Summary
Gut microbial dysbiosis, an imbalance in gut bacteria, is linked to inflammatory bowel diseases (IBD) and colorectal cancer (CRC). This review examines how dysbiosis influences colitis and CRC, focusing on specific bacteria like E. coli and F. nucleatum.
Area of Science:
- Gastroenterology
- Microbiology
- Oncology
Background:
- The gut microbiota is crucial for maintaining intestinal homeostasis, influencing barrier function, immunity, and metabolism.
- Microbial dysbiosis, an imbalance in gut bacteria, is increasingly associated with intestinal disorders such as inflammatory bowel diseases (IBD) and colorectal cancer (CRC).
Purpose of the Study:
- To review recent evidence linking gut microbial dysbiosis to the development of intestinal diseases, specifically colitis and CRC.
- To discuss the biological events contributing to dysbiosis and the emergence of CRC-associated microorganisms.
- To examine the mechanisms by which specific bacteria, Escherichia coli (E. coli) and Fusobacterium nucleatum (F. nucleatum), may promote colorectal cancer.
Main Methods:
- Literature review of recent scientific evidence.
- Analysis of biological events implicated in microbial dysbiosis.
- Focus on the role of E. coli and F. nucleatum in colorectal cancer development.
Main Results:
- Gut microbial dysbiosis is a significant factor in the pathogenesis of colitis and CRC.
- Specific microorganisms, including E. coli and F. nucleatum, are frequently associated with CRC.
- These bacteria may exert carcinogenic effects through various mechanisms impacting host cells.
Conclusions:
- Gut microbiota dysbiosis plays a critical role in the development and progression of intestinal diseases like colitis and CRC.
- Understanding the mechanisms by which bacteria like E. coli and F. nucleatum contribute to CRC is essential for developing targeted therapies.
- Further research into the gut microbiome's role in cancer is warranted.

01:27Microbiota of the Large Intestine
94
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

01:29Bacterial Flora of the Large Intestine
1.6K
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.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...

Firmicutes is a diverse phylum of Gram-positive bacteria characterized by a low GC content in their genomes. This phylum includes organisms with monoderm or diderm cell envelopes, highlighting a complex evolutionary history. Firmicutes comprises several major orders, including Lactobacillales, Clostridiales, and Bacillales, which exhibit remarkable diversity in their morphology, metabolism, and ecological roles.The order Lactobacillales includes lactic acid bacteria, which are fermentative...
