Fifty isolates of Rothia dentocariosa from diverse clinical sources were characterized by 28 separate tests. An attempt was made to select practical tests that could be completed in a minimal length of time. Rothia is also compared with Actinomyces and Nocardia with which it is often confused. Of the isolates 100% were positive in the following reactions: catalase production, nitrate and nitrite reduction, esculin hydrolysis, and acid production from glucose, sucrose, maltose, salicin, and glycerol. The importance of recognizing this organism is based on the fact that it is frequently isolated from human clinical materials and must be differentiated from morphologically similar organisms of the genera Actinomyces and Nocardia, which contain pathogenic members.

Molar incisor hypomineralization (MIH) is a qualitative developmental defect that affects the enamel tissue of permanent molars and can also occur in permanent incisors. Enamel affected by MIH has reduced hardness, increased porosity, and a higher organic content than unaffected enamel. These characteristics predispose the enamel to accumulation of bacteria and a higher prevalence of caries lesions.

We report a case of a late adolescent female who presented to us with complaints of acute, painful loss of vision in her left eye. Her visual acuity (VA) had reduced to perception of hand movements within a week. Slit lamp examination and ultrasonography revealed that the patient had endophthalmitis.

Article Synopsis
- The text discusses a rare case of deep neck cellulitis, myositis, and reactive lymphadenitis caused by a typically low-virulence commensal organism found in the throat and respiratory system.
- A 35-year-old immunocompetent woman with no significant health issues presented symptoms like neck pain, fever, and chills, leading to a diagnosis confirmed by blood cultures.
- The patient recovered completely after antibiotic treatment, emphasizing the need to understand the potential virulence of this organism in healthy individuals, despite its usual association with more severe illness in immunocompromised patients.

Background And Aims: Even in the absence of inflammation, persistent symptoms in Crohn's disease (CD) are prevalent and worsen quality of life. Amongst patients without inflammation (quiescent CD), we hypothesized that microbial community structure and function, including tryptophan metabolism, would differ between patients with persistent symptoms () and without persistent symptoms ().
Methods: We performed a multicenter observational study nested within the Study of a Prospective Adult Research Cohort with Inflammatory Bowel Disease.
