Draft Genome Sequence of Oral Bacterium Streptococcus mutans JH1140
Streptococcus mutans JH1140 is an oral bacterium known to produce the bacteriocin mutacin 1140, and the strain has been genetically engineered to combat dental caries. Here, we report the 2.0-Mb draft genome of S. mutans JH1140. This genome provides new insights into the strain's superior colonization properties and its utility in replacement therapy.
متن کاملStreptococcus mutans-derived extracellular matrix in cariogenic oral biofilms
Biofilms are highly structured microbial communities that are enmeshed in a self-produced extracellular matrix. Within the complex oral microbiome, Streptococcus mutans is a major producer of extracellular polymeric substances including exopolysaccharides (EPS), eDNA, and lipoteichoic acid (LTA). EPS produced by S. mutans-derived exoenzymes promote local accumulation of microbes on the teeth, w...
متن کاملStreptococcal antagonism in oral biofilms: Streptococcus sanguinis and Streptococcus gordonii interference with Streptococcus mutans.
Biofilms are polymicrobial, with diverse bacterial species competing for limited space and nutrients. Under healthy conditions, the different species in biofilms maintain an ecological balance. This balance can be disturbed by environmental factors and interspecies interactions. These perturbations can enable dominant growth of certain species, leading to disease. To model clinically relevant i...
متن کاملSalivary interleukin-1β and Streptococcus mutans level in oral cavity
Many studies have revealed correlation between serum or salivary immunoglobulin concentration and the progress of caries. Pathogens residing in the oral cavity can stimulate immune cells to produce cytokines. Antibacterial cellular reaction of T-cells in course of caries is related to the expression of superficial antigens of Streptococcus mutans. Interleukin-1β (IL-1β) – one of the most import...
متن کاملStreptococcus Mutans and Lactobacillus Levels in Oral Cleft Patients
Aim. The aim of the present study was to search the manner in which cariogenic bacteria might coexist with know bacteria that produce volatile sulfur compounds and represent the cause of habitasis. Materials and methods. 100 patients aged 11-21y with palatal clefts and malocclusions were divided into two groups: group A was treated with fixed orthodontic appliances, group B was treated with rem...
