Introduction to the Human Microbiota

Introduction to the Human Microbiota

Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity, and disease...

The Oral Microbiota

The Oral Microbiota

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...

Development of the Oral Microbiota

Development of the Oral Microbiota

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,...

Area of Science:

Microbiology
Oral Biology
Tissue Engineering

Background:

The oral cavity is a reservoir for pathogens, and understanding host-microbiome interactions is crucial for various disease states.
Traditional culture methods struggle to replicate the complex gingival architecture and physiological characteristics of the periodontal niche.

Purpose of the Study:

To investigate host-microbiome interactions in healthy conditions using a novel human oral tissue model.
To assess the viability and function of the host tissue and microbial communities over seven days.

Main Methods:

Development and utilization of an in vitro human oral tissue model.
Monitoring of host-microbiome interactions over a seven-day period.
Assessment of host barrier integrity, functional response, and microbial community dynamics.

Main Results:

The in vitro model demonstrated long-term viability of both host tissue and microbial populations.
Host barrier integrity and phenotypic functional responses were preserved.
Healthy microbial populations and interbacterial communication were maintained.

Conclusions:

The developed in vitro platform successfully maintains tissue homeostasis within the periodontal niche.
This model offers a valuable tool for identifying predictive oral disease biomarkers.
The platform can aid in developing novel intervention strategies for promoting oral and overall health.
