Bacteriology is the study of bacteria, which are single-celled microorganisms that can be found almost anywhere on Earth. Bacteria are some of the most ancient and diverse forms of life, and they play important roles in many different environments, including the human body.
Bacteriology is a subfield of microbiology, which is the study of all microorganisms, including bacteria, viruses, fungi, and protists. Bacteriology focuses specifically on the biology, genetics, and evolution of bacteria, as well as their role in various ecological and medical contexts.
Bacteriologists use a variety of techniques and tools to study bacteria, including microscopy, cultivation and growth techniques, and molecular techniques such as DNA sequencing. They may also use animal models or human subjects to study the effects of bacteria on health and disease.
Overall, bacteriology is an important field of study that helps us understand the diversity and roles of bacteria in the world, as well as the ways in which they can affect human health and the environment.
Structure and Composition of Lipopolysaccharide (LPS) It is composed of three components like; O-antigen Core Structure of Core or Core oligosaccharide (or Core-OS) The core domain always contains an oligosaccharide component which attaches directly to lipid A and commonly contains sugars such as heptose and 3-deoxy-D-mannooctulosonic acid (also known as KDO or keto-deoxyoctulosonate). It is … Read more
What is Sphaeroplast? A Spheroplast (or sphaeroplast according to British use) can be described as a microbe organism with a cell wall that is almost entirely gone through the penicillin or Lysozyme. According to certain definitions the term is employed to refer to Gram-negative bacteria. In other definitions, the word also includes yeasts. Spheroplast’s name … Read more
Protoplast Definition Protoplasts are plant cells that are completely naked with no cell wall however they do have plasma membranes and other components of the cell. They are functional cells, but without the presence of a barrier, cell wall. Protoplasts from various species can be merged to create a hybrid, and this is known as … Read more
The protoplast, sometimes referred to as a naked plant cell refers to all the constituents in a cell of plant that are not the wall of the cell. The term”protoplast” was first used in the work of Hanstein in 1880 to refer to the living matter contained within the membrane of the plant cell. The … Read more
The process of somatic fusion is also known as protoplast Fusion, is a kind of genetic modification of plants in which two plant species are merged into a hybrid plant that has the traits of both species the species, an somatic hybrid. Hybrids are created among different species that are of the exact same species … Read more
Isolated protoplasts can be cultured in a liquid medium , or semisolid agar medium , either in thin layers or tiny drops of nutrient medium in petridish. The medium used to cultivate protoplasts is the same as that needed for suspension or callus culture. The increase in calcium concentration aids in maintaining the membrane’s integrity. … Read more
Microbiological cultures, also known as Microbial culture is the technique of generating microbial species by the process of letting them reproduce in a conditions in a monitored laboratory conditions. Microbiological cultures are fundamental and essential diagnostic methods that are employed as research tools within molecular biology. The term “culture” could be used to describe the … Read more
Antimicrobial Susceptibility Testing (AST) Techniques of Antimicrobial Susceptibility test Antimicrobial susceptibility tests in the laboratory can be done by using: Dilution susceptibility tests Disc diffusion susceptibility tests Kirby-Bauer NCCLS modified disc diffusion technique Stokes disc diffusion technique Disadvantages of antimicrobial susceptibility tests Susceptibility tests determine the antimicrobial effect against bacteria in conditions of laboratory (in … Read more
The most commonly used gram-negative cocci of medical significance fall under the category of Neisseriaceae which comprises the genera Neisseria, Moraxella, Kingella, Acinetobacter etc. Medical Significance of Gram Negative Cocci Neisseria species The genus Neisseria contains 12 species, two of which, N.meningitidis and N. gonorrhoeae, are commonly pathogenic in humans. Both may cause infections in … Read more
Chemosynthesis involves the conversion of carbon compounds as well as others molecules to organic substances. In this biochemical process, methane, or an inorganic compound like hydrogen sulfide or gas, is converted into a form that can serve as an energy source. However, the photosynthesis process’s energy source (the series of reactions in which water and … Read more
