Draft Genome Sequence of the Oral Commensal Streptococcus oralis 89a with Interference Activity against Respiratory Pathogens
نویسندگان
چکیده
We report the draft genome sequence of the oral commensal Streptococcus oralis 89a isolated from the throat of a healthy child during a streptococcal tonsillitis outbreak in Umeå, Sweden. S. oralis 89a was known to have interference activity against respiratory pathogens in which the colicin V was the potential bacteriocin-encoding gene.

Hydrogen Peroxide Contributes to the Epithelial Cell Death Induced by the Oral Mitis Group of Streptococci
Members of the mitis group of streptococci are normal inhabitants of the commensal flora of the oral cavity and upper respiratory tract of humans. Some mitis group species, such as Streptococcus oralis and Streptococcus sanguinis, are primary colonizers of the human oral cavity. Recently, we found that hydrogen peroxide (H2O2) produced by S. oralis is cytotoxic to human macrophages, suggesting ...
متن کاملIn vitro antimicrobial effect of different root canal sealers against oral pathogens
Background and Purpose: Root canal therapy is the primary method for the treatment of an infected pulp in modern dentistry. The main aim of endodontic treatment is the elimination of bacteria and their products from infected root canals. In this study, we attempted to investigate the antimicrobial activity of three root canal sealers against oral pathogens. Materials and Methods: The antimic...

Background: Despite the availability of a wide range of antibiotics, bacterial infections are among important challenges for the healthcare system. Therefore, the introduction of new antimicrobial preparations such as platelet-rich plasma (PRP) could be suggested theoretically as a preventive measure for bacterial infections. We aimed to evaluate the in vitro antibacterial activity of PRP again...

Methanobrevibacter oralis, an anaerobic methanogenic archaeon, has been previously isolated from the human oral cavity. Here, sequencing a stool isolate (strain JMR01) yielded a 2.065-Mb genome with a 27.78% G+C content containing a total of 2,042 open reading frames and 3 clusters of regularly interspaced short palindromic repeat (CRISPR) loci with associated Cas proteins.
