Brain abscess due to Streptococcus oralis in an immunocompetent patient

Indian Journal of Medical Microbiology, 2014
A bacteriologically proven case of brain abscess, due to Streptococcus oralis is being reported in a 12-year-old girl who is a known case of congenital heart disease. The patient presented with fever, headache and vomiting. Pus cultures yielded S. oralis.

Streptococcus oralis previously identified as uncommon ‘Streptococcus sanguis’ in Behçet's disease

Archives of Oral Biology, 1995
The relation between the biochemical and serological properties of 'Streptococcus sanguis' was studied to characterize the strains isolated from dental plaque of patients with Behçet's disease and controls. Seven reference and 100 clinical strains preserved by the Behçet's Disease Research Committee of Japan were identified using established criteria ...

A rare complication of dental treatment: Streptococcus oralis meningitis

British Dental Journal, 1993
A case of Streptococcus oralis meningitis is reported. This followed extraction of a normal tooth during routine orthodontic treatment. No focus of infection could be demonstrated, either local to or distant from the extraction site. Full recovery followed hospital admission and intravenous benzyl penicillin.

Extracellular dextranase from Streptococcus oralis.

Microbios, 1993
A human dental plaque organism, Streptococcus oralis (S. mitior), was cultivated in a dextran-free, dialysed medium, and dextranase activity was isolated from the cell-free, culture supernatant. The lyophilized, crude enzyme preparation, optimum pH 6, was subjected sequentially to anion exchange and gel filtration fast protein liquid chromatography ...

Méningite à Streptococcus oralis après myélographie

Médecine et Maladies Infectieuses, 1998
Summary Bacterial meningitis is a rare complication of myelography. Viridans streptococci are responsible in must cases. The authors described a new case of meningitis due to Streptococcus oralis occurring more than 3 days after myelography in a 55 year old woman. The probable origin and the mechanism of infection are discussed.

The smiting of Streptococcus mitis and Streptococcus oralis: A novel antimicrobial proposition

Asia Pacific Journal of Molecular Biology and Biotechnology
S. mitis and S. oralis are typically found in the oral cavity of humans, but they have the potential to become harmful pathogens that cause infective endocarditis and bacteraemia, especially in individuals with weakened immune systems. Antimicrobial resistance (AMR) in bacteria is a serious issue that poses a significant threat to public health, and if

Identification and characterization of a protease from Streptococcus oralis C104

Oral Microbiology and Immunology, 1996
Streptococcus oralis is among the earliest colonizers of the tooth surface during plaque formation. As such, its enzymatic activities may influence ecologic succession on the tooth surface. In the current study, we used zymograms and preparative polyacrylamide gel electrophoresis to identify and purify a protease from S.

The antibacterial properties of solid supported liposomes on Streptococcus oralis biofilms

International Journal of Pharmaceutics, 2003
A novel system for the delivery of drugs to bacterial biofilms has been developed. The system is based on the use of anionic and cationic liposomes as drug carriers adsorbed on the surface of zinc citrate particles. The adsorption process results in the formation of solid supported vesicles (SSVs) which aids the stabilisation of the liposomes.
