Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
Antibodies against Salmonella and other bacteria, as well as against viruses, are produced in this manner, and employed as a nutritional component for protection against these pathogens. The Food Safety Lab of Ocean University of China has experimented with using IgY specific to the bacteria Shewanella putrefaciens and Pseudomonas fluorescens ...
[3] [4] Neutralizing antibodies are part of the humoral response of the adaptive immune system against viruses, bacteria and microbial toxin. By binding specifically to surface structures ( antigen ) on an infectious particle, neutralizing antibodies prevent the particle from interacting with its host cells it might infect and destroy.
Scheme of the complement system. The complement system, also known as complement cascade, is a part of the humoral, innate immune system and enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.

The mucous membranes are in constant contact with microorganisms, food, and inhaled antigens. [2] In healthy states , the mucosal immune system protects the organism against infectious pathogens and maintains a tolerance towards non-harmful commensal microbes and benign environmental substances.

Hapten-specific antibodies are used in broad area of different immunoassays, immunobiosensor technologies and immunoaffinity chromatography purification columns; those antibodies could be used to detect small environmental contaminants, drugs of abuse, vitamins, hormones, metabolites, food toxins and environmental pollutants.
Again, antibiotics only work against bacterial infections. “It does not work against viruses or fungus,” says Tran. “The confusion always comes up around wintertime because of the flu.
An immune response is a physiological reaction which occurs within an organism in the context of inflammation for the purpose of defending against exogenous factors. These include a wide variety of different toxins, viruses, intra- and extracellular bacteria, protozoa, helminths, and fungi which could cause serious problems to the health of the host organism if not cleared from the body.
