Induction of stable L-forms of Salmonella typhi and Listeria monocytogenes. 1985

P J Asnani, and K Gill

Stable L-forms of Salmonella typhi and Listeria monocytogenes were produced using penicillin (4500 units/ml) as inducer, and sucrose, normal horse serum and Mg++ as stabilizers. Stable L-forms were produced after 100 and 56 passages, then adapted to grow and multiply in a medium free of inducer and stabilizers so that they did not revert to parental forms even after 12 continuous passages.

UI	MeSH Term	Description	Entries
D007740	L Forms	Bacterial variants, unable to form a complete cell wall, which are formed in cultures by various bacteria; granules (L bodies) appear, unite, and grow into amorphous bodies which multiply and give rise to bacterial cells morphologically indistinguishable from the parent strain.
D008089	Listeria monocytogenes	A species of gram-positive, rod-shaped bacteria widely distributed in nature. It has been isolated from sewage, soil, silage, and from feces of healthy animals and man. Infection with this bacterium leads to encephalitis, meningitis, endocarditis, and abortion.
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D010406	Penicillins	A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.

D012485	Salmonella typhi	A serotype of SALMONELLA ENTERICA which is the etiologic agent of TYPHOID FEVER.	Salmonella enterica serovar Typhi,Salmonella typhosa
D013395	Sucrose	A nonreducing disaccharide composed of GLUCOSE and FRUCTOSE linked via their anomeric carbons. It is obtained commercially from SUGARCANE, sugar beet (BETA VULGARIS), and other plants and used extensively as a food and a sweetener.	Saccharose
