Characterization of immunoglobulin G‐degrading proteases of Prevotella intermedia and Prevotella nigrescens [PDF]
Oral Microbiology and Immunology, 1995 Degradation of immunoglobulins is thought to be an important factor in the causation of periodontal diseases by hindering local host defenses and by providing nutrients to the periodontal microflora. In this study, we characterized the proteolytic activity against human immunoglobulin G (IgG) of 20 strains of Prevotella intermedia and Prevotella ...

Frequency of putative periodontal pathogens among type 1 diabetes mellitus: a case–control study
BMC Research Notes, 2019 Objective The aim of the present study is to compare and assess the risk of periodontitis due to the presence of four putative periodontopathic bacteria viz., Eikenella corrodens, Campylobacter rectus, Prevotella intermedia and Prevotella nigrescens.

Incidence of Prevotella intermedia and Prevotella nigrescens in Periodontal Health and Disease [PDF]
Microbiology and Immunology, 1998 AbstractThe incidence of black‐pigmented rods (BPRs), especially Prevotella intermedia and Prevotella nigrescens, in periodontal health and disease were examined. Furthermore, the degradative enzyme activities of P. intermedia were compared among the strains from periodontal health and disease.

Species-specificity of monoclonal antibodies recognising Prevotella intermedia and Prevotella nigrescens [PDF]
FEMS Microbiology Letters, 1994 Prevotella intermedia and Prevotella nigrescens are not easily distinguished, making it difficult to assess their roles in disease. This study examined the specificity of three monoclonal antibodies (mAbs) for these species. Differentiation between P. intermedia (13 isolates) and P.

Intraspecies Variability Affects Heterotypic Biofilms of Porphyromonas gingivalis and Prevotella intermedia: Evidences of Strain-Dependence Biofilm Modulation by Physical Contact and by Released Soluble Factors. [PDF]
PLoS ONE, 2015 It is well known that strain and virulence diversity exist within the population structure of Porphyromonas gingivalis. In the present study we investigate intra- and inter-species variability in biofilm formation of Porphyromonas gingivalis and partners

Prevotella intermediaandPrevotella nigrescensserotypes, ribotypes and binding characteristics [PDF]
FEMS Microbiology Letters, 1996 Type strains and 62 clinical isolates of Prevotella intermedia and Prevotella nigrescens were typed with the use of genomic DNA fingerprints and rRNA gene probes. The strains were further serotyped with monoclonal antibodies and characterized with SDS-PAGE, enzymatic activities, hemolysis and hemagglutination and coaggregation with Streptococcus and ...

Binding and Utilization of Human Transferrin by Prevotella nigrescens [PDF]
Infection and Immunity, 1999 ABSTRACT To survive and multiply within their hosts, pathogens must possess efficient iron-scavenging mechanisms. In the present study, we investigate the capacity of Prevotella nigrescens and Prevotella intermedia to use various sources of iron for growth and characterize the ...
