Candidiasis- Opportunistic Mycoses

Candidiasis- Opportunistic Mycoses

Candidiasis- Opportunistic Mycoses Opportunistic mycoses refer to the infections caused by fungi in hosts with immune-compromised conditions. The fungi involved in the infection are called as opportunistic fungi. The reasons behind this incidence include the overuse of antibiotics, corticosteroids, and immunosuppressive drugs. Candidiasis is an infection of the skin, mucosa, and internal …

Virus Classification on the basis of morphology and replication

Virus Classification on the basis of morphology and replication

Virus Classification on the basis of morphology and replication Viruses are a specific group of microorganisms that can replicate only inside of a cell. These are extremely small organisms and visible only under an electron microscope. Viral infections can occur in all types of life forms including plants, animals and other microorganisms …

Design of a Fermenter

Design of a Fermenter

Design of a Fermenter Fermenter or bioreactor refers to a device that provides all the basic necessities important for biological product extraction. A fermenter contains different devices that help to maintain the environmental factor inside it which in turn leads to the production of biological products. Therefore the main objective of a …

Environmental Factors affecting Microbial Growth

Environmental Factors affecting Microbial Growth

Environmental Factors affecting Microbial Growth Apart from nutritional components growth of the microbes are also dependent on several environmental factors. These factors play an important role in understanding the growth pattern of a microbe. Apart from that, it is important to understand these factors especially in an industrial set up where a …

Sterilization- physical and chemical methods

Sterilization- physical and chemical methods

Microorganisms play an important role in causing infection and contamination. Therefore, Sterilization is an important technique in microbiology which helps to remove or destroy microorganisms from materials or surfaces. Common Definitions Sterilization It is the process by which an article, surface or medium is made free of all microorganisms either in vegetative …

Solute Transport Mechanisms in Bacteria

Solute Transport Mechanisms in Bacteria

Bacteria require several nutrients for their growth. Structural components such as cell wall and cell membrane restrict the entry of several molecules inside the cell. Therefore, the specific mechanism for nutrient uptake is highly important for the bacterial cell. Image Source: Dr. Kenneth Todar There are different transport mechanisms involved in the …

Cell Inclusion Bodies

Cell inclusion Bodies

Cell inclusion Bodies Bacterial cell inclusion bodies are otherwise known as granules. Electron microscopic observation reported the presence of both organic and inorganic granules inside the bacterial cell. These granules function as energy storage and these are also involved in reducing osmotic pressure. Some of these granules are found freely moving in …

Immunological Techniques

Immunological Techniques

Immunological Techniques Most of the immunological techniques are based upon the antigen-antibody reactions. Precipitation reactions are one of the important reactions that occur when antigen and antibody come to contact. When a soluble antigen reacts with its antibody in the presence of NaCl at optimal temperature and pH, the antigen-antibody complex forms …
