History of Confocal Microscope In 1951, while a postdoctoral scholar at Harvard University researching neural networks in the living brain, Marvin Minsky created the confocal microscope (Minsky, 1988). Minsky patented the idea of confocal imaging in 1957, which involves…
Flagella stain principle Flagella are intricate filamentous cytoplasmic structures that protrude through the cell wall. The flagellin protein, which makes up the majority of these unbranched, lengthy, thread-like filaments, is delicately woven into the cell membrane. They are roughly…
Principle of capsule staining Definition The glycocalyx is the name for a polysaccharide or polypeptide layer that is gelatinous. These polysaccharides are found outside the bacterial cell wall and can be heteropolysaccharides or homopolysaccharides made up of different types…
Endospore staining history In 1922, Dorner published a set of staining instructions. He discovered a method of differential labeling called endospore stain that makes vegetative cells seem pinkish-red and endospores appear green under the light microscope. Dorner’s method included…
The first stage in the majority of staining procedures is often smear preparation, which is a basic skill in the microbiology lab. The ensuing staining process will be directly impacted by the quality of the smear. Depending on the material…
Gram staining is a differential bacterial staining method used to distinguish between Gram Positive and Gram Negative bacteria based on the makeup of their cell walls. There are many different types of staining the most important one is gram staining. It…
What is the staining technique? Staining in microbiology involves adding dyes to the smear that are either charged-attractive (cationic dyes like methylene blue or crystal violet) or charged-repelling (anionic dyes like eosin or India ink). Bacterial cells are bound…
What is the Bacterial growth curve? What are the phases of bacterial growth? Even while comprehending the differences between the lag, log, stationary, and death phases of a cell growth curve despite the fact that it may appear like…
What is Bacterial growth? In a process known as binary fission, bacterial growth occurs when a bacterium divides into two daughter cells. The daughter cells that are produced have the same genetic makeup as the original cell, assuming no…
History of acid fast bacteria Paul Ehrlich was the first to explain the bacterium’s ability to withstand acid quickly. By including phenol (carbolic acid) and basic fuschin, Friedrich Nesslsen and Franz Ziehl improved the stain in the 1890s. Because…
