Bacteroides finegoldii
Relatedness to other species in the Bacteroides genus
16S rRNA gene sequence similarities show that B. finegoldii's closest neighbors are Bacteroides thetaiotaomicron and Bacteroides ovatus.
Characteristics
General Background
B. finegoldii is a strictly anaerobic, Gram-negative rod bacteria that occurs in human feces.
Morphology
B. finegoldii is non-spore-forming, non-motile, Gram-negative rods, about 0.80 µm wide and 1.5-4.5 µm long and occur singly.
Molecular structure
The major fatty acids are anteiso-C15:0 (31.8–36.2%) and iso- C17:0 3-OH (13.1–14.5%). The DNA G+C content is 42.4–43.0 mol%.
Metabolism
The optimum temperature for growth is about 37 C. B. finegoldii produces acid is fro–4.5 mm long, and occur singly. Colonies are 1–2 mm in diameter, circular, translucent–whitish, raised and convex.m the metabolism of glucose, lactose, sucrose, maltose, salicin, xylose, arabinose, cellobiose, mannose, raffinose and rhamnose. The bacteria grows in the presence of bile.
Current Research
Current research is investigating whether Bacteroides finegoldii is involved in the stool microbiome and metabolome of humans. Specifically, research us trying to differente between the stool microbiome and metabolome of colorectal cancer patients and healthy adults.
