|Etymology:||Genus name: named after the French microbiologist, A. R. Prévot, who was a pioneer in anaerobic microbiology |
Species epithet: melanin producing (note however, that the black pigment is composed of protoheme and not to melanin, as was originally believed)
|Old Species Name(s):||Bacteroides melaninogenicus|
|Type Strain:||Finegold B282 = ATCC 25845 = CCUG 4944 B = NCTC 12963|
|Macromorphology (smell):||Small glossy colonies (0.5-2 mm in diameter) with a black center, which fluoresces under UV light. After prolonged incubation, the colonies become completely black due to pigmentation (an heme derivative). Only a few strains are hemolytic.|
|Micromorphology:||Nonmotile pleomorphic rods|
|Gram +/Gram -:||G-|
|Disease:||Footrot and foot abscesses of cattle and wound infections in dog and cat|
|Hosts:||Cattle, dog and cat|
|16S rRNA Seq.:|
||About 50 species have been described within genus Prevotella. Many species, which were earlier affiliated with genus Bacteroides, have now been transfered to genus Porphyromonas or genus Prevotella. These three genera are related and belong to the order Bacteroidales.|
|Comment:||Is often isoleras together with Fusobacterium necrophorum and Trueperella pyogenes from animals suffering from foot rot.|

We have refined the classification and made it possible to filter species and subspecies with respect to multiple properties.
