Synergistic Degradation of Mucin by Streptococcus oralis and Streptococcus sanguis in Mixed Chemostat Cultures

Journal of Dental Research, 1991
Oral streptococci can grow in mucin by utilizing the oligosaccharide chains as a source of carbohydrate. The degradation of the oligosaccharides by these species is accomplished by exoglycosidase activities. In this experiment, it was investigated whether strains from different species could cooperate in the release of sugars from the mucin ...

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 rgg Gene is a Specific Marker for Streptococcus oralis

Journal of Dental Research, 2010
Although the pathogenesis of Streptococcus oralis may be different from that of other viridans group streptococci, S. oralis shares a high degree of DNA sequence similarity with these streptococci. As a result, discrimination of S. oralis from its close relatives has long been considered difficult.

Neonatal meningitis and maternal sepsis caused by Streptococcus oralis

Journal of Neonatal-Perinatal Medicine, 2018
A newborn male infant was admitted to the neonatal unit with suspected early onset neonatal sepsis for monitoring and intravenous antibiotics. Despite his initial normal clinical and laboratory parameters, cerebrospinal fluid cultures done on day 4 of life confirmed Streptococcus oralis meningitis.

Lack of association between Streptococcus oralis and recurrent aphthous stomatitis

Journal of Oral Pathology & Medicine, 2000
Abstract: In the present study, the potential involvement of Streptococcus oralis in the aetiology of recurrent aphthous stomatitis (RAS) was investigated using the polymerase chain reaction (PCR). Biopsies from 28 RAS patients were analysed, in addition to 20 oral lichen planus (OLP) and 13 normal biopsies that were used as controls.

Streptococcus oralis as a Risk Factor for Middle Cerebral Artery Thrombosis

Journal of Child Neurology, 2005
We reported a case of an 8-year-old boy who was presented to the emergency department with left-sided hemiparesis. Computed tomography showed hypodense areas in the territory of the right middle cerebral artery, indicating acute cerebral infarct. Diagnostic evaluation was performed to identify the etiology.
