Vagina01:26

Vagina

21.2K
The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...

Surface Membrane Barriers01:18

Surface Membrane Barriers

2.4K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Anatomy of the Intestines

86.1K
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...

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

1.2K
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Bacterial Phylum Verrucomicrobiota01:26

Bacterial Phylum Verrucomicrobiota

367
The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...

Area of Science:

  • Reproductive health
  • Microbiology
  • Obstetrics

Background:

  • Vaginal microbiota plays a crucial role in pregnancy outcomes.
  • Understanding the link between vaginal flora and preterm labor is essential for improving maternal and infant health.

Purpose of the Study:

  • To investigate the association between vaginal microbiota composition and threatened premature labor.
  • To determine if vaginal microbiota can predict preterm delivery in women experiencing threatened premature labor.

Main Methods:

  • A prospective study involving 64 pregnant women.
  • Vaginal microbiome analysis using 16S ribosomal RNA sequencing.
  • Comparison of microbiota between threatened premature labor and other conditions, and between preterm and full-term deliveries.

Main Results:

  • No significant differences in vaginal microbiota were found between threatened and non-threatened premature labor groups.
  • Significant differences in Nugent score, Lactobacillus species percentage, bacterial species count, and Ureaplasma species positivity were observed between preterm and full-term delivery groups.
  • Ureaplasma species positivity was identified as a predictive factor for preterm delivery in women with threatened premature labor (OR, 6.5).

Conclusions:

  • Increased Ureaplasma species in vaginal microbiota is a risk factor for preterm delivery in threatened premature labor.
  • Vaginal microbiome analysis shows potential for identifying pregnancies at high risk for preterm delivery.
