The key difference between granular and agranular leukocytes is that granular leukocytes have granules in their cytoplasm, but agranular leukocytes lack granules in the cytoplasm. Leukocytes or white blood cells are one of the main types of blood cells. They are spherical in shape and colourless compared to red blood cells. The number of WBCs […]

The key difference between alloantibody and autoantibody is that the alloantibody is an antibody produced against alloantigens, which are foreign antigens introduced by transfusion or pregnancy. Meanwhile, the autoantibody is an antibody that reacts with self-antigens. Antibodies are produced as a result of an immune response. They may reflect the presence, nature and intensity of […]

The key difference between phagocytosis and opsonization is that phagocytosis is a mechanism executed by certain cells or organisms to ingest or engulf foreign particles while opsonization is the process by which pathogens are removed from the system upon being marked by means of opsonins. Immunologic responses can be innate or adaptive. Pathogens possess pathogen […]

The key difference between cell mediated and antibody mediated immunity is that cell mediated immunity destroys infectious particles via cell lysis by cytokines, without the production of antibodies, while antibody mediated immunity destroy pathogens by producing specific antibodies against antigens. Cell mediated immunity and antibody mediated immunity are two types of primary defence mechanisms taking […]

The key difference between immunosuppression and immunodeficiency is that immunosuppression refers to the reduction of the efficiency of the immune system, while immunodeficiency refers to the inability of the immune system to fight against infectious agents. The immune system detects a wide array of infectious agents entering our body and protects us from diseases. Therefore, […]

The key difference between polymorphonuclear and mononuclear cells is that polymorphonuclear cells have a nucleus with several lobes while mononuclear cells have a round nucleus which has only one lobe. Blood consists of three major types of blood cells: erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets). Leukocytes are the main cells […]

The key difference between bivalent and trivalent polio vaccine is that bivalent polio vaccine contains only type 1 and type 3 serotypes of poliovirus while trivalent vaccine contains all three serotypes. Poliovirus exists as three serotypes. All three serotypes are able to cause poliomyelitis. Vaccination is the most effective way of preventing polio disease. Among […]

The key difference between Salk and Sabin polio vaccine is that Salk polio vaccine, which was the first effective polio vaccine, is an inactivated vaccine while Sabin polio vaccine is a live but an attenuated oral vaccine developed after Salk vaccine. Polio or poliomyelitis is an infectious disease caused by the poliovirus. The infection causes […]

The key difference between DNA vaccine and recombinant vaccine relies on the preparation of vaccines. DNA vaccine preparation takes place using desired genes or DNA fragments, while recombinant vaccine preparation takes place using a recombinant molecule or a vector containing the desired gene fragment. Vaccinations can be used as prophylactic treatment methods as well as […]

The key difference between variolation and vaccination is the method of immunization. Variolation involves administering live viruses to develop immunity of the host while vaccination involves administering an attenuated virus in response to an infection. Immunization acts as both a prophylactic and a therapeutic method for infection prevention and treatment. There are different methods of […]
