BACKGROUND To report a case of Streptococcus mitis/oralis endophthalmitis management which had developed after complicated iris-fixated phakic intraocular (pIOL) lens implantation. CASE PRESENTATION A 23-year-old-woman received pIOL implantation followed secondary intraocular intervention to lower intraocular pressure. The patient presented with severe pain and decreased visual acuity and was...

Streptococcus sinensis is a recently discovered human pathogen isolated from blood cultures of patients with infective endocarditis. Its phylogenetic position, as well as those of its closely related species, remains inconclusive when single genes were used for phylogenetic analysis. For example, S. sinensis branched out from members of the anginosus, mitis, and sanguinis groups in the 16S ribo...

We recently described the novel species Streptococcus tigurinus sp. nov. belonging to the Streptococcus mitis group. The type strain AZ_3a(T) of S. tigurinus was originally isolated from a patient with infective endocarditis. According to its phenotypic and molecular characteristics, S. tigurinus is most closely related to Streptococcus mitis, Streptococcus pneumoniae, Streptococcus pseudopneum...

background & importance: infections of the craniocervical junction are rare. case presentation: we present a case of infection by methicillin-sensitive staphylococcus aureus and streptococcus mitis that was not previously reported. conclusion: neurosurgeons must suspect for diagnosis and initiate broad antimicrobial therapy, including active agents against gram-negative and then initiate a targ...

1. A transglucosylase has been separated from cell extracts of Streptococcus mitis, and has been partially purified by chromatography on DEAE-cellulose. 2. The transglucosylase was present in the six strains of Streptococcus mitis that were examined, and the activity of the enzyme was the same whether the cells had grown on glucose or on maltose. Four of the strains could store intracellular io...

Attachment of bacteria to the host tissue is regarded as a crucial step in the development of many types of infections. Recent studies by us and others have shown that matrix proteins which serve as adhesion proteins for eucaryotic cells may also be recognized by some bacteria. In the present communication, we report that several strains of viridans streptococci are able to bind to laminin. Mos...

OBJECTIVE Streptococcus mitis is a predominant oral colonizer, but difficulties in genetic manipulation of this species have hampered our understanding of the mechanisms it uses for colonization of oral surfaces. The aim of this study was to reveal optimal conditions for natural genetic transformation in S. mitis and illustrate its application in direct genome editing. METHODS Luciferase repo...
