Effect of mucin and glucose on proteolytic and glycosidic activities of Streptococcus oralis [PDF]

open access: bronzeJournal of Medical Microbiology, 1996
The production of glycosidase and protease activities, which may play a role in the degradation of human glycoproteins, by Streptococcus oralis strains isolated from endocarditis, septicaemia or the oral cavity was investigated with a range of fluorogenic substrates.

Forward Genetic Dissection of Biofilm Development by Fusobacterium nucleatum: Novel Functions of Cell Division Proteins FtsX and EnvC. [PDF]

open access: yes, 2018
Fusobacterium nucleatum is a key member of the human oral biofilm. It is also implicated in preterm birth and colorectal cancer. To facilitate basic studies of fusobacterial virulence, we describe here a versatile transposon mutagenesis procedure and a ...

Antibody binding to Streptococcus mitis and Streptococcus oralis cell fractions [PDF]

open access: yesArchives of Oral Biology, 2008
To determine which cell fraction(s) of Streptococcus mitis biovar 1 serve as the best source of antigens recognized by salivary SIgA antibodies in infants.Whole cells of 38 reference and wild-type isolates of S. mitis, Streptococcus oralis, Streptococcus gordonii, Enterococcus casseliflavus, and Enterococcus faecalis were fractionated into cell walls ...

Defining antibody targets in Streptococcus oralis infection [PDF]

open access: yesInfection and Immunity, 1996
Immunoblotting of sera from 12 neutropenic patients with Streptococcus oralis septicemia and 18 patients with endocarditis due to viridans group streptococci revealed immunodominant S. oralis antigens at 85 and 180 kDa. The former cross-reacted with a mouse monoclonal antibody to hsp90.

Detection and expression analysis of tet(B) in Streptococcus oralis. [PDF]

open access: yesJ Oral Microbiol, 2019
Tetracycline resistance can be achieved through tet genes, which code for efflux pumps, ribosomal protection proteins and inactivation enzymes. Some of these genes have only been described in either Gram-positive or Gram-negative bacteria. This is the case of tet(B), which codes for an efflux pump and, so far, had only been found in Gram-negative ...

Infection of Streptococcus oralis NCTC 11427 by pneumococcal phages [PDF]

open access: yesFEMS Microbiology Letters, 1989
We have found a group of pneumococcal bacteriophages (Cp-1, Cp-7) that can successfully infect and replicate in Streptococcus oralis, whereas Dp-1 was unable to infect this species. We have also developed conditions that allowed transfection of S. oralis using Dp-1 DNA.

Evaluation of the Antimicrobial Effect of Thymoquinone against Different Dental Pathogens: An In Vitro Study

open access: yesMolecules, 2021
This study aimed to evaluate the antimicrobial effect of Thymoquinone (TQ) on four different oral microorganisms. Minimum Bactericidal Concentration (MBC), Minimum Inhibition Concentration (MIC), Broth microdilution, and Well diffusion tests were used to
