A murC gene in Porphyromonas gingivalis 381.
The gene encoding a 51 kDa polypeptide of Porphyromonas gingivalis 381 was isolated by immunoblotting using an antiserum raised against P. gingivalis alkaline phosphatase. DNA sequence analysis of a 2.5 kb DNA fragment containing a gene encoding the 51 kDa protein revealed one complete and two incomplete ORFs. Database searches using the FASTA program revealed significant homology between the P...
متن کاملThe hemagglutinin gene A (hagA) of Porphyromonas gingivalis 381 contains four large, contiguous, direct repeats.
Porphyromonas gingivalis is a gram-negative anaerobic bacterial species strongly associated with adult periodontitis. One of its distinguishing characteristics and putative virulence properties is the ability to agglutinate erythrocytes. We have previously reported the cloning of multiple hemagglutinin genes from P. gingivalis 381. Subsequent sequencing of clone ST 2 revealed that the cloned fr...
متن کاملPurification and characterization of a novel secondary fimbrial protein from Porphyromonas gingivalis strain 381.
We previously reported the existence of two different kinds of fimbriae expressed by Porphyromonas gingivalis ATCC 33277. In this study, we isolated and characterized a secondary fimbrial protein from strain FPG41, a fimA-inactivated mutant of P. gingivalis 381. FPG41 was constructed by a homologous recombination technique using a mobilizable suicide vector, and failed to express the long fimbr...
متن کاملPorphyromonas gingivalis
Editorial Periodontal diseases have long been associated with an increased, yet moderate, risk for the development of atherosclerosis and coronary heart disease. The postulated mechanism underlying this association is the low grade systemic inflammatory response to pathogens engaged in chronic periodontal infection, such as Porphyromonas gingivalis, which may facilitate atheroma formation and t...
متن کاملHumoral immune response to an antigen from Porphyromonas gingivalis 381 in periodontal disease.
The humoral immune responses of patients with periodontitis were evaluated to characterize the host response to Porphyromonas gingivalis. A sonic extract of P. gingivalis 381 from whole cells was fractionated by gel chromatography and ion-exchange chromatography. The fractionated extracts were evaluated by Western blot (immunoblot) analyses with patient sera. A dominant antigen was identified f...
