Toxic properties of the cell wall of gram-positive bacteria.
The biological activity of Odontomyces viscosus, which has been reported to cause periodontal disease in hamsters, was examined. The microorganism was cultured anaerobically in Brain Heart Infusion broth, and the cells were harvested. The washed cells were injected intradermally into the abdomen of rabbits. After 72 hr, a well-defined, firm, raised nodule (about 1.0 by 1.5 cm) with an erythemat...
متن کاملInfluence of decontamination on induction of arthritis in Lewis rats by cell wall fragments of Eubacterium aerofaciens. Arthropathic properties of indigenous anaerobic bacteria.
Although the cause (or causes) of rheumatoid arthritis is unknown, many workers have suggested that microorganisms play a part. The intestinal flora in particular has been related to the development of joint inflammation. It has been shown previously that cell wall fragments of several anaerobic Gram positive intestinal bacteria of human origin are arthritogenic after a single intraperitoneal i...
متن کاملTrans-membrane synthesis of cell wall polymers.
outer surface, similar protrusion inwards might be expected with isolated walls, whereas a difference in the gel structure of the wall could explain the morphological difference, and also the finding (Burger, 1966) that isolated walls bind little more antibody than do whole bacteria. The inacessibility of new teichoic acid to concanavalin A at the bacterial surface shows that the teichoic acid ...
متن کاملRevised mechanism of d-alanine incorporation into cell wall polymers in Gram-positive bacteria
Teichoic acids (TAs) are important for growth, biofilm formation, adhesion and virulence of Gram-positive bacterial pathogens. The chemical structures of the TAs vary between bacteria, though they typically consist of zwitterionic polymers that are anchored to either the peptidoglycan layer as in the case of wall teichoic acid (WTA) or the cell membrane and named lipoteichoic acid (LTA). The po...
متن کاملCell wall analysis of oral filamentous bacteria.
The cell wall compositions of 41 strains of oral filamentous bacteria belonging to the genera Fusobacterium, Leptotrichia and Bacterionema were examined by paper chromatography. Leptotrichia walls showed principally alanine, glutamic acid, DAP, glycine and aspartic acid. The genus Bacterionema had the same amino acids but aspartic acid appeared to be a minor component and was not detected in th...
