Rothia

Rothia

(roth'ē-ă),
A genus of nonmotile, non-spore-forming, non-acid-fast, aerobic to facultatively anaerobic bacteria (family Actinomycetaceae) containing gram-positive, coccoid, diphtheroid, or filamentous cells; metabolism is fermentative, and glucose fermentation yields primarily lactic acid but no propionic acid. These organisms are normal inhabitants of the human oral cavity and are opportunistic pathogens. The type species is Rothia dentocariosa.

Group 3, (the sub- and supra-gingival plaque biofilm) showed the greatest bacterial diversity and had a further decrease in Firmicutes compared to Groups 1 and 2, with a marked increase in the relative abundance of Actinobacteria and with a similar profile of genera as Group 2 plus Corynebacterium, Capnocytophaga, Rothia and Porphyromonas (6)
Vaccination with PCV-7 resulted in a shift in bacterial community composition and structure, with an increase in presence or abundance of several anaerobes, such as Veillonella, Prevotella, Fusobacterium, and Leptotrichia species; gram-positive bacteria, such as Actinomyces and Rothia species, and nonpneumococcal streptococci; and gram-negative Neisseria species.

Upon manual review, 12 were confirmed without changes, 2 clusters contained at least 1 isolate with >1% sequence difference in pairwise comparisons, 2 clusters were split because of >1% sequence heterogeneity, and isolates of 3 clusters could be identified to validly described species: Rothia aeria, Cardiobacterium hominis, and Streptomyces thermoviolaceus subsp.
