Corynebacterium matruchotii is a reported calcifying bacterium that can usually be isolated from dental calculus and induce mineralization in vitro. In recent years, based on in situ hybridization probe and sequencing technology, researchers have ...

Some studies report C. matruchotii to be enumerated in caries-free children and young adults [7,13], and reduced in caries progression . However, a yet unnamed Corynebacterium phylotype has been found to be among the predominant species related to caries progression in the primary and permanent dentition [ 14 ].

2022年7月5日 · Streptococcus mutans is the primary pathogen of dental caries, and based on its strong ability of acid production and acid resistance, along with its possession of glycotransferase, it can use dietary sugar to produce insoluble glucans to form oral biofilm and generate acid to decalcify dental enamel and cause caries (Johansson et al., 2016).

Commensal microbes, such as certain streptococci and Corynebacterium spp., play crucial roles in maintaining oral health through mechanisms involving hydrogen peroxide production and membrane vesicle secretion, which can inhibit pathogenic species and …

2025年3月1日 · High-throughput sequencing of saliva and supragingival plaque microbiota from 102 children with dental caries showed a bacterial community dominated by the genera Streptococcus and Haemophilus in saliva, and the genera Neisseria, Leptotrichia, Fusobacterium, Corynebacterium, Schaalia, Rothia, Veillonella, and Prevotella in plaque.

2022年7月6日 · Corynebacterium matruchotii is a reported calcifying bacterium that can usually be isolated from dental calculus and induce mineralization in vitro . In recent years, based on in situ hybridization probe and sequencing technology, researchers have discovered the …

Corynebacterium matruchotii, Lautropia mirabilis, Neisseria elongata, and Corynebacterium durum were relatively more abundant in the caries-free group (p < 0.05). Species belonging to the Leptotrichia, Prevotella, and Veillonella genera were significantly predominant in …

2021年1月1日 · Of the topmost abundant species cultivated in this study, Corynebacterium matruchotii, C. durum, N. elongata, and L. mirabilis were significantly more abundant in caries-free children. Corynebacterium spp. are gram‐positive bacilli …

2023年4月10日 · The caries children harbored a significantly higher proportion of Corynebacterium in the mixed dentition group, while samples from caries lesions showed a significant decrease in Fusobacterium and TM7.

2024年10月31日 · Here, we present that Corynebacterium durum, itself and through its extracellular membrane vesicles disrupts interkingdom assemblages between C. albicans and S. mutans. Mechanistically the interaction interference occurs at the genetic level with downregulated HWP1 expression, a surface protein specifically induced …
