Insights

Children with cleft palate have altered oral and nasal microbiomes, with reduced diversity and different bacterial compositions. This oral microbiome disturbance may link to increased infectious disease risk.

Area of Science:

  • Microbiology
  • Genetics
  • Pediatrics

Background:

  • Cleft palate is associated with a higher prevalence of infectious diseases.
  • The oral and nasal microbial profiles in children with cleft palate are not well understood.

Purpose of the Study:

  • To identify the oral and nasal microbial profiles in children with cleft palate.
  • To compare these profiles with those of healthy children.
  • To explore potential links between the microbiome and infectious diseases.

Main Methods:

  • Analysis of saliva and nasal samples from 10 cleft palate children and 10 age-matched controls.
  • DNA isolation, PCR-DGGE for microbial fingerprinting, and DNA sequencing.

Main Results:

  • Significantly lower saliva microbial diversity in cleft palate children.
  • Distinct microbial compositions in saliva and nares of cleft palate children.
  • Increased oral-nasal microbial similarity in cleft palate children.
  • Reduced presence of Lautropia and Bacillus species in cleft palate children's saliva.
  • Fewer Dolosigranulum and Bacillus species in cleft palate children's nasal cavities.
  • Predominance of Streptococcus species in the nasal cavities of cleft palate children.

Conclusions:

  • Children with cleft palate exhibit a disturbed oral and nasal microbiome.
  • Abnormal communication between oral and nasal cavities may contribute to microbiome alterations.
  • Further research is needed to establish the relationship between the disturbed microbiome and disease.

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,...

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...

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...

Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

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...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
