Summary
The vaginal microbiome (VMB) significantly impacts preterm birth (PTB) risk, varying across diverse populations. Understanding these VMB differences is key to developing targeted strategies for PTB prevention.
Area of Science:
- Microbiology
- Reproductive Health
- Genetics
Background:
- Preterm birth (PTB) remains a major global health concern with unclear causes.
- The vaginal microbiome (VMB) is increasingly recognized for its role in pregnancy outcomes.
- Significant ethnic variations in VMB composition exist.
Purpose of the Study:
- To review normal VMB in pregnant and non-pregnant women.
- To explore VMB differences in ethnically diverse populations experiencing PTB.
- To emphasize the importance of VMB in PTB etiology and prevention.
Main Methods:
- Literature review of studies on VMB and PTB.
- Comparative analysis of VMB across different ethnic groups.
- Synthesis of current knowledge on VMB-PTB associations.
Main Results:
- VMB composition differs significantly between individuals and populations.
- Specific VMB profiles are associated with increased PTB risk.
- Ethnic background influences VMB structure and its relation to PTB.
Conclusions:
- Understanding population-specific VMB is crucial for PTB risk assessment.
- Targeted interventions based on VMB profiles may reduce PTB incidence.
- Further research is needed to clarify microbial mechanisms and develop personalized approaches.

01:28Development 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,...
01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
01:22Introduction 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...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:23Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
