HAEMOCYTOMETER CELL COUNT FOR CSF SAMPLE

DrChika

Cells of mammalian or prokaryotic or eukaryotic cells can be counted in the lab from samples using different kinds of counting chmabers. The neubauer counting chamber is one major type of counting chamber generally used for counting cells, manually in the microbiology laboratory. Improved neubauer counting chamber is a manual chamber or haemocytometer that allows […]

TYPES OF METABOLISM

DrChika

Metabolic reactions help to maintain a state of balance or equilibrium in the cell. And the energy released during these processes is used by the cell for growth and other cellular activities. The growth of microorganisms requires the polymerization of building blocks (e.g. amino acids and nucleotides) into proteins, lipids, carbohydrates and nucleic acids. These

METABOLISM

DrChika

Metabolismis simply defined as the summation of the chemical reactions that occurs in the cell at each point in time. It is the processes of catabolism (i.e. breaking down of molecules) and anabolism (i.e. the building up of newer molecules) that occur in the cell. Metabolism is critical for the management of an organism’s energy

PROBIOTICS

DrChika

According to the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO), the term “probiotics” refers to live microorganisms (especially bacteria and fungi) that when administered in adequate amounts confer health benefits to the host taking it. The intestinal microbiota is important for the maintenance of good health in

CELL IMMOBILIZATION

DrChika

Cell immobilizationis the process of fixing the cells of living organisms including plants, animals, enzymes and microbial cells in a suitable matrix capable of holding them in place. The term “immobilization” is generally used to describe the technique of attaching cells to surfaces either by entrapment or by particle attachment. And the cell immobilization

INNATE IMMUNITY

DrChika

Innate immunity is the body’s natural inborn resistance to infection and it is quick in responding to invasive microbes. It is a component of the immune system that is an inherited protective mechanism, and which protect the body of an animals from many kinds of pathogens. Innate immunity is a nonspecific immune response to antigens,

SIGNIFICANCE OF MONOCLONAL AND POLYCLONAL ANTIBODIES

DrChika

The two basic forms in which antibodies can be produced in purified forms in the laboratory are as monoclonal antibodies and polyclonal antibodies. Monoclonal antibodies are homogenous antibodies produced in the laboratory by a single clone of cells (known as hybridoma cells), and all of which exhibit the same antigenic specificity. Hybridomas are cells capable

ORGANS OF THE IMMUNE SYSTEM AND THEIR FUNCTION

DrChika

The organs of the immune system are generally divided into two major groups which are the primary lymphoid organs and the secondary lymphoid organs. The bone marrow, spleen, thymus, Peyer’s patches, liver, the tonsils, the lymph nodes and several mucosal-associated lymphoid tissues (MALT) are some of the major organs or tissues that makeup the immune

B CELL PRODUCTION

DrChika

B cells are specialized type of lymphocytes that are responsible for the production of antibodies or immunoglobulins that act as effector molecules to stimulate the entire immune system against an invading antigen or pathogen. They are primarily responsible for the development of antibody mediated immunity (AMI) in the body; and B cells are produced in
