BACTEROIDETES Meaning and
Definition
-
Bacteroidetes is a phylum of bacteria that is commonly found in various environments such as soil, water, and the gastrointestinal tracts of humans and animals. It is characterized by the presence of Bacteroides species, which are considered one of the most abundant and diverse groups of bacteria in the gut microbiota.
The Bacteroidetes phylum consists of Gram-negative, non-spore-forming, and anaerobic bacteria. They exhibit a wide array of metabolic capabilities and are known for their ability to degrade complex carbohydrates, such as dietary fibers, through the production of specialized enzymes. This allows them to play a crucial role in the breakdown and utilization of dietary compounds that would otherwise be indigestible by the host.
Bacteroidetes are important for maintaining the overall health and balance of the gut microbiota. They contribute to the synthesis of essential vitamins, metabolize bile acids, regulate the immune system, and protect against pathogens by competitive exclusion. Furthermore, alterations in the abundance of Bacteroidetes have been associated with various diseases, including obesity, inflammatory bowel disease, and colorectal cancer.
In addition to their presence in the digestive tract, Bacteroidetes can also be found in other environments. For example, they play a significant role in the degradation of organic matter in soil ecosystems, contributing to nutrient cycling and carbon turnover.
Overall, Bacteroidetes are a diverse group of bacteria with important ecological, metabolic, and health-related functions that are crucial for the balance and well-being of both the gut microbiota and various ecosystems.
Etymology of BACTEROIDETES
The word "Bacteroidetes" is derived from two components - "bacteroides" and "-etes".
"Bacteroides" is a genus of bacteria that was named by the French microbiologist Pierre Charles Édouard Pottevin in 1887. It comes from the Greek words "baktērion", meaning "little stick" or "rod", and "oidēs", meaning "like" or "resembling". This term was used to describe the rod-shaped appearance of these bacteria under the microscope.
The suffix "-etes" is a common taxonomic ending used in biology to designate a class. It comes from the Greek word "-ēstēs", meaning "one who follows" or "follower". It is often added to the stem of the taxonomic group to indicate a class of organisms.
