Summary
Extracellular DNA is crucial for oral biofilm structure and development. Targeting this DNA offers a promising strategy for controlling microbial biofilms on oral surfaces.
Area of Science:
- Microbiology
- Biochemistry
- Oral Health
Background:
- The extracellular matrix (ECM) is vital for microbial biofilm formation and function.
- Extracellular DNA (eDNA) is increasingly recognized as a key component of the ECM in oral biofilms.
- eDNA influences biofilm integrity, adhesion, and nutrient balance within the oral cavity.
Purpose of the Study:
- To review recent advancements in understanding the role of eDNA in oral biofilms.
- To explore the therapeutic potential of targeting eDNA for managing oral biofilm-related conditions.
Main Methods:
- Literature review of current research on eDNA in oral biofilms.
- Analysis of studies investigating biofilm formation and integrity.
- Evaluation of potential strategies for eDNA-based interventions.
Main Results:
- eDNA significantly contributes to the structural stability of oral biofilms.
- eDNA plays a role in the adhesion of biofilms to both hard and soft oral tissues.
- Emerging evidence highlights eDNA's involvement in nutrient homeostasis within biofilms.
Conclusions:
- Extracellular DNA is a critical determinant of oral biofilm architecture and persistence.
- Targeting eDNA presents a viable and novel approach for the control of oral biofilms.
- Further research into eDNA-modulating agents could lead to new treatments for oral biofilm diseases.

01:27The Oral Microbiota
57
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

2.0K
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

51.2K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

01:28Development of the Oral Microbiota
42
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

00:58Genomic DNA in Eukaryotes
54.5K
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.
