The Kinyoun method or Kinyoun stain (cold method), developed by Joseph J. Kinyoun, is a procedure used to stain acid-fast species of the bacterial genus Mycobacterium. [1] It is a variation of a method developed by Robert Koch in 1882. Certain species of bacteria have a waxy lipid called mycolic acid, in their cell walls which allow them to be ...
Ziehl–Neelsen staining is a type of narrow spectrum fungal stain. Narrow spectrum fungal stains are selective, and they can help differentiate and identify fungi. [10] The results of Ziehl–Neelsen staining is variable because many fungal cell walls are not acid fast. [11]
Ziehl–Neelsen stain (classic and modified bleach types) [5]; Kinyoun stain; For color blind people (or in backgrounds where detecting red bacteria is difficult), Victoria blue can be substituted for carbol fuchsin and picric acid can be used as the counter stain instead of methylene blue, and the rest of the Kinyoun technique can be used.
A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue .
Fixed costs and variable costs make up the two components of total cost. Direct costs are costs that can easily be associated with a particular cost object. [2] However, not all variable costs are direct costs. For example, variable manufacturing overhead costs are variable costs that are indirect costs, not direct costs. Variable costs are ...
Here's a comparison of fixed expenses vs. variable expenses to help you budget efficiently. ... also known as the 50/30/20 budgeting method. You can also change the percentage according to your ...
Variable costing is a managerial accounting cost concept. Under this method, manufacturing overhead is incurred in the period that a product is produced. This addresses the issue of absorption costing that allows income to rise as production rises. Under an absorption cost method, management can push forward costs to the next period when ...
