Bacteroides
Bacteroides: The Mysterious Gut Dweller
Description
Bacteroides are a genus of Gram-negative, anaerobic bacteria found in the human gut microbiota. They are one of the most abundant bacterial groups in the colon, comprising up to 20% of the total bacterial population. Bacteroides are rod-shaped and possess a variety of virulence factors, including capsule, fimbriae, and flagella.
Associated Diseases
Bacteroides species have been implicated in a range of human diseases, including:
- Gut inflammation: Bacteroides can produce pro-inflammatory molecules that contribute to intestinal inflammation and diseases such as Crohn‘s disease and ulcerative colitis.
- Colon cancer: Certain Bacteroides species have been linked to an increased risk of colon cancer.
- Endocarditis: Bacteroides can cause infective endocarditis, a serious heart infection.
- Sepsis: Bacteroides are a common cause of sepsis, a life-threatening systemic inflammatory response.
Did you Know ?
Bacteroides are estimated to outnumber human cells in the gut by a ratio of 10:1. This vast population plays a crucial role in maintaining gut health and immunity.
