in preparing the dye solution: Microscopy powder dyes, such as BioGnost's Rhodamine B dye (product code RHB-P-25) Phenol (C6H5OH) Glycerol (C3H5(OH)3) Preparing the solutions for staining Auramine O-Rhodamine B staining solution: Dissolve by mixing 3 g of Auramine O powder dye adn 1.5 g of Rhodamine B powder dye in 150 ml of glycerol at room temperature. Add 20 ml of molten phenol (at 45oC) and 100 ml of distilled/demineralized water After mixing, filter through glass wool Results Tb bacterija (ARB) - red or greenish fluorescence Background - dark Note The mentioned formulation is only one of the ways of preparing the dye solution.
