Description:Normally found as an inhabitant of the human mouth and respiratory tract, this Gram-stained photomicrograph revealed numerous Gram-positive Rothia dentocariosa bacteria.
You’ll note that the clustering of these organisms giving rise to a filamentous patterning as they attach to one another; R. dentocariosa has also been observed as coccoid-shaped. R. dentocariosa was originally isolated from samples of dental caries, hence its name. Rarely causing disease in humans, this bacterium has been implicated as a pathogenic agent in diseases that include endocarditis (heart inflammation), peritonitis (inflammation of the peritoneum), tonsillitis (inflammation of the tonsils), pneumonitis, and corneitis (corneal inflammation).
