Summary
Diet significantly impacts the diversity of Prevotella copri strains within the gut microbiome. This microbial adaptation highlights the intricate relationship between host diet and gut ecosystem function.
Area of Science:
- Microbiology
- Gut Microbiome Research
- Host-Microbe Interactions
Background:
- The gut microbiome plays a crucial role in host health.
- Prevotella copri is a common gut bacterium with diverse strain characteristics.
- Diet is known to influence the overall composition of the gut microbiota.
Purpose of the Study:
- To investigate the influence of host diet on the strain-level diversity of Prevotella copri.
- To understand the functional adaptations of gut microbial ecosystems in response to dietary changes.
Main Methods:
- Analysis of Prevotella copri strain-level diversity using marker gene profiling.
- Examination of assembled pangenomes to identify individual microbial signatures.
- Correlation of microbial signatures with host dietary patterns.
Main Results:
- Host diet demonstrably shapes the strain-level diversity of Prevotella copri.
- Distinct individual microbial signatures were identified within the Prevotella copri population.
- Evidence suggests functional adaptation of microbial ecosystems driven by diet.
Conclusions:
- Diet is a significant driver of Prevotella copri strain diversity in the gut.
- Understanding strain-level variations is key to comprehending microbial ecosystem function.
- This study provides a rationale for targeted dietary interventions to modulate the gut microbiome.

Archaea, a domain of single-celled microorganisms, are classified into five major phyla based on genetic and biochemical characteristics: Euryarchaeota, Crenarchaeota, Thaumarchaeota, Korarchaeota, and Nanoarchaeota. Among these, the phylum Euryarchaeota is notable for its remarkable diversity in morphology, metabolism, and ecological adaptations.Morphological and Metabolic DiversityMembers of Euryarchaeota exhibit a variety of cellular shapes, including rods and cocci. Their metabolic pathways...

Archaea, one of the three domains of life, exhibit remarkable diversity and adaptability, thriving in both extreme and moderate environments. Historically, most identified archaea have been classified into two major phyla: Euryarchaeota and Crenarchaeota. However, recent molecular studies have expanded this classification to include three additional phyla: Thaumarchaeota, Nanoarchaeota, and Korarchaeota, each exhibiting unique characteristics and ecological roles.Thaumarchaeota: Mesophiles...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

1.5K
Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
