Abstract:
<em>Rothia mucilaginosa (R. mucilaginosa)</em> is a facultative, Gram-positive coccus that is considered to be part of the normal flora of the mouth and respiratory tract. There are sporadic reports of the organism causing endocarditis in patients with heart valve abnormalities, as well as meningitis, septicemia, and pneumonia associated with intravenous drug abuse. However, it is an unusual pathogen in cases of umbilical cord blood infection. Herein, we report a case of umbilical cord blood infection planned for marrow transplant by Rothia mucilaginosa.

A database search identified two rhomboid genes on the genome with open reading frames of 828 bp and 822 bp, respectively. The two genes are separated by 57 bp, suggesting that they constitute a bicistronic operon. Motifs conserved among rhomboid family proteins (HxxxN, GxSG, and GxxxG) were found in their

Rothia mucilaginosa is a Gram-positive coccus and an opportunistic pathogen in immunocompromised hosts. The microorganism has been implicated in serious infections, including bacteremia meningitis or endocarditis. However, there is a dearth of investigations on meningitis, especially in children. As this infection is rare and only a few cases have been recorded, evidence-based guidelines for adequate infection treatment are lacking.

Rothia mucilaginosa is an opportunistic pathogen in the human oral cavity and pharynx. We found that R. mucilaginosa DY-18, a clinical isolate from a persistent apical periodontitis lesion, had biofilm-like structures. Similar structures were also observed on R. mucilaginosa ATCC25296. To further study these structures, we determined the complete genome sequence of DY-18 and found it a 2.26-Mb chromosome. Regarding stress responsive systems known to affect biofilm formation in many bacteria, DY-18 genome possessed only two sigma factor genes. One of these encoded an additional sigma factor who

Gluten are proline- and glutamine-rich proteins present in wheat, barley, and rye and contain the immunogenic sequences that drive celiac disease (CD). Rothia mucilaginosa, an oral microbial colonizer, can cleave these gluten epitopes. The aim was to isolate and identify the enzymes and evaluate their potential as novel enzyme therapeutics for CD. The membrane-associated R. mucilaginosa proteins were extracted and separated by DEAE chromatography. Enzyme activities were monitored with paranitroanilide-derivatized and fluorescence resonance energy transfer (FRET) peptide substrates, and by glia

Rothia mucilaginosa (Rm) is a gram-positive bacterium residing in the oral cavity. Recent studies in our laboratory have shown that this microorganism is able to cleave gluten, including immunogenic domains implicated in celiac disease. This can be beneficial to patients with celiac disease because exploitation of Rm can provide a novel mode of treatment. The enzymes responsible for this cleavage are as yet unknown. The purpose of this study was to optimize the transformation efficiencies of Rm cells through electroporation, with the ultimate goal to create knock-out mutants for enzyme acti

Abstract Yeasts are found ubiquitously in nature, in association with plants, mammals, and insects. Accordingly, humans are continually exposed to multiple genera of yeasts via various routes. Depending on the interaction between host mucosal defense mechanisms and fungal virulence factors, yeast colonization may be transient or persistent, with either systemic or local disease. Yeast organisms are usually of low virulence, and frequently require a significant alteration or reduction in host defenses prior to tissue invasion.
