Species of the genus Rothia that inhabit the oral cavity have recently been implicated in a number of diseases. To minimize their role in oral infections, it is imperative to reduce and/or control the growth and biofilm formation activity of Rothia spp. In this study, two bacterial isolates, Ora-7
We report the draft whole-genome sequence of Rothia nasimurium isolated from a porcine tonsil. The genome encodes a nonribosomal peptide synthetase predicted to produce valinomycin, a cyclic dodecadepsipeptide ionophore. Previously, valinomycin was known to be produced only by Streptomyces species
A cephalexin and penicillin G resistant strain of Rothia dentocariosa was clinically isolated from pus of infected postoperative maxillary cyst. The strain contained multiple plasmids. Plasmid curing tests with rifampicin eliminated cephalexin and penicillin G resistant phenotypic functions and 47
Rothia dentocariosa is a rare gram-positive bacterial organism, one of the group of microbes that normally resides in the mouth and respiratory tract. R. dentocariosa rarely causes disease. Documented cases occur chiefly in patients with valvular or dental disease, or both. We report the case of a
We report a case of endocarditis and associated paravalvular abscess due to Rothia dentocariosa which did not respond to antibiotic therapy. Nine case reports describing endocarditis caused by this organism, formerly thought to be non-pathogenic, have been recorded in the literature. The isolates
A 27-year-old woman is described with Rothia dentocariosa endocarditis, the fourth such case described in the literature. Her course was complicated by brain abscess, which was treated successfully with antibiotics. It is believed this represents the first case of R. dentocariosa with central
Rothia aeria caused a necrotic lymphadenitis and neck abscess in a patient with CGD. This infection was aggressive, crossed tissue planes, required two surgeries, as well as prolonged antibiotics for complete resolution. Rothia aeria is a rare pathogen that can be added to the spectrum of agents
We aimed at reporting the first case of rapidly progressive acute postoperative endophthalmitis after phacoemulsification cataract surgery in an immunocompetent patient caused by Rothia mucilaginosa. An immunocompetent patient manifested endophthalmitis signs 48 hours after an uncomplicated cataract
Structural studies on the major glycolipid isolated from Rothia mucilaginosa were carried out utilising specific chemical degradation, NMR spectroscopy and matrix-assisted laser-desorption/ionization time of flight mass spectrometry (MALDI TOF-MS). The glycolipid was found to be a
Rothia species - Gram-positive pleomorphic bacteria that are part of the normal oral and respiratory flora - are commonly associated with dental cavities and periodontal disease although systemic infections have been described. We describe a 53-year-old female with rheumatoid arthritis complicated
Rothia mucilaginosa is a Gram-positive bacterium occurring as a commensal in the oral cavity and upper respiratory tract. Although rarely pathogenic in an immunocompetent host, it can cause severe opportunistic infections in immunocompromised individuals.A A 61-year-old patient presented with drowsiness, decreased appetite and weight loss. On examination he had several splinter haemorrhages and a tender mass over the right temporal region. Respiratory and abdominal examinations were unremarkable and heart sounds were normal with no clinically audible
Three cases, one each of native valve, prosthetic valve and composite graft endocarditis caused by Rothia dentocariosa are described. The first patient presented with multiple brain abscesses and severe congestive heart failure due to destructive endocarditis with large vegetations on the mitral
An 84-year-old woman with acute myelocytic leukemia presented with fever and a left upper lobe infiltrate on chest x-ray. She failed to respond to initial broad spectrum antibiotic therapy. Bronchoalveolar lavage fluid and a transthoracic needle aspirate subsequently both grew Rothia dentocariosa, a
Seriously compromised patients may acquire deep airway ailments by Gram positive, commensal bacteria including Kytococcus and Rothia, pathogenic tracts of which still remain quite unexplored. Resistances they express have been poorly investigated over the years, and no published guidelines for
