Resolving Power

 Resolving Power
   It is closest distance between two points at which  the point can be seen clearly & separate as entities. It is ability to distinguish two objects as a separate entities.
R.P = _lamba___
              2NA                                


The smaller value for resolving power, the smaller object can be seen distinctly. The highest resolution  possible in a compound microscope is about 0.22 micrometer. This means that two object closer than 0.22 micrometer aren't resolvable as distinct & separate. Shorter the wavelength  of illuminating the specimen,  greater is the resolving power, better the resolving power so that smaller objects can be viewed.

Stains/ Dyes

STAINS/ DYES
     They are colored organic compounds used for staining microorganisms. Chemically,
Stains= Benzene ring+ Chromophore+ Auxochrome

According to nature of stain, it can be classified into:

1. Acidic Dyes:   It is dye which has negative charge so they bind to positively charged cell structures like some proteins. Acidic dyes are not very often used in Microbiology lab.except to provide background staining like Capsule staining. Examples: Nigrosine, Picric acid, Eosin, Acid fuschin, India ink etc. 

2. Basic Dyes:  This dye have positive charge & bind to negatively charged molecules(nucleic acid, -COOH -OH). Since, surface  of bacterial cells are negatively charged(due to Teichoic acid), basic dyes are most commonly used in bacteriology. Examples: Crystal Violet, Methylene Blue, Safranin , basic fuschin.

3. Neutral Dyes:  They are usually formed from precipitation in which are produced when aqueous acidic & basic stains are combined. Neutral dyes stains nucleic acid…

Fixation

Fixation
   The stained cells in a microscope should resemble living cells as closely as possible. Fixation is process by which the internal & external structures of cells & microorganisms are preserved & fixed.  It inactivates enzymes that might disrupt cell morphology & toughens cell structures so that they don't change during staining & observation. A microorganism is usually  killed & firmly attached  to microscopic slide during fixation.
       There are two fundamentally different types of fixation.  Bacteriologists heat fix bacterial smear by gentle  & an air dried film of bacteria. This adequately overall morphology  but not structures within cells. Chemicals fixation must be used to protect  fine cellular structures & the morphology of larger, more delicate microorganisms. Chemical fixatives penetrate cells & react with cellular  components, usually proteins,lipids to render them inactive, insoluble & immobile.  Common fixatives  m…

Contributions Of Antony Van Leeuwenhoek & Louis Pasteur

Contributions Of  Antony Van Leeuwenhoek
1. He first discovered & reported bacteria(1676).
2. Observed Microscopic structure of seeds & embryos of plants & some invertebrates.
3. He discovered Spermatozoa & RBCs.
4. He discovered characteristic microbes of human mouth, curd, vinegar.
5. Emphasized the abundance of these microorganisms..

Contributions Of  Louis Pasteur

1.Disproved the theory of Spontaneous Generation.
2. Developed vaccines against Rabies, Anthrax, & Cholera.
3.Devised the purposes of destroying bacteria's by Pasteurization .
4. Proposed  Germ Theory Of Disease.
5. Helped to improve the fermentation process during hi period in France.
6. Known As Father Of  Microbiology.
