Introduction: Description and significance

Prevotella histicola are Gram-negative bacilli that are obligately anaerobic, vary in pigmentation and are non-motile. Prevotella histicola is found in the mucosal tissues of the human oral cavity and is considered a normal flora of the human oral microbiota.[2] It is generally commensal but are known to intrude the epithelial cells lining the cheeks. The human oral cavity is the threshold to the human body. Energy, food, enters the mouth, is broken down and is mixed with saliva prior to traveling through the remainder of the body. This aids in the possibility of spreading the bacteria from the mouth to other parts of the body. Prevotella is the largest genus, with approximately fifty species.[5] The Prevotella species are affiliated with many oral diseases and certain infections found in other areas of the human body.[2][3] The human oral cavity consist of many different habitats, including teeth, gingival sulcus, tongue, cheeks, hard and soft palates, and tonsils which are colonized by bacteria. The oral microbiome is comprised of over six hundred prevalent taxa at the species level, with distinct subsets predominating at different habitats.[5]

Genome Structure Phylogeny

At this time very little is known about Prevotella histicola. The most recent research reveals a genome size of 0.7 X 0.8-3.0 um while colonies are 1.5-2.0mm in diameter, circular, entire, convex, cream-coloured and opaque.[2]
