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 […]

The key difference between opsonization and neutralization relies on the way they perform the immunological response. In opsonization, the pathogens are marked prior to being destroyed while in neutralization, the effect of the pathogen is neutralized. Immunologic responses can be innate or adaptive. Pathogens possess pathogen recognition receptors, which make it easier to be identified […]

The key difference between antiserum and antibody is that antiserum is blood serum that is rich in specific antibodies against an infective organism or a poisonous substance, while antibody is an immunoglobulin protein that identifies and binds with foreign antigens that enter into our bloodstream. Antibodies play a major role in our immune system by […]

The key difference between serum and antiserum is that serum is the straw coloured fluid component of blood without blood cells and clotting factors, while antiserum is antibody-rich serum obtained from an immunized animal or human. Blood is a specialized body fluid that circulates throughout our body, delivering essential substances such as oxygen and nutrients […]

The key difference between central and peripheral tolerance is that thymus and bone marrow are the places that induce the state of central tolerance while lymph nodes and other tissues are the places that induce the state of peripheral tolerance. Immune tolerance is a state of unresponsiveness of the immune system to substances or tissues […]

The key difference between microphage and macrophage is that the microphage is a type of small phagocyte living only for a few days while the macrophage is a type of larger phagocyte with a longer life. Our immune system fights with invading pathogenic microorganisms and keeps us safe. Hence, it is a complex system that executes […]
