Demonstration of shared antigens in the genus Clostridium by an enzyme-linked immunosorbent assay. 1984

I R Poxton, and M D Byrne

Antigens prepared from several strains of each of 10 Clostridium species were used in an indirect enzyme-linked immunosorbent assay with antisera raised against whole cells of a representative strain from each of the 10 species killed by ultra-violet irradiation. With the exception of C. cadaveris, the antisera gave similar results with antigens prepared from all strains of the homologous species. Antigens prepared from 13 other clostridial species were then investigated in an ELISA system with the 10 representative antisera. The results showed many cross-reactions, particularly in the C. perfringens group, the C. difficile/sordelli group and the C. botulinum/novyi/sporogenes group.

UI	MeSH Term	Description	Entries
D003013	Clostridium	A genus of motile or nonmotile gram-positive bacteria of the family Clostridiaceae. Many species have been identified with some being pathogenic. They occur in water, soil, and in the intestinal tract of humans and lower animals.
D003014	Clostridium botulinum	A species of anaerobic, gram-positive, rod-shaped bacteria in the family Clostridiaceae that produces proteins with characteristic neurotoxicity. It is the etiologic agent of BOTULISM in humans, wild fowl, HORSES; and CATTLE. Seven subtypes (sometimes called antigenic types, or strains) exist, each producing a different botulinum toxin (BOTULINUM TOXINS). The organism and its spores are widely distributed in nature.
D003016	Clostridium perfringens	The most common etiologic agent of GAS GANGRENE. It is differentiable into several distinct types based on the distribution of twelve different toxins.	Clostridium welchii
D003429	Cross Reactions	Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen.	Cross Reaction,Reaction, Cross,Reactions, Cross
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
