Bac·te·roi·da·ce·ae

(bak'ter-oy-dā'sē-ē),
A family of obligate anaerobic (microaerophilic species may occur), non-spore-forming bacteria (order Eubacteriales) containing gram-negative rods that vary in size from minute, filterable forms to long, filamentous, branching forms; pronounced pleomorphism may occur. Motile and nonmotile species occur; motile cells are peritrichous. Body fluids are frequently required for growth. Most species ferment carbohydrates, often with the production of acid; gas may be produced in glucose or peptone media. These organisms occur primarily in the lower intestinal tracts and mucous membranes of warm-blooded animals. They may be pathogenic. The type genus is Bacteroides.

El primero fue realizado en 81 pacientes, evaluando los cambios en nueve grupos de bacterias: Bacteroidaceae y Bifidobacterium (anaerobios obligados totales), Clostridium lecitinasa positivo y anaerobios facultativos (Lactobacillus, Enterobacteriaceae, Enterococcus, Staphylococcus, Pseudomonas y Candida).
En el patron depletado tanto el numero de anaerobios obligados totales (incluyendo Bacteroidaceae y Bifidobacterium) como el de anaerobios facultativos totales (incluyendo Lactobacillus, Enterobacteriaceae y Enterococcus) fue significativamente menor respecto a los otros dos.
Results from this study support previous studies which reported large populations or Bacteroidetes (including the families Bacteroidaceae and Porphyromonadaceae) and Firmicutes (including the families Clostridiaceae and Lachn.ospiraceae) present within the digestive tract, as well as organisms from the phyla Proteobacteria (including the families Enterobacteriaceae and Aeromonadaceae) and Verrucomicrobia.

Members of the Bacteroidaceae family have been demonstrated to be able to utilize a wide range of carbohydrates, including those that could form plant cell wall (cellulose, xylan, pectins, and [beta]-glucans and galactans), host mucopolysaccharides and glycoproteins [27].
Overall, patients with MS usually have gut dysbiosis and often reduced numbers of Faecalibacterium, Bacteroidaceae, and Prevotella.
Patients with MS can exhibit gut microbial dysbiosis, with increases in Methanobrevibacter Akkermansia [128], Desulfovibrionaceae [132], Actinobacteria, Bifidobacterium, Streptococcus [137], Firmicutes, Euryarchaeota [133], Ruminococcus [138], Pseudomonas, Mycoplana, Haemophilus, Blautia, and Dorea [140] and decreases in Butyricimonas [128], Lachnospiraceae, Ruminococcaceae [132], Faecalibacterium, Prevotella, Anaerostipes, Clostridia XIVa and IV Clusters [137], Fusobacteria [133], Bacteroidaceae [138], C.
Famihes Bacteroidaceae (7.1% [+ or -] 1.5%) and Paraprevotellaceae (5.6% [+ or -] 0.9%) were significantly more abundant in the large intestine than other gastrointestinal tract sections.
