Quorum Sensing, types, mechanism and function

Quorum sensing is a way bacteria “talk” to each other by sending out and detecting special chemical signals called autoinducers. This helps them figure out how many other bacteria are nearby. When there are enough of them, they work together and turn on certain genes, especially ones that use a lot of energy, so their

Subunit vaccine, types, use and steps of preparation, limitation

A subunit vaccine is a type of vaccine that contains only specific pieces (or subunits) of a virus or bacteria—usually proteins or sugars—that are enough to trigger an immune response without including the whole pathogen. This makes the vaccine safer and reduces the risk of side effects.

Secondary Metabolites, Types and Medicinal Applications

Secondary metabolites are organic compounds produced by organisms (particularly plants, fungi, and microorganisms) that are not directly involved in their growth, development, or reproduction, but often provide ecological advantages. Many of these compounds have important medicinal applications due to their bioactive properties. Types of secondary metabolites Secondary metabolites can be divided into various types or

Preparation of solid and liquid media for isolation of microorganisms

Microorganisms such as bacteria and fungi require specific nutrients and environmental conditions to grow, which are provided through culture media. Culture media can be liquid (broth) or solid (agar-based). Solid media help in isolating and observing colony morphology, while liquid media are used for growing large volumes of microbial cells or for specific biochemical tests.

Classification of microorganism and taxonomy

Classification of microorganism and taxonomy is one of the important areas in the microbiology field which deals with the classifying organism based on their special characteristics. What are microbes | what is the definition of microbes Importance of Classification and Taxonomy in Microbiology Microorganisms come in many types, and they can look or act very

Isolation, Purification, and Culture Methods of Microbes

Isolation, Purification, and Culture Methods of Microbes is important foundational technique in microbiology. These techniques allow us to study microbes in pure form, essential for diagnostics, research, and industrial applications. Isolation separates a specific microbe from a mixed population; purification ensures the culture is free from contaminants; and culture methods enable the growth and study

Antibody based diagnosis methods, application and limitation

Antibody-based diagnosis refers to diagnostic methods that utilize antibodies to detect the presence of specific pathogens (such as viruses, bacteria, or fungi) or abnormal biomarkers (such as proteins or other molecules) in a patient’s biological samples (e.g., blood, urine, saliva, or tissue). These diagnostic techniques utilize the specific binding capabilities of antibodies to their target
