Insights

This study details methods for characterizing the oral mycobiome, the fungal community in the mouth. Understanding these fungi is crucial for oral health, especially in HIV patients.

Area of Science:

  • Microbiology
  • Immunology
  • Mycology

Background:

  • Oral microbiota impacts health and diseases like gingivitis, periodontitis, and oral candidiasis.
  • Oral microbes are linked to systemic conditions such as cancer and respiratory infections.
  • Limited knowledge exists on oral microbial interactions and host immune system influence.

Purpose of the Study:

  • To describe methods for characterizing the oral mycobiome.
  • To focus on the fungal component of oral microbiota, particularly in the context of HIV.
  • To advance understanding of the oral fungal community in health and disease.

Main Methods:

  • Characterization of the oral mycobiome.
  • Focus on fungal community analysis.
  • Methods applied in health and disease, with emphasis on HIV-associated oral candidiasis.

Main Results:

  • Recent characterization of the oral mycobiome in health and disease.
  • Specific focus on HIV-related oral conditions.
  • Detailed description of methodologies employed by the research group.

Conclusions:

  • Characterizing the oral mycobiome is essential for understanding oral health and disease.
  • The study provides a methodological framework for oral fungal community analysis.
  • Further research into the oral mycobiome, especially in immunocompromised individuals, is warranted.

The Oral Microbiota01:27

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 Microbiota01:28

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,...

Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

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...

Fungal Group Zygomycota01:29

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Oral Cavity01:11

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Microbiome of the Eye01:22

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
