Spread Plate Technique- Principle, Procedure and Uses 4.24/5 (42)

Spread Plate Technique- Principle, Procedure and Uses

Spread Plate Technique- Principle, Procedure and Uses Spread plate technique is the method of isolation and enumeration of microorganisms in a mixed culture and distributing it evenly. The technique makes it easier to quantify bacteria in a solution.  Principle of Spread Plate Technique The spread plate technique involves using a sterilized spreader with a smooth […]

Differences Between Bacteria and Viruses 4.16/5 (461)

Differences Between Bacteria and Viruses

Differences Between Bacteria and Viruses Although bacteria and viruses both are very small to be seen without a microscope, there are many differences between Bacteria and Viruses. Some of the Differences Between Bacteria and Viruses are as follows: S.N. Characteristics Bacteria Viruses 1 Size Larger (1000 nm) Smaller (20-400 nm) 2 Cell Wall Peptidoglycan or […]

Top and Best Microbiology Books

Top and Best Microbiology Books Here are some of the top, nice and good microbiology books which we can study to get the basic as well as some advance knowledge of systemic and diagnostic microbiology. These are arranged randomly because one choices of best book may be different from the choice of other. But I […]

Techniques of Virus Cultivation 4.42/5 (272)

Inoculation into embryonated egg

Techniques of Virus Cultivation Viruses are obligate intracellular parasites so they depend on host for their survival. They cannot be grown in non-living culture media or on agar plates alone, they must require living cells to support their replication. The primary purpose of virus cultivation is: To isolate and identify viruses in clinical samples. To […]

Differences Between Exotoxins and Endotoxins 4.63/5 (725)

Differences Between Exotoxins and Endotoxins

Differences Between Exotoxins and Endotoxins Many bacteria produce toxins, enzymes and pigments. Toxins and enzymes play important role in pathogenecity. Toxins are of two types: Exotoxins are usually heat labile proteins secreted by certain species of bacteria which diffuse into the surrounding medium. Endotoxins are heat stable lipopolysaccharide-protein complexes which form structural components of cell […]

Differences Between Cilia and Flagella 4.26/5 (121)

Differences Between Cilia and Flagella

Differences Between Cilia and Flagella Flagella are the complex filamentous cytoplasmic structure protruding through cell wall. These are unbranched, long, thread like structures, mostly composed of the protein flagellin, intricately embedded in the cell envelope. Cilia are slender, microscopic, hair-like structures or organelles that extend from the surface of nearly all mammalian cells (multiple or […]

Differences between Gram Positive and Gram Negative Bacteria

Differences between Gram Positive and Gram Negative Bacteria S.N. Characteristics Gram Positive Gram Negative 1 Gram Reaction Retain crystal violet dye and stain blue or purple Can be decolorized to accept counterstain (safranin) and stain pink or red 2 Cell Wall Cell Wall is 20-30 nm thick. Cell Wall is 8-12 nm thick. 3 Cell […]

Different Size, Shape and Arrangement of Bacterial Cells 4.39/5 (332)

Different Size, Shape and Arrangement of Bacterial Cells

Different Size, Shape and Arrangement of Bacterial Cells Bacteria are prokaryotic, unicellular microorganisms, which lack chlorophyll pigments. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Due to the presence of a rigid cell wall, bacteria maintain a definite shape, though they vary as shape, size and […]

Haemolysis of Streptococci and its types with examples 4.48/5 (130)

Haemolysis of Streptococci and its types with examples

Haemolysis of Streptococci and its types with examples Hemolysis is the breakdown of red blood cells (RBC). A substance that causes hemolysis is a hemolysin. Brown (1919) introduced three terms alpha, beta and gamma to indicate three types of streptococci based on haemolytic reactions observed on blood agar plates. Beta-hemolytic Streptococci Source : Bacteria in Photos […]
