Studies on corynebacterial precipitinogens common to Mycobacteria, Nocardiae and rhodochrous. 1977

M Ridell

Ten strains of Corynebacterium were analyzed by means of the comparative immunodiffusion technique employing reference precipitation systems from strains of Mycobacterium, Nocardia and the rhodochrous taxon. The test strains had precipitinogens in common with the reference strains. Two of the intergenerical cross-reacting precipitinogens revealed were labelled x and y. Two other precipitinogens (alpha,beta), earlier found to be common for strains of mycobacteria, nocardiae, and rhodochrous, were not demonstrated in the corynebacterial strains, thus indicating a qualitative or quantitative serological difference between Corynebacterium and the other taxa. It was furthermore shown that the corynebacterial preparations reacted with antisera against ribosomal 30S fractions from mycobacteria. Common precipitinogens in ribosomal preparations from mycobacteria, nocardiae, rhodochrous, and corynebacteria are discussed.

UI	MeSH Term	Description	Entries
D009161	Mycobacterium	A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts.	Mycobacteria
D009162	Mycobacterium avium	A bacterium causing tuberculosis in domestic fowl and other birds. In pigs, it may cause localized and sometimes disseminated disease. The organism occurs occasionally in sheep and cattle. It should be distinguished from the M. avium complex, which infects primarily humans.
D009163	Mycobacterium bovis	The bovine variety of the tubercle bacillus. It is called also Mycobacterium tuberculosis var. bovis.	BCG,Calmette-Guerin Bacillus
D009615	Nocardia	A genus of gram-positive, aerobic bacteria whose species are widely distributed and are abundant in soil. Some strains are pathogenic opportunists for humans and animals.	Micropolyspora
D009616	Nocardia asteroides	A species of bacterium of the family NOCARDIACEAE, producing pulmonary infections in man.
D011232	Chemical Precipitation	The formation of a solid in a solution as a result of a chemical reaction or the aggregation of soluble substances into complexes large enough to fall out of solution.	Precipitation, Chemical
D003352	Corynebacterium	A genus of asporogenous bacteria that is widely distributed in nature. Its organisms appear as straight to slightly curved rods and are known to be human and animal parasites and pathogens.
D005779	Immunodiffusion	Technique involving the diffusion of antigen or antibody through a semisolid medium, usually agar or agarose gel, with the result being a precipitin reaction.	Gel Diffusion Tests,Diffusion Test, Gel,Diffusion Tests, Gel,Gel Diffusion Test,Immunodiffusions,Test, Gel Diffusion,Tests, Gel Diffusion
D000941	Antigens	Substances that are recognized by the immune system and induce an immune reaction.	Antigen
D001500	BCG Vaccine	An active immunizing agent and a viable avirulent attenuated strain of MYCOBACTERIUM BOVIS, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.
