Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

1.4K
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.

Bacterial Phylum Tenericutes01:24

Bacterial Phylum Tenericutes

371
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Types of Microorganisms01:29

Types of Microorganisms

1.4K
Microorganisms are a diverse group of microscopic entities broadly categorized into cellular and acellular types based on their structural organization. Cellular microorganisms include bacteria, archaea, fungi, protozoa, and algae, while acellular microorganisms are represented by viruses.Cellular MicroorganismsBacteriaBacteria, tiny prokaryotic organisms, exhibit fascinating shapes such as rods, spheres, and spirals. They adapt to diverse habitats, including soil, water, and human-associated...

Bacterial Phylum Verrucomicrobiota01:26

Bacterial Phylum Verrucomicrobiota

437
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,...

Microbial Nutrition01:28

Microbial Nutrition

938
Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Anatomy of the Intestines01:23

Anatomy of the Intestines

86.3K
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...

Area of Science:

  • Microbiology
  • Dermatology
  • Human Microbiome Research

Background:

  • The human skin harbors a complex microbiome comprising bacteria, fungi, viruses, and mites.
  • Individual microbiomes are shaped by intrinsic and environmental factors, creating unique microbial niches across body sites.

Purpose of the Study:

  • To investigate the unique microbial niches of the human foot.
  • To characterize the bacterial and fungal communities inhabiting healthy foot skin.

Main Methods:

  • Analysis of microbial communities in different foot skin areas.
  • Consideration of factors like skin thickness, anatomy, sweat gland distribution, pH, and oxygen availability.

Main Results:

  • Healthy foot skin hosts diverse bacteria, including Corynebacteriaceae, Micrococcaceae, and Proteobacteria.
  • Common foot fungi include Malassezia, Candida, Aspergillus, and Trichophyton species.

Conclusions:

  • Foot microbiome dysbiosis is linked to skin conditions such as pitted keratolysis.
  • Imbalances in the foot microbiome may predispose individuals to fungal and viral infections.
