Genome sequence of the temperate bacteriophage PH10 from Streptococcus oralis [PDF]

, 2018
Exponential growing cultures of Streptococcus oralis strain OMZ 1038, isolated from human supragingival dental plaque, were found to release a bacteriophage (designated PH10) upon treatment with mitomycin C. The complete genome sequence of phage PH10 was

Rifaximin Use Is Associated With Prognosis and Recurrence Patterns in Spontaneous Bacterial Peritonitis: Exploratory Insights Into the Oral–Gut–Hepatic Axis

JGH Open, Volume 10, Issue 4, April 2026.
ABSTRACT Background Spontaneous bacterial peritonitis (SBP) remains a life‐threatening complication in cirrhotic patients with refractory ascites. Evidence for rifaximin (RFX) in SBP prevention and prognosis is lacking in Japan. We investigated the effect of RFX on prognosis and recurrence of SBP and evaluated the prognostic role of oral health within ...

Using Selective Agar Containing Ciprofloxacin and Tetracycline Reveals Resistant Oral Microbiota in Healthy and Periodontitis Patients

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Oral biofilms from healthy and periodontitis patients harbor diverse bacteria, including aerobes and obligate anaerobes. Using selective media with tetracycline or ciprofloxacin, 495 strains (106 species) were isolated. Resistance was common—32.9% to ciprofloxacin, 15.2% to tetracycline, 0.6% to ampicillin—highlighting the oral cavity as a reservoir ...

Antibacterial and cytotoxic properties of endophytic extracts for oral application

Current Directions in Biomedical Engineering
Endophytic fungal extracts possess great potential as alternative antibacterial substances. Here, two extracts from the Australian endemic plant Eremophila longifolia were shown to reduce biomass and metabolic activity of the oral bacteria Streptococcus ...

Inhibitory effect on in vitro Streptococcus oralis biofilm of a soda-lime glass containing silver nanoparticles coating on titanium alloy.

, 2012
This paper reports the effect of soda-lime-glass-nAg coating on the viability of an in vitro biofilm of Streptococcus oralis. Three strains (ATCC 35037 and two clinical isolates from periodontitis patients) were grown on coated with glass, glass ...

Surface fibrils of Streptococcus oralis subsp. dentisani [PDF]

, 2019
Streptococcus oralis is an oral commensal bacterium and a leading cause of sub-acute infective endocarditis (IE). Little is known of the mechanisms by which this bacterium colonizes the oral cavity and causes sub-acute IE.

The rgg Gene is a Specific Marker for Streptococcus oralis

, 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

Purification, Characterization, and Molecular Analysis of the Gene Encoding Glucosyltransferase from Streptococcus oralis

, 2000
Streptococcus oralis is a member of the oral streptococcal family and an early-colonizing microorganism in the oral cavity of humans. S. oralis is known to produce glucosyltransferase (GTase), which synthesizes glucans

Detection and quantification of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Streptococcus oralis in blood samples with different microbiological identification methods: An in vitro study

, 2016
Background: Culture-based methods (culture broth bottles or lysis methods) have been the standard for detecting bacteremia. More recently, quantitative polymerase chain reaction (qPCR) was proposed as a more sensitive and specific test although none of ...
