Structural biology of Gram-positive bacterial adhesins.
The structural biology of Gram-positive cell surface adhesins is an emerging field of research, whereas Gram-negative pilus assembly and anchoring have been extensively investigated and are well understood. Gram-positive surface proteins known as MSCRAMMs (microbial surface components recognizing adhesive matrix molecules) and individual proteins that assemble into long, hair-like organelles kn...

15 صفحه اولInvasion of dentinal tubules by oral bacteria.
Bacterial invasion of dentinal tubules commonly occurs when dentin is exposed following a breach in the integrity of the overlying enamel or cementum. Bacterial products diffuse through the dentinal tubule toward the pulp and evoke inflammatory changes in the pulpo-dentin complex. These may eliminate the bacterial insult and block the route of infection. Unchecked, invasion results in pulpitis ...
متن کاملColonization of the cementum surface of teeth by oral Gram-negative bacteria.
By using in vitro assays, a group of related, filamentous gram-negative bacteria isolated from subgingival plaque deposits of patients with periodontal disease were found to colonize intact teeth. Tentatively identified as members of the genus Cytophaga, these isolates exhibited a preference for colonizing the cementum surface of the root. Examination of intact teeth after several weeks of colo...
متن کاملSurface adhesins and exopolymers of selected foodborne pathogens.
The ability of bacteria to bind different compounds and to adhere to biotic and abiotic surfaces provides them with a range of advantages, such as colonization of various tissues, internalization, avoidance of an immune response, and survival and persistence in the environment. A variety of bacterial surface structures are involved in this process and these promote bacterial adhesion in a more ...
