In Vitro Effects of Streptococcus oralis Biofilm on Peri-Implant Soft Tissue Cells [PDF]

Cells, 2020
Human gingival epithelial cells (HGEps) and fibroblasts (HGFs) are the main cell types in peri-implant soft tissue. HGEps are constantly exposed to bacteria, but HGFs are protected by connective tissue as long as the mucosa–implant seal is intact ...

Highly Variable Streptococcus oralis Strains Are Common among Viridans Streptococci Isolated from Primates

MSphere, 2016
Viridans streptococci were obtained from primates (great apes, rhesus monkeys, and ring-tailed lemurs) held in captivity, as well as from free-living animals (chimpanzees and lemurs) for whom contact with humans is highly restricted. Isolates represented

Low penicillin susceptibility in Streptococcus mitis/oralis from bloodstream infections in pediatric populations

Microbiology Spectrum
Streptococcus mitis/oralis can cause invasive diseases, including bloodstream infections. However, existing research primarily focuses on specific populations, and limited studies have been conducted on the prevalence of bloodstream infection caused by S.

Glycoprotein Ibα and FcγRIIa play key roles in platelet activation by the colonizing bacterium, Streptococcus oralis

Journal of Thrombosis and Haemostasis, 2013
Background: Infective endocarditis (IE) is characterized by thrombus formation on a cardiac valve. The oral bacterium, Streptococcus oralis, is recognized for its ability to colonize damaged heart valves and is frequently isolated from patients with IE ...

Metabolic changes associated with adaptive resistance to daptomycin in Streptococcus mitis-oralis

BMC Microbiology, 2020
Background Viridans group streptococci of the Streptococcus mitis-oralis subgroup are important endovascular pathogens. They can rapidly develop high-level and durable non-susceptibility to daptomycin both in vitro and in vivo upon exposure to daptomycin.

Complete Genome Sequence of Streptococcus oralis 34. [PDF]

Microbiol Resour Announc, 2021
Streptococcus oralis is an early colonizer and one of the most abundant species found in the human oral cavity. We report the complete genome sequence of S. oralis 34 (1,920,884 bp; GC content, 41.3%), commonly used in many oral microbiology studies exploring bacterial attachment and interaction(s ...

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.
